It is not easy to learn a new song. First, a slug must find the sheet music and learn it backward and forward. A slug must rehearse the song over and over again until the notes are raw. Creative chord patterns must be found for improvisation during solos. A slug must learn how to hold two mallets with one tail and play the vibraphone with deadly accuracy or the slug might hit a "clam" and get a sour look from the conductor during a performance.....In the midst of all of this rehearsal, a visit from Mr. Canopener can be extremely distracting indeed! Mr Canopener must be kept at bay during the entire learning process. Music can be fun, but it can also be quite dangerous!
