How to read musical notes: Types of Rests
Music also has rests, which indicate silent beats - time when no notes are played. They're counted in the same way as notes, and correspond to the notes they represent.
The Whole rest
Looks like a dark rectangle attached to a bar line, facing downwards (1 shown).
The Half rest
Looks like a dark rectangle attached to a bar line, facing upwards (2 shown).
The Quarter rest
Looks like a squiggly line (4 shown).
The Eighth rest
Looks like a slanted line with a dot (8 shown).
The Sixteenth rest
Looks like a slanted line with a double dot (16 shown).
These continue on to thirty-second and sixty-fourth rests (with three and four dots, respectively).
