In music, the pitch of a note means how high or low the note is Treble Clef for high notes Bass Clef for low notes 2

Accidentals are signs that are put just before a note to tell the musicians to change the pitch Flat Sharp Natural 3

Flat The flat lowers the pitch by a semitone Sharp The sharp raises the pitch by a semitone Natural The natural cancels any previous sign 4

B The pitch goes down from B to B flat B Bb Bb B B Bb B 5

F The pitch goes up from F to F sharp F F# F# F F 6

Natural cancels the flat out B The pitch goes up from B flat to B natural B Bb Bb B B Bb B 7

Natural cancels the sharp out The pitch goes down from F sharp to F natural F F F# F# F F 8

Flat Natural Sharp An accidental lasts until another one on the same line or space cancels it, or until the next bar line 9

The natural sign cancels out the sharp. The pitch goes down from F sharp to F 10

The natural sign cancels out the flat. The B flat goes up one pitch to B 11

The sharp is cancelled out by the bar line. F sharp goes down one pitch to F 12
