Extended information:

Different notes represent different durations. Commonly used notes include whole notes, half notes, quarter notes, eighth notes, and sixteenth notes. The durations represented by half notes, quarter notes, eighth notes, and sixteenth notes are 1/2, 1/4, 1/8, and 1/16 of the whole note respectively.

If a note is followed by a dot, the note will be 1/2 longer than its undotted duration.

Whole note: A hollow white note without a stem or tail is called a "whole note". It is the big brother of the note family. The duration of other notes is shorter than it (except for double notes), and it must be based on it. Divide it into two halves.
