Apologies for this very newbie-type question, but I was wondering about 5-string tunings. With my 4-string, I play in Dropped C (FCGC), so what would I do for a 5 string?

Any help would be much appreciated.

you could tune to(from low to high) GCGCF, or you could play the C on the first fret of the low B, G on the third fret of the E, higher C on third fret A, F on third fret D.

any help?
