What is a beat?

Beat is a unit to measure rhythm. In music, a series of beats with certain strength are repeated at fixed intervals. Such as 2/4, 4/4, 3/4 beats, etc.

Beat represents the organization form of fixed unit time value and dynamics law in music. Also known as beat. The cycle of strong beat and weak beat in each bar is called double beat; The cycle of strong beat, weak beat and weak beat is called triple beat. A symbol indicating the time length and quantity of the basic unit beat in each bar is called the time signature. The number above the time signature indicates the number of beats in each bar, and the number below indicates the duration of each beat.

Single beats with the same unit beat value but different beats are combined in a bar, which is called mixed beat. For example, 5/4 is a combination of 2/4+3/4 or 3/4+2/4, 7/8 is a combination of 2/8+2/8+3/8 or 3/8+2/8, and so on.

Chinese folk music calls this beat "banyan tree". What kind is it? A board with three eyes, a board without eyes, a board without eyes and so on. A board or a glance is a shot. Generally speaking, the positions of the board and eyes are equivalent to those of the above-mentioned strong beat and weak beat, but it does not mean that they all conform to the cycle law of strong beat and weak beat.

Extended data:

In music, time is divided into equal basic units, and each unit is called a beat or a beat. The duration of the beat is represented by the duration of the notes. The duration of a beat can be a quarter note (that is, taking a quarter note as a beat), a quarter note (taking a quarter note as a beat) or an eighth note (taking an eighth note as a beat).

The duration of beat is a relative concept of time. For example, when the specified speed of music is 60 beats per minute, each beat takes up one second, and half a beat takes up half a second; When the specified speed is 120 beats per minute, the time for each beat is half a second, half a beat is a quarter of a second, and so on. After the basic time value of the beat is determined, the notes of various time values are associated with the beat.

For example, taking a quarter note as a beat, a whole note is equivalent to four beats, a half note is equivalent to two beats, an eighth note is equivalent to half a beat, and a sixteenth note is equivalent to a quarter beat; If the eighth note is taken as a beat, the whole note is equivalent to eight beats, the second note is four beats, the fourth note is two beats, and the sixteenth note is half beat.
