Sounds can be made by twanging a string or an elastic band, blowing down a pipe, banging something together, and scraping or shaking something. There are three families of musical instruments - string, wind and percussion. When a string is plucked on an instrument such as a guitar, the vibration is passed into the air and you hear a sound. Blowing into panpipes or a horn makes the air inside the pipes vibrate. Bongos and other percussion instruments produce vibrations when you bang them.

Useful as an introduction to how sounds are made through vibration and could lead on to an activity where children make their own musical instruments using household items. Children could then use these home-made instruments to do a class performance. This could also be used within a Music lesson introducing the children to the types of instruments.
