Noun
circle of fifths (plural circles of fifths)
Alternative form of cycle of fifths
The sharp side of the circle of fifths can be read off directly from the white keys on a piano's octave (by making the appropriate jumps): Do–So–Re–La–Mi–Ti–Fi. Also, the flat side of the circle of fifths can almost be read off entirely from the black keys on a piano's octave (with the exception of Fa): Do–Fa–Te–Me–Le–Ra–Se.
