How to tune from Standard to C Standard
Every string moves by the same amount: lower 4 semitones.
| String | Standard | C Standard | Change |
|---|---|---|---|
| 6 | E2 | C2 | Lower 4 semitones |
| 5 | A2 | F2 | Lower 4 semitones |
| 4 | D3 | B♭2 | Lower 4 semitones |
| 3 | G3 | E♭3 | Lower 4 semitones |
| 2 | B3 | G3 | Lower 4 semitones |
| 1 | E4 | C4 | Lower 4 semitones |
Tuning this far down makes the low strings loose. Thicker strings (a heavier gauge) keep the tension, tone and tuning stable.
