Microtonal music

One of the composition techniques of Western modernist music.

Microtonal music, or microtonal music for short, microtonal is an interval smaller than a semitone. In some works, the composer also used a small amount of microtonal as decoration to add some changes to the traditional pitch. Most of them use their own notation to represent microtonal notes on traditional staffs. Bartok Bellah once marked arrows directly next to the notes to indicate the rise and fall of the microtonal. Bloch drew diagonal lines between notes to represent the rise and fall of microtones. Alois Haba and Penderecki created new symbols from the deformation of sharp and flat marks, as microtonal sharp and flat marks. The C sound is represented by 0, and in an octave, the sound is represented by a consecutive number. For example, the chromatic scale can be represented by 0~11, and the quarter-tone scale can be represented by 0~23.
