Xylophone

HOW

1. Hit some xylophone tiles with a hammer. Explore how pitch depends on the length of the tile.
2. Find out how the tone varies depending on where you hit a particular tile.

WHY

The xylophone belongs to the group of selfsounding instruments – the so-called idiophones. The struck tile vibrates, resulting in a sound wave. Its length depends on the size of the tile. The shorter the tile, the higher the pitch.
