Different drawing of musical notes and rest?

Each note or rest determines the amount of beats in for a note or rest. The time signature of a song consists of two numbers, the top number represents how many beats in a measure, and the bottom number represents how many beats a whole note gets.

In 4/4 timing (4/4 being the time signature) a whole note/rest gets four beats and a measure consists of four beats. Therefore:

Half note/rest- Two Beats

Quarter note/rest- One beat

Eighth note/rest- Half of a beat

Sixteenth note/rest- Quarter of a beat

and so on to 32nd, 64th, etc.

Another coming time signature includes 2/2 (cut time) where a whole note/rest gets two beats and there are two beats in a measure. Therefore:

Half note/rest- One Beat

Quarter note/rest- Half of a beat

Eighth note/rest- Quarter of a beat

Etc.

Other common time signatures include 3/4 (three beats to a measure), 2/4, and 6/8. Follow the same process in deriving the number of beats in a note or rest.
