Compose a piece using only real world sounds. The piece must have an obvious structure - some parts should be repeated, for example.The piece should last between 1 minute 30 and 3 minutes.

Take a few sounds, record them into the computer either directly using the microphone, or via the minidisc recorder.

Decide on your story e.g. the piece could be about the humdrum nature of the school week, so you could illustrate each day in sound, making every day get gradually more distorted. The transformations will be achieved using the audio editor, by applying various effects.

You could use some of the sounds you recorded in lesson 2.
