A '''arithmetic temperament''' is a type of [[temperament]] which generates a, when period-reduced, arithmetic progression of frequency. This is in contrast to [[regular temperaments]] which generate a geometric progression instead. Arithmetic temperaments are to [[AFS]]s as regular temperaments are to [[ET]]s.

Arithmetic temperaments can "[[temper out]]" commas in a similar way to regular temperaments, but because period reduction is now performed through addition/subtraction rather than multiplication/division, tempering out a [[comma]] means to equate it to 0 (the additive identity) instead of 1 (the multiplicative identity). | |||
The arithmetic equivalent of [[monzos]]s is, in a sense, [https://en.wikipedia.org/wiki/Positional_notation positional notation] systems–monzos represent numbers as a product of the powers of the base elements (primes), whereas positional notation systems represent numbers as a sum of the multiples of the base elements. |
