Alternate tunings are any guitar tunings that differ from the standard E–A–D–G–B–E. These tunings broaden the guitar’s sonic palette, offering new chord voicings, drone notes, and extended ranges . Alternate tunings are especially common in folk, blues, and various rock genres, and they can make certain musical passages easier to play (while making others more difficult) . Broadly, alternate tunings fall into categories such as drop tunings, open tunings, modal tunings, and other specialized systems . In this article, we’ll explore drop tunings, open tunings, and other popular alternative tunings for 6-string guitar, focusing on their theory, practical use, benefits, challenges, and examples. Intermediate and advanced guitarists will gain insight into how these tunings work and how to integrate them into playing and songwriting.

Drop Tunings: A drop tuning lowers the pitch of one or more strings (almost always the lowest string) compared to standard tuning . In practice, “drop” usually means tuning the 6th (lowest) string down a whole step from its standard pitch. For example, Drop D tuning is D–A–D–G–B–E, where the low E is dropped to D . More extreme drop tunings drop the low string further (and often down-tune all strings for overall lower pitch). Common examples include Drop C(C–G–C–F–A–D) and Drop B (B–F♯–B–E–G♯–C♯), which provide an even deeper range for heavy music . Drop tunings are popular in rock and metal for their heavier sound and easy power chord shapes.

Open Tunings: An open tuning adjusts the strings so that strumming all open strings produces a clear chord, usually a major triad . For instance, Open G is D–G–D–G–B–D, which sounds a G major chord (D–G–B) when open . Likewise, Open D is D–A–D–F♯–A–D, a D major chord . Open tunings can also be minor chords (called cross-note tunings) or suspended chords (neither major nor minor, e.g. DADGAD) . These tunings are common in blues, folk, and slide guitar styles, allowing full chords with a barre and providing resonant drone strings .

“Other” Alternate Tunings: Beyond drop and open tunings, guitarists use many other alternate tunings for specific purposes. This includes down-tuned standard (lowering all strings equally, such as tuning every string down a half-step or whole step), modal tunings like DADGAD that form a suspended chord, and special approaches like Nashville tuning, where string gauges are changed to pitch some strings an octave higher (mimicking a 12-string guitar) . We’ll delve into these later. Each alternate tuning type has unique theoretical implications for intervals, chord shapes, and tonal center, which we’ll discuss along with practical uses.

Theoretical Shifts in Alternate Tunings

Changing the tuning alters the intervals between strings and thus the geometry of scales and chords on the fretboard. In standard tuning (E–A–D–G–B–E), the intervals between adjacent strings are mostly perfect fourths (5 semitones), except between G and B which is a major third (4 semitones). Alternate tunings will modify this pattern:

Drop Tunings: In Drop D (D–A–D–G–B–E), the interval between the 6th and 5th string becomes a perfect fifth (D to A) instead of a fourth, while the rest remain standard. This means the low D and A form a power chord (root-fifth) when played open together . In fact, the lowest three strings in Drop D (D–A–D) make an “open power chord” (D5 chord: D–A–D) . Consequently, any power chord (root + fifth) can be fretted with one finger across the lowest two strings – a fundamental ease-of-play benefit. Drop “X” tunings (Drop C, Drop B, etc.) follow the same idea: the 6th string is tuned a whole step lower than it would be in equivalent standard tuning. For example, Drop C can be seen as standard D tuning with the low string dropped to C. In all drop tunings, the 6th-to-5th string interval is a fifth, so one-finger power chords work similarly, just transposed to the new pitches.

Open Tunings: In open tunings, the intervals are arranged to form a chord. For example, Open G (D–G–D–G–B–D) has intervals that spell out a G-major chord: from low D up to G is a perfect fifth, G to the next D a fourth, D to G a fourth, G to B a major third, and B to D a minor third. The exact sequence of intervals varies, but the open strings include a root, third, and fifth of a chord (for major open tunings) . Because of this, barre chords become simple – sliding a single barre fret-to-fret transposes the major chord up the scale . However, scale patterns and non-barre chord shapes in open tuning can differ drastically from standard. Some open tunings (like DADGAD) are modal: DADGAD (D–A–D–G–A–D) produces a Dsus4 chord (D–G–A) with no major or minor third, giving an open suspended sound . This modal open tuning keeps intervals like D–A (a fifth), A–D (fourth), D–G (fourth), G–A (whole tone), A–D (fourth). The presence of that whole tone (G to A) in the middle is unusual, providing a drone-friendly configuration and ambiguous tonality (neither D major nor D minor) – useful for Celtic music and songs like Led Zeppelin’s “Kashmir” which uses DADGAD .

Other Alternate Tunings: Down-tuned standard tunings (e.g. every string one semitone down to E♭) preserve the interval pattern (all fourths and a third) . Thus, chord shapes and scales retain their relative patterns, only everything sounds lower in pitch. This means you don’t have to relearn fretboard patterns; however, the key of everything shifts down. For example, standard E-major open chord shape becomes E♭ major in E♭ tuning. In contrast, Nashville tuningkeeps the same open-string notes as standard (E–A–D–G–B–E), but the lower four strings are tuned an octave higher than usual . That yields a very close interval range (all strings within a major tenth of each other) and a shimmering treble-rich sound, but it’s essentially the same pitches as standard—just lacking low bass. Other creative tunings might introduce consistent intervals (e.g. all fourths tuning E–A–D–G–C–F) or other patterns, which can simplify certain theory at the cost of losing familiar chords.

Understanding these interval shifts is key: alternate tunings often make some chords trivially easy (e.g. one-finger power chords in drop tuning, or open-string major chords in open tuning) , but they can make other chords harder (you might need new fingerings for chords that were simple in standard) . Each tuning tends to favor certain tonal centers and chord types – for instance, Drop D naturally centers around D (giving a resonant low D), and open tunings strongly center on the chord they are tuned to. Next, let’s look at each category in detail.

Drop Tunings: Low Strings, High Impact

Definition: Drop tunings start from standard tuning and “drop” the pitch of the lowest string, usually by one whole step . In the most common case (Drop D), only the 6th string is changed (E down to D), whereas tunings like Drop C or Drop B involve dropping the 6th string and typically lowering all strings overall. Drop D is the simplest, sometimes called a “drop one” tuning (drop 1 whole tone on the 6th string) . If you tune to Drop D and then lower every string by the same amount (say a whole step down), you get Drop C (effectively drop tuning in D-standard) .

Theoretical Implications: Drop D results in D–A–D–G–B–E. The low D is an octave below the open 4th-string D (hence the name) . This gives the guitar two extra low semitones (D₂ and D♯₂) below the standard E₂ , extending the bass range. It also changes the interval pattern: the gap between the 6th and 5th string is now a perfect fifth (D to A) instead of a fourth. The immediate benefit is that the open 6th–5th–4th strings form a D5 power chord (D–A–D) . Power chords (root-fifth) that spanned two strings in standard tuning can now be played by barring one finger across the lowest two strings on the same fret. In standard tuning, a power chord like G5 (G–D) requires a two-finger shape (3rd fret low E and 5th fret A for G and D), but in Drop D, G5 can be played by fretting the 5th fret on both the 6th and 5th strings with one finger. As Wikipedia notes, in standard tuning a power chord needs two or three fingers, whereas in drop tuning it “needs just one,” making chord changes faster . The trade-off is that any chord or scale pattern involving the 6th string now has a shifted fingering. For example, an E major shape doesn’t produce an E chord in Drop D (since the 6th string is now D). Players must either avoid the altered string or learn new voicings for chords with that string.

Practical Uses: Drop tunings shine in genres needing quick chord shifts and a heavy low-end growl. In heavy metal and hard rock, Drop D and its lower cousins are extremely popular . The ability to slide one-finger power chords up and down enables rapid riffing and palm-muted chugs ideal for aggressive styles. Bands like Rage Against The Machine and Tool built signature riffs with drop-D power chords . The deeper tuning also adds weight: players get a heavier/darker sound by accessing the D (and D♯) below E . This was recognized early on by hard rock bands – The Beatles used Drop D on “Dear Prudence” (1968) and Led Zeppelin on “Moby Dick” (1969) to get a lower key and heavier vibe without fully downtuning . Many grunge and alternative rock bands in the 1980s (King’s X, Soundgarden, Melvins) embraced Drop D, influenced by Led Zeppelin and Black Sabbath’s explorations of lower guitar tones . This in turn influenced 90s alternative metal and nu-metal bands; for example, Helmet’s extensive use of Drop D paved the way for others . Beyond metal, drop tunings appear in folk and classical contexts as well. Classical guitarists have long used Drop D to reach low bass notes in pieces in D major or D minor – Drop D was introduced by 16th-century lutenists and guitarists to facilitate certain music . In acoustic folk, Drop D is common when the song’s key is D; it allows ringing open bass on D and fuller chord voicings. Neil Young’s “Harvest Moon” and many of his other songs use Drop D or Double Drop D for a rich, low D drone. In modern acoustic fingerstyle, drop tunings (and lowered tunings in general) also provide a deeper resonance and are often combined with techniques like percussive hits on the low string.

Benefits of Drop Tunings:

Easy Power Chords & Fast Riffs: As noted, one-finger power chords are a primary benefit . This simplification frees up fingers for embellishments and can make riff playing more ergonomic. Players can perform quick alternations and slides that might be awkward with standard tuning’s multi-finger power chords. Early drop-tuning adopters found they could articulate chords with legato techniques more easily .

Extended Bass Range: Drop tuning gives access to notes below the standard low E. For example, Drop D adds a low D and D♯ . This extended range can make the guitar sound more powerful, providing a deeper bass foundation especially useful in power trios or arrangements without a bassist doubling the low D. It also allows playing in the key of D (or related modes) with a strong root note: in standard tuning, a song in D can feel “empty” because you lack a low D note . With Drop D, a D chord can use all six strings (adding the low D note), creating a fuller sound .

Quick Re-tuning for Lower Keys: Drop D (and similar) is a convenient way to get a heavier sound or accommodate a lower vocal key without changing all strings. By only adjusting one string, a guitarist can temporarily lower the guitar’s tonal center. This is faster than retuning everything (useful in live settings to switch to a song in D), and avoids the slacker string tension that comes with tuning the whole guitar down. Historically, bands realized they could get a “heavier and darker sound” by drop-tuning the 6th string instead of going fully down to D standard . It’s a minor change with a noticeable effect.

• Creative Riffs and Drone Capabilities: The dropped string can act as a droning note (especially drop D acting as a pedal D note). Riffs can be written to alternate between the low open string and higher melody notes easily, which is a staple in metal (e.g. alternating open low D with other power chords). This pedal tone technique can also create a droning bass in folk or post-rock music.

Famous Examples: The list of songs and artists using drop tunings is long. Early examples include The Beatles’ “Dear Prudence” (Drop D) and Led Zeppelin’s “Moby Dick” (Drop D) from the late 60s . Black Sabbath often down-tuned guitars (though typically tuning all strings down to C♯ standard on some albums, Tony Iommi also occasionally used drop tuning techniques), pioneering the doomy low guitar sound. In the 90s, virtually every grunge band dabbled in drop D – Soundgarden (“Outshined”, “Spoonman” etc.), Nirvana (“All Apologies” is in Drop D), Alice in Chains, and others, giving their riffs extra heft. Rage Against the Machine’s Tom Morello used Drop D for songs like “Killing In The Name” to enable aggressive riffing and two-fret shifts. Tool and System of a Down (who often went to Drop C) used drop tunings for complex, heavy riffs. In metal, drop tunings (Drop C, Drop B, even Drop A) are ubiquitous in subgenres like metalcore and nu-metal for that deep, djent-worthy chug. On the acoustic side, Neil Young’s “Ohio” and “Cinnamon Girl” are in Double Drop D (both low E and high e tuned down to D) , creating a droning D modal tuning that gives those songs a distinctive suspended sound. Many contemporary worship or folk songs in D use Drop D to get a rich low end on the D chord without a bass. Table 1 summarizes a few common drop tunings and their uses:

Table 1: Common Drop Tunings (6-string)

Note: “Dropped Db (C#)” or others are analogous (e.g. Drop C# = Drop D down a half step). Many modern metal bands on 6-strings use Drop C or lower, while 7-string guitars achieve similar range with an extra string.

Open Tunings: Open Chords and Resonance

Definition: Open tunings tune the strings to a coherent chord, so that strumming all open strings yields a major or minor chord without any fretting . For example, Open D (D–A–D–F♯–A–D) produces a D major chord (D major triad) when played open , and Open G (D–G–D–G–B–D) gives a G major chord . The tuning is named after the chord (open D, open G, etc.). Most common open tunings are major; open minor tunings exist (often called cross-note, e.g. Open D minor: D–A–D–F–A–D), but they’re less frequently used in popular genres . Some tunings, like Open G6 or Open Cmaj7, add extra color tones. In any case, open tunings typically have a tonal center built-in, which strongly influences the music written in them.

Theoretical Implications: In an open major tuning, the open strings include at least three distinct pitch classes: the root, major third, and perfect fifth of a chord . For instance, Open E tuning (E–B–E–G♯–B–E) contains E (root), G♯ (major 3rd), B (5th) . Often notes are repeated in different octaves (open E has E and B each twice, and G♯ once). Because the guitar now sounds a full chord with no fingers, barre chords become extremely simple – moving a single barre up the neck transposes that major chord to any other root . With Open D, an open strum is D major; barre at 2nd fret gives E major, 3rd fret F major, etc. This is a huge boon for slide guitarists: by holding a slide straight across all strings, one can play major chords up the neck cleanly . Open tunings often feature repeating intervals or strings tuned in octaves, which can simplify certain scale runs but complicate others.

One hallmark of open tunings is the use of drone strings. Since the open strings form a chord, a guitarist can let one or more open strings ring as a drone while fretting others to play melodies. For example, in Open G (D–G–D–G–B–D), one can play a melody on the top strings while the lower D and G ring open, reinforcing the G chord. The MasterClass guide notes that open tunings facilitate drones – ringing one or more strings constantly while moving other notes . These drones create a rich, resonant backdrop and are common in folk and Indian-influenced music, as well as the blues (think of a constant bass note or two throughout a slide riff).

Open tunings also alter scale patterns. Because the string intervals are no longer the standard mix of fourths and a third, one has to map new patterns for scales. However, these new patterns often outline different modal possibilities. For instance, Open D (D major chord) naturally suggests playing in D major or D Mixolydian; Open G can suggest G major or G blues scale patterns easily accessible with slide and open notes. Some tunings, like DADGAD, have their own unique scale opportunities – DADGAD is often used for D mixolydian or D Dorian sounds in Celtic music, since the open strings (D–A–D–G–A–D) work as a Dsus4 backdrop that fits both D major and D minor melodies.

Practical Uses: Open tunings are widely used for slide guitar (lap steel or bottleneck style). Pioneering blues slide players like Robert Johnson and Son House tuned to open chords (Open G or Open D commonly) so that they could slide to play chords and riffs easily. In open tuning, placing a slide barre across all strings at the 12th fret in Open D, for example, yields a high D major chord; at the 5th fret it’s G major; at 7th fret A major, and so on. This makes playing blues in I–IV–V progressions very natural – one reason delta blues players favored open G (often tuned down to Open F or up to Open A) and open D/E. Even today, many blues-rock songs use open tuning for slide; The Allman Brothers Bandoften played slide in Open E (which is the same pitches as Open D but one step up), as in Elmore James’ “Dust My Broom.” Rock & Folk: Open tunings are a staple in folk and country blues fingerpicking. They allow for open-string drones and alternating bass notes that would be hard to grab in standard tuning. For example, open C (C–G–C–G–C–E) or open G are used by folk guitarists to get a full, harp-like sound – the guitar “rings” in a way that standard tuning doesn’t, since more strings resonate in harmony with the key.

Many singer-songwriters find inspiration in open tunings because common chord shapes from standard tuning no longer apply, leading to novel voicings. Joni Mitchell famously used dozens of alternate tunings (many open or modal) to craft unique chord progressions – she even developed a shorthand naming system for tunings . Nick Drake often used alternate tunings (like B–E–B–E–B–E on “River Man”) to achieve haunting, pianistic chords. With open tunings, simple two-finger shapes can yield complex chords thanks to the open strings supplying rich extensions. This is great for composition and improvisation; chords and riffs that would be technically difficult in standard become accessible, sparking creativity. Keith Richards of The Rolling Stones built his style around Open G tuning (often removing the low 6th string entirely). In Open G, he could play movable chord shapes with just a couple of fingers, achieving that signature riff-driven groove in songs like “Brown Sugar,” “Honky Tonk Women,” and “Start Me Up” . He found that eliminating the low string (which isn’t needed for the chord voicings in open G’s target keys) gave a cleaner sound and allowed focusing on the snappy middle strings.

Open tunings also excel in solo acoustic performance. An acoustic guitar in an open tuning can sound fuller, since strumming open or partial chords lets sympathetic vibrations fill out the sound. It’s almost like the guitar accompanies itself with drone and resonance. Many modern fingerstyle guitarists (Michael Hedges, Andy McKee, Pierre Bensusan) use open and alternate tunings to facilitate extended techniques and lush arrangements. For example, DADGAD (sometimes considered between open and modal) is a favorite of Celtic fingerstyle virtuosos because it allows melody and drones in D or G with great ease, and open-string hammer-ons/pull-offs that create harp-like cascades.

Benefits of Open Tunings:

• Full Open Chords & Easy Major Chords: Obviously, getting a full chord with no fingering is a major plus. Strumming open strings gives a rich, ringing tonic chord – instant gratification! Moreover, by laying one finger across the fretboard, you get another major chord . This simplifies backing rhythm parts. A song that might require complex fingerings in standard can often be played with simple shapes or single-finger bars in an open tuning . Certain chord voicings that are nearly impossible in standard (like a major chord with added drone notes spanning two octaves) become straightforward.

• Rich Resonance and Drones: Open tunings make it easy to use drone notes (open strings that ring throughout a progression). This adds a depth and richness to the music. The guitar almost acts like a bagpipe or sitar, maintaining a tonal drone while you play melodies on top. For example, DADGAD’s multiple D and A strings mean you can fret notes on one or two strings and let the rest hum in sympathy, creating a Celtic drone effect. This resonance can inspire new musical ideas and create an immersive sound for the listener .

• Sliding and Alternate Techniques: As noted, slide guitar is far easier in open tuning . You can also use one-finger slides (even without a slide bar) to shift chords. Additionally, open tunings often facilitate harmonics – natural harmonics at the 5th, 7th, 12th frets of an open tuning will form a chord or part of a scale that’s musically useful (e.g. Open D’s harmonics produce notes of a D major chord and beyond). Some guitarists exploit this for cascading harmonic riffs. Also, percussiveplaying can benefit: hitting open strings percussively in an open tuning yields defined pitches (which can be part of the composition’s harmony) rather than random open notes.

• Inspiration & New Riffs: Perhaps the biggest benefit is how open tunings push you out of familiar habits . Standard tuning often leads guitarists to use the same chord shapes and scale patterns they know. In an open tuning, your muscle memory is reset – you discover new chord shapes by exploration. This can lead to composing fresh progressions that you wouldn’t have thought of in standard. Many guitarists report that alternate tunings inspire creativity, and songs “fall out of the guitar” in surprising ways. The MasterClass article notes that while shapes may not feel intuitive at first, open tuning “has inspired many guitarists to embrace entirely new types of riffs and chord shapes” .

• Adaptable to Multiple Keys with Capo: If you love an open tuning’s sound but want a different key, a capo can transpose the open tuning easily. For instance, Open G tuning capoed at 2nd fret becomes effectively Open A (A major chord sounds when open). Keith Richards often plays in Open G but capos to suit the song’s key. Similarly, Open D capo 2 is Open E (common in blues). This way you keep the benefits of the tuning’s shapes and drones, but adjust the key without retraining fingers or overly stressing strings (open A tuning achieved directly by tuning can strain strings, so many use Open G + capo 2 instead ).

Famous Examples: Open tunings have been used in countless classic songs:

• Open G: Keith Richards uses Open G on Rolling Stones hits like “Brown Sugar” and “Honky Tonk Women” (often played with 5 strings: X–G–D–G–B–D). Blues-rock guitarists from Robert Johnson to Muddy Waters used Open G (or Open A, which is the same tuning raised a whole step) for slide – Johnson’s “Walkin’ Blues” and many others are in an open tuning. Even acoustic rock songs like “Fearless” by Pink Floyd employed Open G for rich ringing chords.

• Open D / Open E: Open D (D–A–D–F♯–A–D) has a huge legacy. Folk singer Joni Mitchell used Open D and variants for songs like “Big Yellow Taxi”. Blues legend Elmore James played “Dust My Broom” in Open D or Open E (Open E is just Open D transposed up a whole tone). Bob Dylan’s “Oxford Town” is in Open D. Derek Trucks and Duane Allmanoften used Open E for slide guitar excellence (e.g., Allman on “Statesboro Blues”). Open D also appears in songs like “The Cave” by Mumford & Sons for its resonant quality.

• Open C: This very low tuning (C–G–C–G–C–E) gives a haunting, deep sound. Led Zeppelin’s “Friends” is in an open C tuning (actually C–A–C–G–C–E, a variant) . Soundgarden’s “Burden in My Hand” is famously in Open C (C–G–C–G–G–E, a slight variation where two strings are close in pitch). These songs use the droning low C to great effect. Many modern fingerstyle players like Andy McKee use Open C or related tunings for percussive guitar pieces (e.g., “Drifting” uses a variant of Open C). Open C is popular in acoustic circles for solo pieces because it sounds so full – but it does demand heavy strings to keep the guitar from buzzing due to the low tuning.

• DADGAD: Although technically not a major or minor chord, DADGAD is worth mentioning among open/modal tunings due to its popularity. Used in “Kashmir” by Led Zeppelin (inspired by guitarist Davey Graham’s introduction of the tuning to British folk) , DADGAD has become synonymous with Celtic guitar music. Artists like Pierre Bensusanhave practically made it their standard tuning. It provides a mystical droning D chord with a suspended fourth (G) that can easily go to G major or D major/minor. The drones (D–A) across multiple octaves in DADGAD give it “killer drone potential,” as one guitarist put it – you have three Ds and two As ringing, which is great for modal melodies .

• Other Open Tunings: Open A (E–A–E–A–C♯–E) was used by blues players (often by capoing Open G at 2nd fret to avoid string strain). For instance, Robert Johnson’s “Cross Road Blues” is often played in Open A. Open F or Open F♯were occasionally used by guitarists like Lowell George (Little Feat) or in Hawaiian slack key traditions. Open D minorwas used by delta bluesman Skip James (giving eerie minor-key songs like “Devil Got My Woman”). Rock band Pearl Jam even uses open tunings; Stone Gossard used an open G5 tuning (with no third) on songs like “Daughter.”

Table 2 below lists some popular open tunings and their characteristics:

Table 2: Common Open Tunings (6-string)

(Open tunings are numerous – guitarists experiment with variations to suit particular songs. Joni Mitchell alone used unique tunings like Open Gm7, open Dmaj7, etc., often tailored to her vocal range and chord needs.)

Other Alternate Tunings and Innovations

Beyond the well-trodden drop and open tunings, guitarists have explored a variety of other alternate tunings to achieve specific goals. Here we cover a few notable ones: down-tuned standard tunings, hybrid/modal tunings, Nashville tuning, and a brief mention of less common experimental tunings.

Down-Tuned Standard (Whole-Step or Half-Step Down)

One of the simplest alternate tunings is to lower all strings by the same interval. E♭ Standard (also called half-step down or “D♯ standard”) means tuning to E♭–A♭–D♭–G♭–B♭–E♭ (every string one semitone flat). D Standard is one whole step down: D–G–C–F–A–D. Because the relative tuning intervals remain identical to standard, you can play all the same shapes and patterns – they will just sound lower in pitch . The primary effect is a change in timbre and key. Guitars tuned down often sound a bit “heavier” or warmer, and string tension is slightly reduced, which can make bending strings easier and vibrato “chewier.” Players also down-tune to accommodate vocal ranges; many singers find songs easier to sing a half-step or whole-step down from standard.

Uses and Benefits: E♭ tuning became extremely popular in rock and blues. Jimi Hendrix almost always tuned to E♭ – if you listen to Hendrix recordings, they’re a half-step lower than concert pitch. This made it easier for him to sing in his baritone-ish range and facilitated bends (the looser strings allowed huge bends and vibrato, as in his soloing style). Stevie Ray Vaughan followed suit, using E♭ tuning for both vocal comfort and a fatter tone (Stevie also used very thick strings, so the half-step slack helped). In the late ’80s hair metal scene, many bands (Guns N’ Roses, for example) tuned down a half-step; Guns N’ Roses’ iconic “Sweet Child o’ Mine” is in E♭ standard – Slash’s opening riff is actually sounding in D♭ major despite being played as if in D major positions. E♭ gave these bands a slight edge in depth while still keeping things bright enough for soaring lead guitar. It’s considered a “good compromise between heavy and bright” – you get a chunkier riff sound without sacrificing too much top-end. It also spares the guitarist from the extended setup changes of more drastic tunings. Countless rock songs are in E♭: Van Halen (almost all early Van Halen songs are E♭ standard), Motley Crüe, Smashing Pumpkins (“Cherub Rock”, “Today”, etc.), Green Day (many songs are a half-step down), and even Metallica on some live renditions or later songs.

D standard (a whole step down) is common in heavier rock and old-school metal. Early Black Sabbath often effectively was in C♯ standard (1½ steps down) by their third album – Tony Iommi used ultra-low tunings to reduce string tension on his injured fingers, inadvertently pioneering that dark sludge sound. Metallica’s “Sad But True” is in D standard (which gave it extra heft). Slayer and Pantera tuned down to D standard for a number of songs in the ’80s and ’90s, sitting between standard and drop tunings in terms of technique (all chords shapes same, just sounding lower). Many modern metal bands that aren’t using 7-strings will use D standard or lower. For example, Children of Bodom and some death metal bands use D. It’s also used outside metal: some folk guitarists tune to D standard to better accompany instruments like fiddles or to get a deeper voice (and then capo up as needed).

Benefits: The major benefit is preservation of fingerings – you lose nothing in terms of fretboard knowledge. If you can play it in standard, you can play it in D standard the exact same way; it will just sound a whole tone lower. So it’s a very accessible alternate tuning. Another benefit is the reduced string tension which can make playability easier (bends, vibrato, and even fretting barre chords can feel smoother). It also can impart a different tonal quality – some describe down-tuned standard guitars as “looser” or “woodier” in tone. As one article put it, E♭ standard “sounds a little heavier than standard tuning” while still using lighter gauge strings for ease .

Challenges: There’s not much technical challenge here, aside from the guitar setup considerations (heavier strings or adjusting intonation if you plan to stay down-tuned). The main thing is ensemble playing: if one guitar is in E♭ standard and another in E standard, they will clash unless one is transposing. Typically, entire bands adopt the same detuning. (For instance, all of Guns N’ Roses are tuned down in concert.) If you’re jamming with others, all need to be aware if you’re down-tuned; otherwise, you’ll be a semitone off. Another challenge is that some beginners might get confused seeing different note names (everything changes by one note: E becomes E♭, etc.), but intermediate players can handle it.

Finally, down-tuning too far on a normal guitar might require going to heavier strings or even a baritone guitar. There’s a practical limit on a standard-scale guitar (25.5” or 24.75”) with typical strings – go much below C standard and it starts getting really floppy. At extreme lows like drop A or B standard, many players opt for a baritone guitar (longer scale length) or a 7/8-string to maintain clarity. For six-string context, E♭, D, C♯, C are all fairly common ranges with appropriate string gauges.

Modal and Other Specialized Tunings (DADGAD, etc.)

We’ve touched on DADGAD, which sits between open and drop categories. It’s often called D suspended or modaltuning. When strummed open, DADGAD gives a Dsus4 chord (no 3rd) . This neutrality is powerful: it doesn’t force a major or minor feel, so the guitarist can choose to emphasize F♯ notes (making it sound like D major) or F natural (D minor) in melodies, all while the open strings drone a D5 or Dsus atmosphere. DADGAD became popular in British and Celtic folk music thanks to Davey Graham in the 1960s . From there, Martin Carthy, Pierre Bensusan, Richard Thompson and others used it for its bagpipe-like drone. It’s also found in rock – aside from Zeppelin’s “Kashmir”, The Beatles’“Dear Prudence” actually combined drop and modal: it’s in Drop D with the high E dropped to D as well (D–A–D–G–B–D, often called Double Drop D, which is a Dsus2 chord open) – not DADGAD, but similar idea of an open chord with suspended tone.

Other modal tunings include Orkney tuning (CGDGCD) which is essentially an Open Csus2 chord; this is used in Celtic guitar as well. These tunings often favor a particular scale or mode. For instance, CGDGCD is great for playing in C major or G Mixolydian. Open fifth tunings (like CGCGCE used by some modern players) remove the third altogether from the open strings, giving just roots and fifths – then the player can create major or minor nuances with fingering.

Nashville Tuning: Nashville tuning is a unique case; it’s not an alternate tuning in terms of pitch class (the open strings are still E A D G B E notes), but it revoices the guitar by using the octave-up strings from a 12-string set on the lower four strings. In Nashville tuning, the 6th string is tuned up to E3 (normally the 6th string E2 one octave lower), the 5th to A3, 4th to D4, 3rd to G4, while the top 2nd (B3) and 1st (E4) remain the same . The result is that the guitar sounds much higher and chimier – it’s as if the “high octave” strings of a 12-string guitar are played in isolation . Chords fingered the same way yield a sparkling, almost mandolin-like version. Nashville tuning is great for studio layering: a common technique is to double a regular guitar part with a Nashville-tuned guitar, and together they mimic a 12-string guitar (without actually needing a 12-string). This was used on many country recordings (hence the name Nashville). For example, it’s said that The Rolling Stones’ “Wild Horses” features a Nashville-tuned guitar alongside a regular acoustic, creating a gorgeous shimmer in the intro. Benefits: You don’t have to change your playing technique at all to get a new sound – you fret chords as usual. The benefit is purely sonic: more clarity, less bass. It’s useful when you want a guitar part to sit higher in the mix, almost like a 12-string or a bouzouki. Songwriters also use Nashville tuning on one guitar and standard on another to differentiate sections or to make a solo acoustic arrangement sound like two guitars (bass notes from one, high from the other). Challenges: You must restring the guitar with special strings (typically the high octave strings from a 12-string set). A standard 6th string cannot be tuned an octave up to E3 without breaking; instead, you’d use something like a 0.026 plain or wound string tuned to E3. Setting up a guitar for Nashville might require adjusting intonation slightly for the thinner strings on the lower positions. Also, by itself, a Nashville-tuned guitar has no bass – it can sound a bit thin if played solo for rhythm. It really shines in accompaniment or recording contexts .

Other Experimental Tunings: Some guitarists have pushed alternate tunings in very different directions for theoretical or technical reasons:

• All Fourths Tuning (E–A–D–G–C–F): This tuning removes the major third interval between G and B of standard, making every interval a perfect fourth. The idea is to have uniformity – any chord shape or scale pattern is shifted by the same fret distance on all string sets. Jazz guitarist Stanley Jordan and others have used all-fourths. The benefit is systematic fretboard logic; the challenge is you lose the convenient open chord shapes and the high E (now F) so sheet music fingerings change.

• Augmented Fourth Tuning / Tritone tuning: (e.g., C–F♯–C–F♯–C–F♯) is very rare, but some avant-garde players like Glenn Branca in his guitar symphonies used unusual tunings to get drones or dissonances.

• Major Thirds Tuning: (C–E–G♯–C–E–G♯) which repeats every three strings, allowing closed-form chord shapes (any major or minor chord can be played with a span of 4 frets), championed by jazz guitarist Ralph Patt. This requires an adjusted technique and often a 7-string guitar to cover range.

• New Standard Tuning (NST): Robert Fripp of King Crimson popularized C–G–D–A–E–G, a tuning combining perfect fifths and a minor third. It extends range (C is quite low, G quite high) and was intended to explore new chordal possibilities.

These more radical tunings are mostly of interest to advanced theorists or those seeking a very distinct sound. They are not common in mainstream music, but worth noting as part of the universe of alternate tunings.

Transitioning Between Tunings and Integration into Your Toolkit

Exploring alternate tunings is exciting, but it also means dealing with practical issues: switching tunings, keeping your instrument in check, and mentally managing multiple tuning systems. Here are some tips for transitioning between tunings and making the most of them:

• Use a Quality Tuner and Mark Your Setlists: When changing tunings, especially on stage or in studio, a reliable chromatic tuner is essential for speed and accuracy. Clip-on tuners or pedal tuners can save time when you drop or raise strings. If your performance involves multiple tunings, plan your setlist to minimize retuning mid-set. Group songs by tuning, or have a second (or third) guitar on hand each pre-tuned to the required alternate tuning. Many performing guitarists have one guitar in standard, one in Open G, one in DADGAD, etc., to avoid onstage retune delays. If that’s not possible, use interludes or banter while retuning and write down which tuning each song uses on your setlist (it’s easy to forget under pressure).

• Gradual Retuning and String Care: When downtuning or uptuning significantly, do it gradually and double-check other strings. Big changes in one string’s tension (like dropping from standard E down to C) can slightly shift the neck and knock other strings out of tune. You might need to touch up the tuning on all strings after a major retune. Also, constantly retuning strings back and forth can fatigue them faster. If you plan to toggle the same guitar between tunings often, be prepared for more frequent string changes (the metal experiences more stress). For extreme alternate tunings, consider dedicating a guitar to that tuning – it allows you to optimize the setup (nut slots, action, intonation) for that tuning and reduces wear from constant change.

• Optimize String Gauges: As discussed earlier, string gauge is important. If you only drop one string a whole step (Drop D), your standard set will likely handle it fine. But if you frequently tune down a whole step or more on all strings, think about using a thicker string set (e.g., moving from .009s to .010s or .011s) to retain tension . For tunings like Open C or Drop B, heavy gauges (.012s or specialized baritone sets) might be necessary to get a tight feel and good tone. Conversely, tunings that require raising strings (Open A or Open E) might benefit from slightly lighter gauges on the strings being tuned up, to avoid breakage. Many acoustic players who use DADGAD or open D will use medium or heavy gauge sets for a solid tone in the lower tuning. Electric players in metal often use “skinny top, heavy bottom” string sets for drop tunings – the low strings are thicker to handle the drop, while the high strings remain bend-friendly for leads.

• Guitar Setup Considerations: When you change tunings, especially lowering, the neck tension changes. If you plan on staying in a new tuning long-term, a setup (truss rod adjustment, intonation check, action) is recommended. Lower tunings reduce neck tension, possibly causing the neck to bow back a bit (resulting in fret buzz). Minor truss rod loosening can compensate for that. Also, intonation points will shift slightly with different tension; checking intonation at the 12th fret for the new tuning ensures you’re in tune up the neck. If you alternate tunings only briefly, it’s not crucial to redo setup each time, but be aware extremely low tunings on a guitar set for standard might intonate a bit off – good tuners that show cents can help you adjust on the fly. Additionally, if using floating tremolo systems (like a Floyd Rose vibrato bridge), retuning one string will throw off all others due to the balance of spring tension. This makes alternate tunings a nightmare on those guitars. It’s best to avoid alternate tunings on a floating bridge guitar unless you block the bridge or set it to dive-only. Fixed-bridge or hardtail guitars are far more tuning-change-friendly.

• Learn the Fretboard Anew (but Find References): When you first dive into an alternate tuning, take time to map out key notes. Locate where the octaves are, where a simple major scale falls, etc. Familiarize yourself with common chord shapes in that tuning – there are resources and charts available for chords in Open D, Open G, DADGAD, etc. Keep a cheat sheet of a few useful voicings for I, IV, V, vi chords in that tuning to get you started. Over time, you’ll internalize it just like standard. A trick: compare the tuning to standard via offsets. For example, in Open D, you might note “the 3rd string is down a half step from standard, 2nd is same as standard B, 1st is down a whole step from standard E”, etc. This can help translate some of your scale knowledge (e.g., any note on 2nd string is same as it would be in standard; the 1st string note is two frets lower than it would be in standard, etc.). Joni Mitchell’s tuning notation (like calling standard “E55545”) encapsulates these intervals – you could adopt a similar system for your own understanding.

• Use Capos and Partial Capos Creatively: Capos can help manage tunings. As mentioned, instead of tuning to Open A (which puts a lot of tension on strings), one can tune to Open G (a safer tuning) and capo at 2nd fret . This achieves the same pitches as Open A. Similarly, you can treat a drop tuning with a capo to shift keys. If you love a riff in Drop D but need it in F, you could capo the Drop D guitar at 3rd fret and effectively get “Drop F” (really F–C–F–A♯–D–G tuned). Partial capos (capos that cover only some strings) can emulate certain alternate tunings without fully retuning. For example, there’s a common partial-capo configuration that presses the top 5 strings at the second fret but leaves the low E open – this effectively creates a Drop E tuning that sounds like E–B–E–A–C♯–F♯ (which is like Open A add9). Some guitarists use partial capos to get drone effects similar to alternate tunings while keeping standard tuning on the uncapoed strings. This is an advanced but useful technique if you want the effect without dedicating a guitar to that tuning.

• Practice Switching Mental Gears: Going from one tuning to another is a bit like switching between speaking two languages. At first, your brain might stumble – you try to play a familiar lick from standard and it comes out wrong in open G. With time, you’ll compartmentalize the tunings. A tip is to practice songs in one tuning exclusively in a session, rather than constantly switching back and forth, to really get in the mindset. Some players even label their fretboard (with painter’s tape dots behind the neck, for example) for alternate tunings, marking where the root notes are, until they’re comfortable. Recording yourself improvising in a new tuning can also accelerate learning; you’ll hear what works and what sounds off, and you can refer back to cool things you accidentally stumbled upon.

• Beware of Transcription and Tabs: If you learn songs from tabs or sheet music, make sure you know what tuning the song is in. A tab written for Open C will be impossible to play correctly in standard tuning and vice versa. Many tab books indicate the tuning at the top. Pay attention so you don’t drive yourself crazy wondering why the fingering doesn’t match the sound. Conversely, when you write your own songs in alternate tunings, notate the tuning on your lyric sheet or notation for future reference. It’s surprisingly easy to forget which odd tuning you used when you come back to a song months later.

• Maintain a Reference of Your Tunings: As you explore multiple tunings, it helps to keep a list or journal. Write down each tuning and perhaps songs or riffs you play in it. This way, you have a go-to index. There are also mobile apps for alternate tunings that provide tuning notes and even chord charts. Over time, you might have several favorites (say, E♭ standard for jamming blues rock, Drop D for rock riffs, Open G for Stones-y stuff, Open D for slide, DADGAD for Celtic moods, etc.). Knowing what “tools” are at your disposal can inspire you – stuck writing in standard? Try composing in one of your alternate tunings to see if it sparks a new idea.

• Guitar Hardware Solutions: If you frequently need to change tunings within a performance, you might consider hardware solutions. The D-Tuna device (popularized by Eddie Van Halen) attaches to a Floyd Rose tremolo and allows instant drop from E to D on the low string with a lever flip – useful for toggling Drop D quickly on a locking trem guitar. Digital solutions like the Digitech Drop pedal can electronically lower your pitch by semitones, meaning you could stay in standard physically but sound in drop C, etc., at the press of a pedal. Similarly, the Line 6 Variax guitars or some modern multi-effects can retune your output digitally. These tools have limitations (some latency or artifact and you lose the natural feel of different tension), but they are options if you need maximum flexibility without swapping guitars. Still, many purists prefer the authentic retuning for the feel and resonance.

Finally, listen and learn from others: Many artists share their experiences with alternate tunings in interviews or tutorials. For instance, Pierre Bensusan’s writings on DADGAD or Martin Simpson’s tutorials on DADGAD and CGCGCD tunings provide insight into fingerings and approaches. Keith Richards has demonstrated his Open G techniques in guitar mags. There’s a wealth of knowledge out there to help you shortcut the learning process for each tuning.
