For guitars with six strings, every major-third tuning

chords. By repeating open-string notes and by having uniform intervals between strings, major-thirds tuning simplifies learning by beginners. These features also facilitate advanced guitarists'

precisely the aim of jazz guitarist
Ralph Patt
Ralph Oliver Patt (5 December 1929 – 6 October 2010) was an American jazz guitarist who introduced major-thirds tuning. Patt's tuning simplified the learning of the fretboard and chords by beginners and improvisation by advanced guitarists. ...
when he began popularizing major-thirds tuning between 1963 and 1964.
Avoiding standard tuning's irregular intervals
In standard tuning, the successive open-strings mix two types of intervals, four perfect-fourths and the major third between the G and B strings:
:E2–A2–D3–''G3''–''B3''–E4.
Only major thirds occur as open-string intervals for major-thirds tuning, which is also called "''major-third'' tuning",
"''all-thirds'' tuning",
and "''M3'' tuning".
The most viable M3 tunings are:
:*E2-G#2-C3-E3-G#3-C4
:*F2-A2-C#3-F3-A3-C#4
:*F#2-A#2-D3-F#3-A#3-D4
:*G2-B2-D#3-G3-B3-D#4
:*G#2-C3-E3-G#3-C4-E4
All of these tunings reduce the overall range of the instrument a bit: the first takes a M3 off the top of the range, and the last takes a M3 off the bottom of the range. One popular M3 tuning has the open strings:
:G2–C3–E3–G3–C4–E4,
which some guitarists have applied to the top six strings of a
seven string guitar
The seven-string guitar adds one additional string to the more common six-string guitar, commonly used to extend the bass range (usually a low B) or also to extend the treble range.
The additional string is added in one of two different ways: by ...

The middle tunings are a compromise, each losing a note or two off both the top and the bottom of the range. For example, for six-string guitars, the M3 tuning:
:F2–A2–D3–F3–A3–D4
loses the two lowest semitones on the low-E string and the two highest semitones from the high-E string in standard tuning; it can use string sets for standard tuning.

For fundamental-chord fingerings, major-thirds tuning's simplicity and consistency are not shared by standard tuning, whose seventh-chord fingering is discussed at the end of this section.
Repetition
Each major-thirds tuning
repeats its open-notes after every two strings, which results in two copies of the three open-strings' notes, each in a different octave. This repetition again simplifies the learning of chords and improvisation.
This advantage is not shared by two popular regular-tunings,

is especially simple in major-thirds tuning. Chords are inverted simply by raising one or two notes three strings. The raised notes are played with the same finger as the original notes. Thus, major and minor chords are played on two frets in M3 tuning even when they are inverted. In contrast, inversions of chords in standard tuning require three fingers on a span of four frets,
in standard tuning, the shape of inversions depends on the involvement of the irregular major-third.

musical intervals are the same for each pair of consecutive strings. Other regular tunings include

In contrast, chords cannot be shifted around the fretboard in standard tuning, which requires four chord-shapes for the major chords: There are separate fingerings for chords having

Shifting chords: Vertical and diagonal
The repetition of the major-thirds tuning enables notes and chords to be raised one octave by being ''vertically'' shifted by three strings.
Notes and chords may be shifted ''diagonally'' in major-thirds tuning, by combining a vertical shift of one string with a horizontal shift of four frets:
"Like all regular tunings, chords in the major
third tuning can be moved across the fretboard (ascending or descending a major third for each
string)...."
In standard tuning, playing scales of one octave requires three patterns, which depend on the string of the root note. Chords cannot be shifted diagonally without changing finger-patterns. Standard tuning has four finger-patterns for musical intervals,
four forms for basic major-chords, and three forms for the inversion of the basic major-chords.

. In M3 tunings, the
''augmented'' fifth replaces the ''perfect'' fifth of the major triad, which is used in conventional open-tunings.
For example, the C-augmented triad (C,E,G) has a G in place of the C-major triad's G. (The note G is enharmonically equivalent to A, as noted above.) Consequently, M3 tunings are also called (open) ''augmented-fifth tunings'' (in French "''La guitare #5, majeure quinte augmentée''").

Fingering of seventh chords

By definition, a ''dominant seventh'' is a four-note chord combining a major chord and a

. For example, the C7 seventh chord combines the C-major chord with B. In standard tuning, extending the root-bass C-major chord (C,E,G) to a C7 chord (C, E, G, B) would span six frets (3–8);
such seventh chords "contain some pretty serious stretches in the left hand".
An illustration shows this C7 voicing (C, E, G, B), which would be extremely difficult to play in standard tuning,
besides the
openly voiced C7-chord that is conventional in standard tuning:
This open-position C7 chord is termed a second-inversion C7 drop 2 chord (C, G, B, E), because the second-highest note (C) in the second-inversion C7 chord (G, B, ''C'', E) is lowered by an octave.

Disadvantages
While major thirds tuning confers the numerous advantages detailed above, it also introduces certain disadvantages, as compared to the instrument's standard tuning:
:* M3 tuning decreases the overall range of the guitar (this is why some players eventually resorted to 7- and 8- string instruments, to regain that lost range)
:* M3 simplifies the voicing of chords in
''close harmony'', but it makes certain common voicings in
''open harmony'' more difficult, or even impossible
:* M3 facilitates moving 3- and 4-note chords up or down an octave, but it makes the fingerings for 5- and 6-note multi-octave chords more complex and awkward.
