Alwynne Pritchard was born in Glasgow in 1968 and as a teenager began having composition lessons with her father, Gwyn Pritchard. She then studied with Robert Saxton at the Guildhall School of Music, and later with Melanie Daiken, Justin Connolly and Michael Finnissy at the Royal Academy of Music, where she was awarded many prizes for her work. In 1997 she was awarded a research scholarship by the University of Bristol and in 2003 received a PhD in composition. In September 2008 Alwynne became the Artistic Director of the Borealis Festival (www.borealisfestival.no) in Bergen Norway, where she now lives.
In 2002 the BBC Symphony Orchestra gave the first performance of Alwynne’s orchestral work Critical Mass, and in March 2007 her piano concerto Map of the Moon was premiered by Nicolas Hodges and the BBC Scottish Symphony Orchestra. Decoy, created at the Heinrich Strobel Stiftung, Freiburg, in 2005 for the Donaueschingen Musiktage, was awarded the special prize given by the Foundation Ton Bruynèl, STEIM and the Foundation GAUDEAMUS.
