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.
Sonido 13 is a theory of microtonal music created by the Mexican composer Julián Carrillo around 1900 [1] and described by Nicolas Slonimsky as "the field of sounds smaller than the twelve semitones of the tempered scale."

Microtonal music or microtonality is the music with microtones (also called 'microintervals') used as ornamental inflexions of basically diatonic/chromatic scales or substantial elements of specifically microtonal scales. Some scholars also call 'microtonal' music with intervals which deviate from a semitone of the Western 12-tone equal ...
These etudes bring out connections and resemblances to twelve-tone music as well as various xenharmonic characteristics, reflected in Twelve Microtonal Etudes for Electronic Music Media.
