As a small boy, already a composer, Peter Cowdrey loved listening to the dawn chorus, but was deeply frustrated at its inaccessibility - too fast, too high - and resolutely resistant to being shoehorned into what his upbringing defined as music. After spending a substantial part of his childhood turning himself into an ornithologist, Peter is delighted that recent technology has come to his rescue, making it possible to crack the hidden codes of birdsong. He is on a mission to share them with the rest of the world, especially children. Other interests include site specific composition. More information can be found at Opera Unlimited, The Conference of Birds, and in this article from The Guardian. His compositions can be heard on his soundcloud page. CDs of his work can be bought here.
• Liz Cowdrey is enchanted by birdsong's elusive higher vibrations…She has begun to use spectrographs to deepen her musical journeys into magical sounds, finding out just what goes on from one note to the next. An international violinist dedicated to spreading the gypsy spirit through violin playing, Liz recreates the essence of birdsong through style and gesture as a learning tool both in preparation for performance and in educational work.
