Four-three beats: There are three beats per measure with quarter notes as one beat. The duration of each beat is determined by the tempo of the music.

Beat, an organizational form in music that represents fixed unit duration and intensity patterns. Also called beat. The cycle of strong beats and weak beats in each section is called two beats; the cycle of strong beats, weak beats, and weak beats is called triple beats. The notation that represents the duration and number of the basic unit beats in each section is called the time signature. The upper number of the time signature indicates the number of beats in each measure, and the lower number indicates the duration of each beat.

Extended information:

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

The duration of a beat is a relative concept of time. For example, when the specified speed of the music is 60 beats per minute, each beat takes one second, and a half beat is one-half second; when At a specified speed of 120 beats per minute, each beat is half a second, a half beat is a quarter of a second, and so on. After the basic duration of the beat is determined, the notes of various durations are linked to the beat.

For example, when a quarter note is used as one 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 four beats. One beat; if an eighth note is used as a beat, a whole note is equivalent to eight beats, a half note is four beats, a quarter note is two beats, and a sixteenth note is half a beat.
