A FuniChar D-616 guitar with a Drop D tuning. It has an unusual additional fretboard that extends onto the headstock. Most guitarists obtain a Drop D tuning by detuning the low E string a tone down.
This article contains a list of guitar tunings that supplements the article guitar tunings. In particular, this list contains more examples of open and regular tunings, which are discussed in the article on guitar tunings. In addition, this list also notes dropped tunings.
This open C tuning is used by William Ackerman for his "Townsend Shuffle" and by John Fahey for his tribute to Mississippi John Hurt. This tuning is also commonly used by John Butler on his 12-string guitar.[1] This tuning is used on most work by Devin Townsend in his solo work as well as his work with Strapping Young Lad. When playing on a 7-string guitar, he would have a low G as the lowest string to complete the fifth. David Wilcox also recorded his most famous songs, "Eye of the Hurricane" and "Rusty Old American Dream", both from How Did You Find Me Here, in this tuning, as well as "New World", "Show the Way", "Hold It Up to the Light", and his cover of "It's the Same Old Song" from Big Horizon, and "Mango" from East Asheville Hardware.
This open-C tuning gives the initial harmonic series when a C-string is struck.[4]
The C-C-G-C-E-G tuning uses the harmonic sequence (overtones) of the note C. When an open-note C-string is struck, its harmonic sequence begins with the notes (C,C,G,C,E,G,B♭,C).[3][4]
This overtone-series tuning was modified by Mick Ralphs, who used a high C rather than the high G for "Can't Get Enough" on Bad Company. Ralphs said, "It needs the open C to have that ring," and "it never really sounds right in standard tuning".[5]
This tuning is the same as Open D but tuned a half-step down. It is used by Alice In Chains on the songs "Over Now", "Nothin' Song", and "Shame in You"; by Guns N' Roses on the song "Bad Obsession"; and by Switchfoot on the song "Daisy".
Alternatively: C-G-D-G-B-D (used by Big Wreck on multiple songs, most notably "Inhale" and "Mistake"—They downtune it a half step[11]—and by David Wilcox on "It's Almost Time", "Just a Vehicle", "Distant Water", "Golden Day", and his covers of "The Kid" and "Missing You ." Also used by Andrew Peterson on his song "Faith to be Strong" and by Macseal on multiple songs.)
Dobro Open G: G-B-D-G-B-D (occasionally adopted for ordinary guitar, but requires lighter fifth and sixth strings).
The following open-tunings use a minor third, and give a minor chord with open strings. To avoid the relatively cumbersome designation "open D minor", "open C minor", such tunings are sometimes called "cross-note tunings". The term also expresses the fact that, compared to Major chord open tunings, by fretting the lowered string at the first fret, it is possible to produce a major chord very easily.[14]
In modal tunings, the strings are tuned to form a chord which is not definitively minor or major. These tunings may facilitate very easy chords and unique sounds when the open strings are used as drones. Often these tunings form a suspended chord on the open strings. A well known user of modal tunings is Sonic Youth.
Bsus4: B-F♯-B-E-F♯-B (DADGAD but three notes (1-1/2 steps) lower, a main tuning of Sevendust, who have used it since Animosity)
Badd9: B-F♯-C♯-F♯-B-D♯, Used by Devin Townsend on "Bastard", a minor variation is used by Alter Bridge on the song "This Side of Fate" tuned B-F#-C#-F#-B-D
Csus2: C-G-C-G-C-D (first five strings equivalent to Double-C tuning for the banjo, believed to have been used by David Wilcox on "Let Them In" from Home Again (for the First Time), though even he isn't entirely sure)
Csus4+9: C-G-C-F-C-D (used by Martin Simpson in "We Are All Heroes", and by David Wilcox on "Come Away to Sea" from The Nightshift Watchman with the high string raised to E)
Low C: C-G-D-G-A-D (used by David Wilcox on "High Hill", "Covert War", "Chet Baker's Unsung Swan Song", "Break in the Cup", "Show Me the Key", "Silent Prayer", and "Leaving You")
Dsus2: D-A-D-E-A-D (used by David Wilcox on "How Did You Find Me Here")
Dsus4: D-A-D-G-A-D (devised by British guitarist Davey Graham[21] in the late 1950s, associated with French acoustic guitarist Pierre Bensusan,[22] and used by Jimmy Page of Led Zeppelin for a number of songs including "Kashmir" and "Black Mountain Side"; also used by David Wilcox on multiple songs, occasionally tuning half a step down)
Esus2: E-B-E-F♯-B-E (used by My Bloody Valentine in "Only Shallow" and by John Mayer in "Something's Missing," "Wherever You Go," "Heart So Heavy," and "In Your Atmosphere").
Esus4: E-B-E-A-B-E, E-A-B-E-B-E (the latter used by Jars of Clay on their debut album Jars of Clay)
E7sus4: E-A-D-E-B-E (used by Ed Sheeran in "Tenerife Sea.")
EEEEBE a.k.a. "Bruce Palmer Modal Tuning," as named and used by Stephen Stills in "Suite: Judy Blue Eyes where Stills uses this tuning while the other guitar is in standard tuning.[23])
In the minor-thirds tuning, every interval between successive strings is a minor third. In the minor-thirds tuning beginning with C, the open strings contain the notes (C, D♯, F♯) of the diminished C chord.[28]
Major-thirds tuning is a regular tuning in which the musical intervals between successive strings are each major thirds.[29][30][31] Unlike all-fourths and all-fifths tuning, major-thirds tuning repeats its octave after three strings, which again simplifies the learning of chords and improvisation.[32]
Neighboring the standard tuning is the major-thirds tuning that has the open strings
This tuning is like that of the lowest four strings in standard tuning.[34][35] Jazz musician Stanley Jordan plays guitar in all-fourths tuning; he has stated that all-fourths tuning "simplifies the fingerboard, making it logical".[36]
All-fifths tuning is a tuning in intervals of perfect fifths like that of a mandolin, cello or violin; other names include "perfect fifths" and "fifths".[38] It has a wide range, thus it requires an appropriate range of string gauges. A high b' string has been recently developed by Octave4Plus gauged at .006 which is considerable thinner than most guitar strings on the market, but under low tension to prevent breakage.
Ostrich tuning is a tuning where all strings are tuned to the same note over two or three octaves,[39] creating an intense, choruseddrone and interesting fingering potential.
Drop tunings lower the sixth string, dropping the lowest E string of the standard tuning. Some drop tunings also lower the fifth string (the A-note in standard-tuning). A drop one tuning lowers the pitch by one full step.
Some lower tunings may call for a baritone guitar to more easily maintain high string tension and a rich tone. Others can be achieved using a capo and/or a partial capo.
Drop E – E-B-e-A-C♯-F♯ / E-B-e-A-D♭-G♭/ Five full steps down from Drop D, or one full step up from Drop D1. Another Variation can be mixed with a Drop A as follows: E-A-e-a-D-G-B-e modeled on an 8 string or E-A-e-a-D-F#-B/E-A-e-a-D-Gb-B on a seven-string guitar, Used by Starset on Horizons, Loathe (E-A-e-a-D-F♯/G♭), Humanity's Last Breath (E-B-e-A-G♯/A♭-a) and To The Grave/Body Prison guitarist Tom Cadden(E-A-e-A-D-G-B). The guitarist from Humanitys Last Breath (Buster Odeholm) has the 2 plain strings 1 note away from each other (Ab-a) in order to do dissonant chords without using finger stretching chords and also can be used sith the digitech whammy pedal live to introduce interesting harmonics & FX. Usually 27" or 28" Baritones are used for 6 string Drop E applications.
Drop D♯/Drop E♭ – D♯-A♯-d♯-G♯-C-F / E♭-B♭-e♭-A♭-C-F Five and one half steps down from Drop D, or one half step up from Drop D1. This can also be a Drop D# standard octave variant tuning modeled on an 8 string D#-G#-d#-g#-C#-F#-A#-d#. Gravemind uses an altered version of Drop D# (which is a 6-string Drop A# with the low D#) on their album Conduit. Meshuggah also used Drop D# for some of their songs (e.g.: "Stengah," "Shed").
Drop D1 – D-A-d-G-B-E Six full steps (one octave) down from Drop D. 8 string example; D-A-d-a-d-G-B-E. Black Tongue uses this tuning. Meshuggah also used it for "Obsidian" and "This Spiteful Snake".
Drop C♯1/Drop D♭1 – C♯-G♯-c♯-F♯-A♯-D♯ / D♭-A♭-D♭-G♭-B♭-E♭ Six full steps (one octave) down from Drop C♯/Drop D♭, Used by Loathe (C#-A-E-a-D-F♯/G♭)
Drop C1 – C-G-c-F-A-D Six full steps (one octave) down from Drop C.
Drop C♯/Drop D♭ in standard variation – C♯-A-D-G-B-E Standard tuning but with the 6th string lowered one and a half steps. Used by Sevendust tuned one and a half-step down (which goes as: A#-F#-B-E-G#-C#) on some songs from Home through Alpha.
Drop C in standard variation – C-A-D-G-B-E Standard tuning but with the 6th string lowered two whole steps. Used by Mark Tremonti on the song "My Champion" (tuned down a half-step; Myles is in Open F# tuning) as well as Sevendust on the song "Mountain" tuned down one and a half steps. (which goes A-F#-B-E-G#-C#) Also used by John Mayer on the song "Neon", and by Chino Moreno of Deftones on some songs such as "Swerve City" , "Leathers" and "Hearts/Wires", tuned down a full step (A#-G-C-F-A-D), This variation was also used by Periphery on "Totla Mad" from their Self-Titled album and "Frak the Gods" on "Icarus EP".
Drop B-E – B-E-D-G-b-e Standard tuning with the 6th and 5th string lowered two and a half steps down. Used by Tool in the songs "Parabol" and "Parabola".
Drop A in standard variation – A-a-D-G-B-E: The 6th string is dropped to A while the other strings retain their standard tuning. Used by Helmet on "Biscuits for Smut", Foo Fighters on "Stacked Actors", Avenged Sevenfold on "G", Opeth on the song "Sorceress", and the Melvins on "Boris". Used by Every Time I Die on the songs "Indian Giver", "Fear and Trembling" and "Nothing Visible; Ocean Empty". A 7-string version of this tuning is used by Muse on their song "Citizen Erased", tuned A-a-D-d-G-B-E, as well as on Supremacy, which features a standard six-string guitar. Sevendust uses this tuning a half-step down on "Home". Periphery uses this tuning, but tuned 1 step down on "Reptile", The band Architects also use this tuning, but tuned one and a half step down, since their album Lost Forever // Lost Together released in 2014 and Wage War tuned 2 steps down on several songs[57]
Drop A in D standard variation – A-G-C-F-a-D: Used by Mastodon on most of their first album (Remission) and on some songs on other albums. Also utilized by Nothing More and Periphery (primarily on more recent material) Also used on occasion by Black Label Society, who previously tuned it a half-step up, which Alter Bridge also utilizes on some of their songs such as "Broken Wings", "Come to Life", "I Know it Hurts", "Still Remains", "Breath Again", and "All Hope is Gone." Creed, Architects, all use this tuning tuned a half-step down on their songs "Bread of Shame", "Early Grave" respectively. Danish industrial metal band Raunchy used this tuning tuned one and a half-step down (F#-E-A-D-f#-B) on the song "Dim the Lights and Run" from the album A Discord Electric.
Drop G in C standard variation – G-F-A#-D#-g-C: Used by Bring Me the Horizon on a few songs from their album Suicide Season, "Blacklist" from There Is A Hell and "heavy metal" from amo,[58]Wage War also utilize this tuning on several songs on their first three albums, such as "The River" and "Spineless" off their album Blueprints.
Derived from standard EADGBE, all the strings are tuned lower by the same interval, thus providing the same chord positions transposed to a lower key. Lower tunings are popular among rock and heavy metal bands. The reason for tuning down below standard pitch is usually either to accommodate a singer's vocal range or to get a deeper/heavier sound.[59]
G♯/A♭ tuning – G♯-C♯-F♯-B-D♯-G♯ / A♭-D♭-G♭-B-E♭-A♭ Four full steps down from standard tuning. Utilized by Cannibal Corpse on some songs. Used by death/doom metal band Encoffination. Also used by Mark Tremonti on the song "In the Deep" (Myles Kennedy uses a 6-string guitar tuned to Drop Db in the song).
G tuning – G-C-F-A♯-D-G / G-C-F-B♭-D-G Four and a half steps down from standard tuning. Used by the doom metal band Warhorse and the brutal death metal band Mortician and the sludge metal project Foreigns.
F♯/G♭ tuning – F♯-B-E-A-C♯-F♯ / G♭-B-E-A-D♭-G♭ Five full steps from standard tuning. Used by the death metal band Disfiguring the Goddess.
F tuning – F-A♯-D♯-G♯-C-F / F-B♭-E♭-A♭-C-F Five and a half steps down from standard tuning. Used by the deathgrind band Maruta, the instrumental doom metal band Bongripper, and the progressive metal band Meshuggah (however the band uses 8-string guitars).
Octave tuning – E-A-D-G-B-E Six full steps (one octave) down from standard tuning. The Low E has the same fundamental frequency as a bass guitar, essentially the same standard tuning as a bass guitar but with a high B and E added to mimic a regular guitar. This tuning is used on the Fender Bass VI and similar instruments. Notably used by John Lennon and George Harrison with the Beatles, Robert Smith of the Cure, Jack Bruce of Cream, and Deftones bassist Sergio Vega on their album Gore. In his early days with Ronnie Hawkins, future Band bassist Rick Danko was also seen with a Fender Bass VI. This is the tuning Earth used on their seminal drone doom album, Earth 2. Also used in some doom metal and sludge metal bands such as Wetlands and Thou.
From standard EADGBE, all the strings are tuned up by the same interval. String tension will be higher. Typically requires thinner gauge strings, particularly the first string which could be as thin as six thousandths of an inch (about the thickness of a single human hair). A capo is typically preferred over these tunings, as they do not increase neck strain, etc. The advantage of these tunings is that they allow an extended upper note range versus a capo used with standard tuning which limits the number of notes that can be played; in some cases, instruo B♭ or E♭ (such as saxophones, which were frequently encountered in early rock and roll music) are more easily played when the accompanying guitar plays chords in the higher tuning. If standard gauge strings are used, the result is often a "brighter" or "tighter" sound; this was a common practice for some bluegrass bands in the 1950s, notably Flatt & Scruggs.
F♯/G♭ tuning – F♯-B-E-A-C♯-F♯ / G♭-B-E-A-D♭-G♭ One full step up from standard. Primary tuning for the band The Chameleons. Johnny Marr also used this tuning extensively with The Smiths. British singer-songwriter Dave Mason also plays in F#. Alex Lifeson of Rush used this tuning on the song "The Big Money". Tremonti uses a variation of this tuning where only the 6th string is raised to F# while the rest of the guitar stays in standard tuning, and then tuning down the whole guitar one and a half steps, on the song "Trust".
G tuning also known as Terz tuning (sometimes spelled "Tierce", "Third", or "Tertz", all of which are acceptable) – G-C-F-A♯-D-G / G-C-F-B♭-D-G One and a half steps up from standard.
G♯/A♭ tuning – G♯-C♯-F♯-B-D♯-G♯ / A♭-D♭-G♭-B-E♭-A♭ Two full steps up from standard.
A tuning – A-D-G-C-E-A Two and a half steps up from standard. This is the standard tuning for the Lapstick travel guitar.
A♯/B♭ – A♯-D♯-G♯-C♯-F-A♯ / B♭-E♭-A♭-D♭-F-B♭ Three full steps up from standard.
Double drop D tuning.Double drop D tuning (listen)
Similar to the dropped tunings, except that both the 1st and 6th strings are dropped one full step.
Double Drop D – D-A-D-G-B-D Standard tuning but with the 1st and 6th strings dropped one full step. Favored by Neil Young. Has also been used by Lamb of God on some of their earlier songs. America used a variation for "Horse with No Name" in which the 5th string is also dropped, to E. It was also used on Led Zeppelin's Going to California
Double Drop C♯/Drop D♭ – C♯-G♯-C♯-F♯-A♯-C♯ / D♭-A♭-D♭-G♭-B♭-D♭/ Same as [Double] Drop D, but every string is dropped one half step. Used by the acoustic rock band Days of the New. Also used by Our Lady Peace on the song "Starseed", as well as Los Angeles based Alternative band Failure on several songs. Also used by Tremonti on the song "Fall Again", as well as Myles Kennedy on the song "Cry a River" (Mark is tuned to Drop C#)
Double Drop C – C-G-C-F-A-C One full step down from Drop D. Used by End and Sevendust on the song "Seasons".
Double Drop B – B-F♯-B-E-G♯-B / B-G♭-B-E-A♭-B/ One and one half steps down from Drop D. Used by Aaron Turner of Isis and used by Sevendust on the song "Separate".
Double Drop A♯/Drop B♭ – A♯-F-A♯-D♯-G-A♯ / B♭-F-B♭-E♭-G-B♭ Two full steps down from Drop D.

Double Drop F♯/Drop G♭ – F♯-C♯-F♯-B-D♯-F♯ / G♭-D♭-G♭-B-E♭-G♭ Four full steps down from Drop D, or two full steps up from Drop D1.
Double Drop F – F-C-F-A♯-D-F / F-C-F-B♭-D-F Four and one half steps down from Drop D, or one and a half steps up from Drop D1.
Double Drop E – E-B-E-A-C♯-E / E-B-E-A-D♭-E Five full steps down from Drop D, or one full step up from Drop D1.
Double Drop D♯/Double Drop E♭ – D♯-A♯-D♯-G♯-C-D♯ / E♭-B♭-E♭-A♭-C-E♭ Five and one half steps down from Drop D, or one half step up from Drop D1.
Double Drop D1 Tuning – D-A-D-G-B-D Six full steps (one octave) down from Double Drop D.
DADGAD was developed by Davey Graham in the early 1960s when he was travelling in Morocco, to more easily play along with Oud music. Among the first to use this tuning were the folk-blues guitarists of the '60s like Bert Jansch, John Renbourn, Martin Carthy, and John Martyn. It was many years later in the 1970s that it became established for accompanists of traditional music, predominantly Scottish and Irish. Due to this popularity it is sometimes referred to as "Celtic" tuning, although this is misleading given its origin and its primary early use in a quite different field of music. Often vocalized as "Dad-Gad", DADGAD it is now common in Celtic music. In rock music, has been used in Led Zeppelin's "Kashmir".[8]Pierre Bensusan is another noted exponent of this tuning. The post-metal group Russian Circles also employ this tuning, and also plays it tuned a half-step down: D♭-A♭-d♭-g♭-a♭-d♭'. Four down-tuned variations are used by the band Sevendust: A Drop C# variation, or C♯-G♯-c♯-f♯-g♯-c♯', Also uses a variation where the lowest string is dropped to G♯ on the song "Chop", A Drop C variation, or 'C-G-c-f-g-c'. (used on the song "Unraveling". Also uses a variation where the lowest string is dropped to G, used on some songs from Kill the Flaw and the song "Life Deceives You"), a Drop B variation, or B'-F♯-B-e-f♯-b, and a Drop A# variation, or A♯'-F-A♯-d♯-f-a♯. Neighboring tunings D-A-d-e-a-e' and C-G-c-d-g-a have been used by Martin Carthy, and D-A-d-a-a-d' was used by Dave Wakeling on the English Beat's 1983 "Save It For Later" and by My Bloody Valentine on the song "Sometimes" from Loveless (1991).
Nicknamed - "Papa-Papa". DADDAD is common in folk music (Irish, Scottish), and for the execution of a rhythm guitar in "heavy" (alternative music) on 6th on the third string at the same time. To reach the tuning from DADGAD, Open D or Open D Minor, the G string is dropped to D so that the 3rd and 4th strings are tuned to the same pitch. DADDAD tuning is sometimes used on Dobro guitars for rock and blues. Notable users of this tuning include Billy McLaughlin and John Butler.
Essentially a cello tuning with the deeper four strings in fifths and the two highest strings in standard guitar tuning. Used on numerous Pavement songs (including Cut Your Hair) and by Foo Fighters on the song "Weenie Beenie".
Mi-composé is a tuning commonly used for rhythm guitar in African popular music forms such as soukous and makossa.[61] It is similar to the standard guitar tuning, except that the d string is raised an entire octave. This is accomplished by replacing the d string with an e' string and tuning it to d'.
This is a tuning favored by the Swedish singer-songwriter José González. He uses this on such songs as "Crosses", "Heartbeats" and "Cycling Trivialities" (capo on second fret). It is similar to the standard guitar tuning, but the low E string is dropped to D and the G string is dropped a half step to F♯/G♭. Also used by artists such as M. Ward, Stephen Malkmus, and Day Wave.
This tuning is used by Tonic in their song Soldier's Daughter with a capo on the 4th fret, Periphery uses this tuning a full step down on the song "Scarlet".
This tuning was made by songwriter/composer Mr.Tom (Rawding) during the creation of an original indie folk instrumental "When You Stand By Me".[62] The tuning is based on the Open D tuning.
A combination of Drop Ab and Drop Db, Used by Mike Mushok on many songs, especially from Dysfunction and Break the Cycle.
Variation:
Gb-Db-Ab-Db-Gb-Bb
The previous tuning with the 6th string an additional step down, used on the song "Price to Play" and for all but one song on the Self-Titled album, these songs are played live on a 7-string with a high Eb due to some leads being tracked in a higher tuning.
The open strings of a guitar can be tuned to microtonal intervals, however microtonal scales cannot easily be played on a conventional guitar because the frets only allow for a chromatic scale of twelve equally spaced pitches, each a semitone apart. (Certain microtonal scales, particularly quarter tones, can be played on a standard guitar solely by adjusting tunings, but the distance between notes on the scale makes it somewhat impractical.) It is possible to play microtonal scales on a fretless guitar, to convert a fretted guitar into a fretless, or to make a custom neck with a specific microtonal fret spacing.
Guitars can also be refretted to a microtonal scale.[63] On many refretted microtonal guitars, the frets are split, so that the tuning of each string is independent from the others. To enable an adjustable microtonal tuning, there exist guitars with frets that can be moved across the fingerboard.[64][65]
Extended techniques such as the 3rd bridge technique, slide guitar and prepared guitar techniques can be used to produce microtonality without severe modification to the instrument.
In his on-line guide to alternative tunings for six-string guitars, William Sethares mentions several that are inspired by instruments other than guitars, for example:
This tuning may also be used with a capo at the third fret to match the common lute pitch: G-c-f-a-d'-g'. This tuning also matches standard vihuela tuning and is often employed in classical guitar transcriptions of music written for those instruments, such as, for instance, "La Canción Del Emperador" and "Diferencias Sobre Guardame Las Vacas" by Renaissance composer Luis de Narváez, or music inspired by this style, such as "Pavanna" and "Bicycle Tune" by John Renbourn.
When the guitar evolved from the renaissance lute in the 18th century it was a five-string instrument (baroque guitar). Today, five-string guitars are common in Brazil, where they are known as guitarra baiana and are typically tuned in 5ths. Schecter Guitar Research produced a production model five-string guitar called the Celloblaster in 1998.[66] A five-string tuning may be necessary in a pinch when a string breaks on a standard six-string (usually the high E) and no replacement is immediately available.
Some basic five-string tunings include:
Standard – E-A-d-g-b The standard tuning, without the top E string attached. Alternative variants are easy from this tuning, but because several chords inherently omit the lowest string, it may leave some chords relatively thin or incomplete with the top string missing (the D chord, for instance, must be fretted 5-4-3-2-3 to include F#, the tone a major third above D).
Baroque guitar standard tuning – a–D–g–b–e The predecessor of today's six-string classical guitar was the five-string baroque guitar tuned as the five high strings of a six-string guitar with the A raised one octave.
High C – E-A-d-g-c' Standard tuning with the B tuned a half step higher to C to emulate a six-string bass guitar, minus the low B. This is an all fourths tuning.
Celloblaster or Guitello – C-G-d-a-e' An all fifths tuning as used on cello or mandolin, extended to five strings. Used by the noise-rock band Lightning Bolt, and by Jeffrey McFarland-Johnson on his Bach Cello Suites album.[67]
Baritone – E-A-d-f♯-b In this tuning, the fourth (G) string is lowered a half-step, thus recreating the intervals between the top five strings, lowered a perfect fourth. Though chords can easily and more fully be played from this tuning, it sometimes results in awkward inversions, a relatively minor problem if the five-string is played in an ensemble with a bass guitar.
E-A-c♯-f♯-b Simulates the top four strings, followed by the second-from-bottom string on top, raised a whole step (the F♯ representing both the top and bottom E). It makes playing in the key of A major easier, though chord fingerings have to be altered unless the strings are rearranged to F♯-B-E-A-C♯.
Open G tuning – G-d-g-b-d' Some slide/bottleneck guitarists omit the bottom E string when playing in open G to have the root note as the tonic. This tuning is used by Keith Richards.
Open E♭5 tuning – E♭-B♭-e♭-b♭-e♭' This is achieved by removing the fourth (G) string, tuning both Es and the B down a half step, and the A and D strings up a half-step. This creates a five-string power chord.
Jacob Collier's "mirrored" tuning – D-A-e-a-d' As explained to the guitarist Paul Davids in a YouTube video [68]. Jacob Collier can be seen and heard playing a custom made acoustic or electric five-string (almost?) any time he plays guitar. He claims that this tuning allows beginners easier access to guitar playing.
Similar to five-string bass guitar tuning, seven-string tuning allows for the extra string a fourth lower than the original sixth string. This allows for the note range of B standard tuning without transposing E standard guitar chords down two and a half steps down. Baritone 7-string guitars are available which features a longer scale-length allowing it to be tuned to a lower range.
Drop D 7-string tuning – D-D-A-d-g-b-e' This is the standard seven-string tuning with the low B string raised to D and lower E string dropped to D. The Drop C variation of this tuning (C-C-G-C-F-A-D) was used by James Hetfield on an ESP 7-String Guitar when Metallica were recording the song "Some Kind Of Monster" from the album St. Anger.
Drop A 7-string tuning – A'-E-A-d-g-b-e' This is the standard seven-string tuning with the low B string dropped to A.
Standard Choro tuning – C-E-A-d-g-b-e' Standard seven-string tuning for Brazilian choro.
Drop D + B 7-string tuning – B'-D-A-d-g-b-e' Standard seven-string tuning with the low E dropped to D, which results in a minor 3rd interval between the two lowest strings of B and D. Used by Ed Sloan of Crossfade. Also used by Animals as Leaders on the song "CAFO". A flat variation of this tuning is used by Periphery on the song "Racecar".
Drop D + A 7-string tuning – A'-D-A-d-g-b-e' Seven-string tuning with the low E string dropped to D and a low A added below. Used extensively by Dir En Grey since the album "Dum Spiro Spero" as well as the song "Obscure" from the album Vulgar. Also used by Stam1na.
Thirds tuning – E-G♯-c-e-g♯-c'-e' Same range as standard six-string. Allows over two full chromatic octaves without changing position, slides or bends.
All fourths tuning – B'-E-A-d-g-c'-f' Expands the major third between the second and third strings, extending range a half step higher.
Russian Tuning – D-G-B-D-g-b-d 6-string Open G tuning with additional 5th B-string. Was a standard tuning for classic 7-string guitars in Russia in the 19th to 20th centuries.

On pedal steel guitar, the most common tunings on double-neck instruments are the extended-chord C6 tuning and E9 tuning, sometimes known as the Texas and Nashville tunings respectively.[76] On a double-neck instrument, the neck nearest the player will normally be some form of C6, and the furthest neck E9.[76]
Necks with 12 or more strings can be used with universal tunings which combine the features of C6 and E9. On a 12-string pedal steel guitar, all 12 strings are tuned and played individually, not as six double courses as on the 12-string guitar.
On a lap steel guitar there may be up to four necks, each tuned differently. The C6 tuning was a common tuning for a six-string lap steel in the 1920s and 1930s.[77]: 131 Tunings with a sixth interval are popular in Western swing and jazz, while tunings containing sevenths are often chosen for blues and rock music.[78]
