After learning a song about a woodpecker, the girls chose instruments from the WOODS family to represent the woodpecker tapping on the tree. Claves, rhythm sticks, woodblocks, and temple blocks have a hollow, wooden timbre. When asked "Why do these instruments sound like a woodpecker?", one student replied, "Because they are all made out of wood and it makes a big, wooden, tapping sound. Like a woodpecker tapping on the trunk of a tree."
