In the quarter-tone scale, also called 24-tone equal temperament (24-TET), the quarter tone is 50 cents, or a frequency ratio of 24 √ 2 or approximately 1.0293, and divides the octave into 24 equal steps (equal temperament). In this scale the quarter tone is the smallest step.

A septimal quarter tone (in music) is an interval with the ratio of 36:35, which is the difference between the septimal minor third and the Just minor third, or about 48.77 cents wide. The name derives from the interval being the 7-limit approximation of a quarter tone .

As discussed above, in the quarter-comma meantone temperament, the ratio of a semitone is S = 8 : 5 5 ⁄ 4, the ratio of a tone is T = √ 5 : 2. The tones in the diatonic scale can be divided into pairs of semitones. However, since S 2 is not equal to T, each tone must be composed of a pair of unequal semitones, S, and X:
A sharp-and-a-half, three-quarter-tone sharp, or sesquisharp raises a note by three quarter tones. Although very uncommon, a triple sharp (or ...
