caption_attribution_description: English: Open chords for all perfect-fourths tuning (P4 tuning) for six-string guitar E-A-D-G-C-F in the key of C major: Major triads (C major, F major, and G major) and major-minor seventh with dominant function (dominant seventh G7).
context_page_description: Among alternative tunings for the guitar, all-fourths tuning is a regular tuning. 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. 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.
  Among regular tunings, this all-fourths tuning best approximates the standard tuning.
  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. 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 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. Jazz musician Stanley Jordan plays guitar in all-fourths tuning; he has stated that all-fourths tuning "simplifies the fingerboard, making it logical".

  Among all regular tunings, all-fourths tuning E-A-D-G-C-F is the best approximation of standard tuning, which is more popular. An advantage of standard tuning is that it has many six-string chords, unlike all-fourths tuning. All-fourths tuning is traditionally used for the bass guitar; it is also used for the bajo sexto.
  Allan Holdsworth stated that if he were to learn the guitar again he would tune it in all-fourths.
