source: TEDEducation 2013-07-18

Like an actor's script, a sheet of music instructs a musician on what to play (the pitch) and when to play it (the rhythm). Sheet music may look complicated, but once you've gotten the hang of a few simple elements like notes, bars and clefs, you're ready to rock. Tim Hansen hits the instrumental basics you need to read music.
