The composer discovering the secrets of birdsong
Birdsong is the inspiration for composer Peter Cowdrey's music.
As a child he tried to transcribe birdsong but was frustrated by the speed and complexity of the songs of everyday garden birds.
Now, using a spectrograph to visualise and slow down birdsong, he not only uses it in his music but also works with school children developing lessons that combine music and science.
