The length of a beat should be calculated in a relatively balanced manner based on the following concepts:

When a quarter note is one beat, an eighth note is equivalent to half a beat, and a whole note is equivalent to 4 beats. , a half note is equivalent to two beats, while a sixteenth note is equivalent to 1/4 beat.

In other words, there is one quarter note, two eighth notes, and four 16th notes in one beat. For another example, an eighth note is one beat, a quarter note is two beats, a half note is four beats, a whole note is eight beats, and a sixteenth note is half a beat. In this way, when the time value of the beat is determined, various The notes of duration are connected to the beat.

The beat of music refers to the combination of strong beats and weak beats. Specifically, it refers to the total length of notes in each section of the score. Common ones are 1/4, 2/4, 3/4, and 4. /4, 3/8, 6/8, 7/8, 9/8, 12/8 beats, etc. The length of each measure is fixed. The tempo of a piece of music is fixed at the time of composition and will not change. A piece of music can be composed of a combination of several beats.
