60afdo

60afdo (arithmetic frequency division of the octave), or 60afdo (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 and is highly useful. It is a highly composite AFDO.
