How to tune from Standard to Drop C♯
Lower every string a half step, then lower string 6 a further whole step.
| String | Standard | Drop C♯ | Change |
|---|---|---|---|
| 6 | E2 | C♯2 | Lower 3 semitones |
| 5 | A2 | G♯2 | Lower a half step |
| 4 | D3 | C♯3 | Lower a half step |
| 3 | G3 | F♯3 | Lower a half step |
| 2 | B3 | A♯3 | Lower a half step |
| 1 | E4 | D♯4 | Lower a half step |
Tuning this far down makes the low strings loose. Thicker strings (a heavier gauge) keep the tension, tone and tuning stable.
