Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals".It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave.

Four steps make a whole tone. Quarter tones and intervals close to them also occur in a number of other equally tempered tuning systems.
