What is Drop C tuning?

Drop C is C G C F A D, low to high. One way to understand it is D-standard tuning with the sixth string lowered one additional whole step from D to C. Compared with standard tuning, strings 5 through 1 are one whole step lower and the sixth string is two whole steps lower.

How to tune from standard

  1. Lower every string one whole step to D G C F A D.
  2. Lower the sixth string again, from D2 to C2.
  3. Recheck strings 5 through 1 after the large tension change.
  4. Pluck the low C with moderate force and center the meter after the initial attack.

How Drop C changes chord shapes

The three lowest strings are C, G, and C, so one-finger power chords work across them. Strings 5 through 1 keep the same interval relationships as standard tuning but sound a whole step lower. The low sixth string has a different relationship and requires Drop-C-specific scale and chord patterns.

String gauge and setup

Drop C removes enough tension that a light standard set can feel loose and may buzz. Players who stay in Drop C often use heavier strings, but a gauge change can affect the nut slots, neck relief, action, and intonation. Make permanent changes gradually or ask a qualified repair technician for a setup.

  • Do not judge pitch during the sharp initial attack of a heavily picked low string.
  • Check intonation after choosing a permanent string gauge.
  • Return to pitch slowly when tuning back up to avoid overshooting.
