About Drop C tuning

Drop C is D standard with the sixth string dropped an extra step to C — the same one-finger power chord layout as Drop D, but a whole step heavier. It's the definitive tuning of 2000s metal and post-hardcore: crushing lows that still track clearly on a 6-string.

Tune the sixth string down four semitones to C and the rest down two. If you're coming from standard on light strings, expect the low C to need a heavier gauge to stay articulate.

How to tune to Drop C from standard

  1. String 6 (E2): tune down 4 semitones to C2.
  2. String 5 (A2): tune down a whole step to G2.
  3. String 4 (D3): tune down a whole step to C3.
  4. String 3 (G3): tune down a whole step to F3.
  5. String 2 (B3): tune down a whole step to A3.
  6. String 1 (E4): tune down a whole step to D4.

After changing string tension this much, make a second tuning pass — the neck settles slightly and the first strings you tuned will have drifted.

String gauge advice

.011–.056 or a dedicated drop set (.010–.052 with a heavy bottom) keeps the low C tight.
