Beat is the basic unit of time in music. It is the regular, steady pulse that you feel when you listen to music. The beat is often created by the percussion instruments, such as the drums or cymbals.
Pulse is the subdivision of the beat. It is the smaller, faster units of time that you feel when you listen to music. The pulse is often created by the melody or harmony instruments, such as the guitar, piano, or violin.
The relationship between beat and pulse can be seen in the following diagram:
```
Beat: |---------------------------------------|
Pulse: | | | | | | | | | | | |
```
In this diagram, the beat is represented by the vertical lines. The pulse is represented by the smaller horizontal lines. As you can see, the pulse is subdivided into smaller units of time.
The beat and pulse are essential elements of music. They help to create the rhythm and flow of music. Without beat and pulse, music would be chaotic and difficult to listen to.
