This is a short snare drum piece lasting 16 bars consisting of grade 1 and grade 2 level snare drum rhythms.
The snare drum sheet music focuses on using plenty of dynamics, which are for volume changes in the music.
The dynamics include:
p (piano = soft/quiet)
mf (mezzo forte = medium loud)
f (forte = loud)
< a wide version of this shape is a ‘crescendo’ (gradually getting louder)
> these arrows above the notes are accents, which indicate that you play loud on this note only.
