Steve Halfyard is a performer specialising in music theatre and extended vocal technique. She studied music at City University before going on to complete a PhD on Music Theatre at the University of Birmingham. Due to the largely fortuitous fact that both these music departments specialise in electroacoustic composition, she has worked with many electroacoustic composers, in particular Joseph Hyde, Simon Emmerson, and Simon Hall. She has collaborated extensively with composer Ed Bennett, and was a founding member of his ensemble, Decibel. She performed an extensive range of contemporary music by composers such as Berio, Berberian, Andriessen, Knussen, Birtwistle, Reich, Wishart and Stockhausen, who she worked with on both the British productions of Sternklang in 1988 and 1992.
She is currently the Director of Studies (Undergraduate) at Birmingham Conservatoire, where she teaches courses in twentieth century music, performance practice and film music.
