60afdo (arithmetic frequency division of the octave), or 60odo (otonal division of the octave), divides the octave into sixty parts of 1/60 each. As a scale it may be known as mode 60 of the harmonic series or the Over-60 scale. Due to 60 being 2 x 2 × 3 × 5, this afdo contains many common 5-limit intervals.

60 is a highly composite afdo, containing within it 1, 2, 3, 4, 5, 6, 10, 12, 15, 20 and 30 afdo.
