Harmonica<br />
A harmonica is made of metal and it has a metal comb<br />
inside. There are 10 holes and when you blow in them, it<br />
makes a sound. When you blow on the 1 it makes a low<br />
sound and when you blow on the 10 it makes a high<br />
sound. The high sound hole is smaller and the low sound<br />
hole is bigger.<br />
