'''73afdo''' ([[AFDO|arithmetic frequency division of the octave]]), or '''73odo''' ([[otonal division]] of the octave), divides the octave into 73 parts of 1/73 each. It is a superset of [[72afdo]] and a subset of [[74afdo]]. As a scale it may be known as [[Harmonic mode|mode 73 of the harmonic series]] or the [[Overtone scale #Over-n scales|Over-73]] scale.

Harmonics 73–146
Prime factorization 73 (prime)
Dual sharp fifth 110/73 (709.842c)
Dual flat fifth 109/73 (694.032c)

The harmonics 73–146 (also harmonic series segment 73::146 or harmonic series mode 73) are a scale that consists of harmonics 73 through 146 (73:74:…:146) and repeats at the octave. Used as a tuning system, it is also called 73afdo.
