Notes: In the musical system, the single note with the longest duration is marked by an oval Fu Tou, which is called "whole note", which is called "whole note" in Chinese. Think of this note as "unit 1" in mathematics, and divide it several times, and other notes will appear.

Beat:

In the case of 4/4, the whole note =4 beats, the half note =2 beats, the quarter note = 1 beat, the eighth note = half beat, and the sixteenth note = quarter beat.

Extended data:

Single beats with the same unit beat value but different beats are combined in a bar, which is called mixed beat.

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.
