Sounds can be made by twanging a string, 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.
