In music, there are not only the height and length of sound, but also the pause of sound. The symbol indicating the sound pause is called a rest and marked with "0". In layman's terms, it is a symbol without sound.

Rests and notes are basically the same, and there are six kinds. However, in general, the added horizontal lines are directly replaced by 0. Every time a 0 is added, the duration of a four-point rest is increased.

Rest is a symbol used to record the interval duration of different long and short sounds. The ratio of each larger sound value to its nearest smaller sound value is 2 1. The whole note equals two binary notes, the whole rest equals two binary rests, and so on.

Extended data

The use of rest can create different emotional expressions in musical phrases. The naming of rest is mainly based on the length of pause, which is divided into multiple full rest, full rest, binary rest, four-point rest, eight-point rest, sixteen-point rest, thirty-two-point rest and sixty-four-point rest.

The rest can also be added with an additional point to adjust the length of the music pause, and named as the original rest name, with the words "additional point" in front.

Expressing the length of music requires a relatively fixed concept of time. It is the basic reference measure of length, that is, a quarter note is a beat. The concept of beat here is the unit of relative time measurement. There is no limit to the length of a beat, which can be 1 second, 2 seconds or half a second.
