Droppe C tuning is an alternative guitar tuning style in which the lowest (sixth) string is tuned down two tones ("dropped") to C and the rest of the strings are tuned down one tone, thus making the overall tuning CGCFAD from low to high. Although popularly referred to as "Drop C", CGCFAD tuning is not in fact "Drop C" tuning; a "drop" tuning refers only to the dropping of the tuning of the lowest string; thus "Drop C" tuning is actually CADGBE and the tuning referred to is actually "Drop D, tuned down one whole step (tone)." Throughout the rest of this article, what is referred to as drop C is CGCFAD, or drop D tuned down one whole step.
