Pitch

The pitch of a note is how "high" or "low" it sounds - if a mouse squeak is high - and a cow's moo is low :)

On the piano, low notes are to the left, higher to the right.

On sheet music, the pitch is alphabetical from A to G as you climb the lines and spaces - see note reading.

Sometimes extra symbols are added to change the pitch of notes:

 (#) - sharp - raise note a semitone
 (b) - flat - lower note a semitone
