About Low A (D tuning) tuning
Compared with Standard (GCEA), Low A (D tuning) moves 4 strings. Some strings go up and others go down, so the total tension stays close to Standard (GCEA) while the shape of the fretboard changes completely.
| String | Standard (GCEA) | Low A (D tuning) | Change |
|---|---|---|---|
| 1 | G4 | A3 | down 10 semitones |
| 2 | C4 | D4 | up 2 semitones |
| 3 | E4 | F#4 | up 2 semitones |
| 4 | A4 | B4 | up 2 semitones |
Played open, the strings sound A-D-F#-B – from A3 at the bottom to B4 at the top, a span of 1 octave and 2 semitones. Step by step across the neck the intervals are a fourth, a major third, a fourth, and that is what decides how chord shapes fall under the hand.
Left open, the strings together spell D6. That is a by-product of how the intervals are laid out rather than the point of the tuning, but it does mean some chords need very few fingers here. See D6 shapes in this tuning →
