'''30afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''30odo''' ([[otonal division]] of the octave), divides the octave into thirty parts of 1/30 each. It is a superset of [[29afdo]] and a subset of [[31afdo]]. As a scale it may be known as [[Harmonic mode|mode 30 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-30]] scale. Since 30 factors into primes as {{nowrap| 2 × 3 × 5 }}, this afdo contains many common [[5-limit]] intervals above its root and is extremely useful for common tonal harmony.
