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 the beat is a relative concept of time. For example, when the specified speed of music is 60 beats per minute, the time occupied by each beat is one second, and the half beat is 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.
