All fourths tuning
| All fourths | |
|---|---|
 The consecutive open notes of all-fourths tuning are spaced apart by five semitones on the chromatic circle, which lists the twelve notes of the octave. | |

Among alternative tunings for the guitar, all-fourths tuning is a regular tuning.[1] In contrast, the standard tuning has one irregularity—a major third between the third and second strings—while having perfect fourths between the other successive strings.[2][3] The standard tuning's irregular major-third is replaced by a perfect fourth in all-fourths tuning, which has the open notes E2-A2-D3-G3-C4-F4.[1][4]
Among regular tunings, this all-fourths tuning best approximates the standard tuning.[5]

In all guitar tunings, the higher-octave version of a chord can be found by translating a chord by twelve frets higher along the fretboard.[6] In every regular tuning, for example in all-fourths tuning, chords and intervals can be moved also diagonally. For all-fourths tuning, all twelve major chords (in the first or open positions) are generated by two chords, the open F major chord and the D major chord. The regularity of chord-patterns reduces the number of finger positions that need to be memorized.[1] Jazz musician Stanley Jordan plays guitar in all-fourths tuning; he has stated that all-fourths tuning "simplifies the fingerboard, making it logical".[7]
Among all regular tunings, all-fourths tuning E-A-D-G-C-F is the best approximation of standard tuning, which is more popular. All-fourths tuning is traditionally used for the bass guitar;[5] it is also used for the bajo sexto.[8]
Allan Holdsworth stated that if he were to learn the guitar again he would tune it in all-fourths.[9][10]
Relation with all-fifths tuning
[edit]All-fourths tuning is closely related to all-fifths tuning. All-fourths tuning is based on the perfect fourth (five semitones), and all-fifths tuning is based on the perfect fifth (seven semitones). The perfect-fifth and perfect-fourth intervals are inversions of one another, and the chords of all-fourth and all-fifths are paired as inverted chords. Consequently, chord charts for all-fifths tunings may be used for left-handed all-fourths tuning.[11]
