From Create Your Own Story

"Okay you bees" you say, "time to make some honey".

You look on your stand and find that there are a few pieces on your stand. Which should you do first?

• Rehearse Rimsky-Korsakov's song about the Middle East
• Rehearse that Beethoven symphony with the people singing in it
• Rehearse John Cage's 4'33"
