A '''linear step scale'''{{idiosyncratic}} is a possible generalization of [[equal temperament]]s other than [[MOS scale]]s. The size of the step after a note increases linearly in the form ax+b where x is the index of the note (starting from 0). For example, a 3-tone octave-repeating scale with the step size determined as 10x+285 in [[cents]] would have the step sizes between intervals as 285-295-305- | A '''linear step scale'''{{idiosyncratic}} is a possible generalization of [[equal temperament]]s other than [[MOS scale]]s.

All linear step scales are logically [[harmonotonic tuning]]s (decreasing step sizes for negative slope and increasing step sizes for positive slope). | ||

Most such scales are [[nonoctave]]. The scales which have octaves can have the a in "ax+b" determined by only b and the number of tones: | |||
a = (-2bn + 2b + 2400)/(n^2 - 3n + 2) | |||
Where n represents the number of tones, and all pitches are given in cents. | |||
