Avid readers may remember a recent piece about a Canadian professor who invented The Cloud Harp, an instrument that creates music from the shape of the clouds above it.

On a similar theme, English composer Richard Garrett has written to tell us how he makes music from the changing patterns of the weather as recorded by an electronic weather station.

You can hear some of the music and find out more about Richard’s Weathersongs project by visiting his website: www.weathersongs.org
