Staff (US) or stave (UK)
Crotchet is a quarter note (16) so quaver, eight note (8)
Ledger Lines
Vertical bar lines divide the staff into measures
Bass Cleft used for percussion and trombones
Staccato (notes sharply detatched)
An interval
The music repeat sign (looks like a thick bar at the start of the line with two dots on the side like this |: )
Rest
A fermata (half a cirlce with a dot in it)
The tie (a curved line connecting two or more notes)
Hope this helped.
