Tune to C G C F A D for a lower, heavier register with the sixth string dropped relative to the other five. This page loads the complete tuner in Drop C mode.
Drop C is useful for heavy rhythm parts because it preserves the simple low-string power-chord shape of a drop tuning while moving the entire guitar below Drop D. Clean passages also gain a darker register, but familiar standard-tuning chord shapes will sound a whole step lower on the upper five strings.
This setup is substantially lower than standard, so many players use a heavier string set and a setup that accounts for the reduced tension. Strings that are too light can feel unstable, sound unfocused, or buzz before they reach pitch. Make large tuning changes gradually rather than dropping every string at once.
Bring each string near its target, then make a second and third pass. Lowering all six strings changes the total pull on the neck and bridge, so strings tuned early in the process often drift as the others move.
The open sixth string at C2 should sit exactly one octave below the open third string at C3. The low C-G-C group should sound stable as a fifth plus an octave. If those notes pulse against one another, recheck the low C and middle C separately.
The upper five strings retain the same interval pattern as standard tuning but sound one whole step lower. The sixth string is lowered an additional whole step, creating the dropped C-G-C foundation used for broad one-finger power chords.
