Introduction to beats

Beat, an organizational form in a piece of music that expresses 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 three 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. For example, 2/4 means one beat with a quarter note, and there are two beats in each measure. The actual time of the value in the time signature should depend on the tempo of the music.
Among different beat types, those with only one strong beat per measure are called single beats. For example, 2/4 and 2/8 are single 2 beats, and 3/4 and 3/8 are single 3 beats. Each measure has one downbeat and two downbeats, which is called a compound beat. For example, 4/4 and 6/8 are complex 2 beats, and 9/8 and 9/16 are complex 3 beats.
Single beats with the same unit beat value but different beat numbers are combined within a section, which is called a mixed beat. For example, 5/4 is a combination of 2/4+3/4 or 3/4+2/4, and 7/8 is a combination of 2/8+2/8+3/8 or 3/8+2/8+2. /8 combination and so on.
Chinese folk music calls the beat Banyan. Its types include one-eye, one-three, one-eye, no-eye, etc. A board or a glance is a shot. Generally speaking, the position of the board and eye is equivalent to the above-mentioned strong and weak beat positions, but it does not always mean that it conforms to the law of strong and weak beat cycles.
