About D Standard tuning
Compared with Standard (EADG), D Standard moves 4 strings. Every change is downward, the largest by 2 semitones, so the instrument sits at lower tension than in Standard (EADG).
| String | Standard (EADG) | D Standard | Change |
|---|---|---|---|
| 1 | E1 | D1 | down 2 semitones |
| 2 | A1 | G1 | down 2 semitones |
| 3 | D2 | C2 | down 2 semitones |
| 4 | G2 | F2 | down 2 semitones |
Played open, the strings sound D-G-C-F – from D1 at the bottom to F2 at the top, a span of 1 octave and 3 semitones. Step by step across the neck the intervals are a fourth, a fourth, a fourth, and that is what decides how chord shapes fall under the hand.
The drop is small enough that a standard set handles it. If the lowest string starts to rattle against the frets, one step up in gauge fixes it.
