Repetition

A popular children’s song has repetition

The bell on the bus goes

Ding, ding, ding

The bell on the bus goes

Ding, ding, ding,

all day long.

This can be written using a loop (x3)

The bell on the bus goes

Ding, ding, ding (x3)

The bell on the bus goes

Ding, ding, ding (x1)

all day long.

The words are written once alongside the number of repeats needed
