Drop C Tuner Online
Tune your guitar by ear with your microphone, free.
Drop C delivers crushing, low-slung riffs — the whole guitar drops a whole step and the sixth string drops further still, giving metal and metalcore their signature heavy chug. Tune down below to get there.
About Drop C Tuning
Drop C tuning is C G C F A D (low to high). It is built like Drop D but a whole step lower: first the entire guitar is tuned down a whole step to D-standard, then the lowest string is dropped a further whole step. The result keeps Drop D's one-finger power-chord shape on the bottom three strings while sitting two semitones deeper, for a thick, aggressive low end.
To reach Drop C from standard EADGBE, derive each string: the low E drops two whole steps to C, the A drops a whole step to G, the D drops a whole step to C, the G drops a whole step to F, the B drops a whole step to A, and the high E drops a whole step to D. In other words every string comes down a whole step except the lowest, which comes down two. Once tuned, barring the bottom three strings at any fret gives an instant power chord — perfect for fast, palm-muted riffing.
The slack strings and deep root make Drop C a cornerstone of modern heavy guitar.
