Pat: To put it simply, it is to use two hands to shoot, one photo and one close, it is called a beat. The tempo of the music is determined according to the requirements of the music. For example, when the required speed of a piece of music is 60 beats per minute, then each beat occupies one-sixtieth of a minute, that is, one beat per second.

A beat, also called a unit beat, is the basis of music and is represented by a designated note. That is, using a variety of different notes, such as half notes, quarter notes, eighth notes, etc. Beats are also divided into half beats, 4 beats, etc., which represent the duration of the beat.

The difference between one beat and two beats is that when the time value of the beat is determined, for example, a quarter note is equivalent to one beat, an eighth note is equivalent to a half beat, a whole note is equivalent to 4 beats, and a half note is equivalent to 4 beats. Equivalent to two beats and so on.
