How do instruments make sounds?

We have been exploring how different types of instruments make sounds. We have looked at how the sound wave is first produced, how you can change the pitch of an instrument and how the instrument amplifies sound. For instance, in a guitar the sound chamber amplifies the sound and you can make the pitch higher by placing your finger on the string (making chords) or by using the tuners to tighten the strings.

We have had a look at guitars, ukeleles, drums, xylophones, harmoniums, and today Hamish's base group were lucky enough to explore a cello. Thanks for bringing it in Jane and spending some time with us. We've also done some research about how electric instruments work.
