Yep, you guessed it. This chapter is all about music. Yes, we've already talked about music and musical instruments, but we're going to get into this subject in more detail. For example, you might already know that larger musical intruments tend to produce lower notes, but that isn't always true. A clarinet and a flute are about the same size, but the flute produces much higher notes. Why? Stay tuned (a little music humor there) and you'll find out. So, all togther now, "Climb every mountain..."
