A quarter tone is a pitch halfway between the usual notes of a chromatic scale or an interval about half as wide (orally, or logarithmically) as a semitone, which itself is half a whole tone. Quarter tones divide the octave by 50 cents each, and have 24 different pitches.
The actual notes in a fully implemented quarter-comma scale (requiring about 31 keys per octave instead of only 12) would be consonant, like all of the uncolored intervals: The dissonance is the consequence of replacing the correct quarter-comma notes with wrong notes that happen to be assigned to the same key on the 12 tone keyboard. As ...
The modern Arab tone system, or system of musical tuning, is based upon the theoretical division of the octave into twenty-four equal divisions or 24-tone equal temperament, the distance between each successive note being a quarter tone (50 cents). Each tone has its own name not repeated in different octaves, unlike systems featuring octave ...

In Germany, Austria, and Czechoslovakia in the 1910s and 1920s the usual term continued to be Viertelton-Musik (quarter tone music [36] [page needed]), and the type of intervallic structure found in such music was called the Vierteltonsystem, [37] [38] which was (in the mentioned region) regarded as the main term for referring to music with ...
The values indicated by the scale at the left are deviations in cents with respect to equal temperament. Quarter-comma meantone, which tempers each of the twelve perfect fifths by 1 / 4 of a syntonic comma, is the best known type of meantone temperament, and the term meantone temperament is often
Comparison between tunings: Pythagorean, equal-tempered, quarter-comma meantone, and others.For each, the common origin is arbitrarily chosen as C. The degrees are arranged in the order or the cycle of fifths; as in each of these tunings except just intonation all fifths are of the same size, the tunings appear as straight lines, the slope indicating the relative tempering with respect to ...
