To mark the 50th anniversary in 2008 of the creation of the BBC Radiophonic Workshop, the programme examines the life and legacy of one of the great pioneers of British electronic music - the Workshop's co-founder Daphne Oram. As a child in the 1930s, Oram dreamed of a way to turn drawn shapes into sound, and she dedicated her life to realising that goal. Her Oramics machine anticipated the synthesiser by more than a decade, and with it she produced a number of internationally-performed works for the cinema, concert hall and theatre. Daphne Oram was among the very first composers of electronic music in Britain and her legacy is the dominance of that soundworld in our culture today.
