This article explores the spatial identities of the flautists in playing Kaija Saariaho's music with live electronics, particularly reverberation and harmonisation. The varying spatial position of the flautists are theorised mainly via two approaches: that of ‘local/field' concepts by Simon Emmerson, and through the philosophy of narrative identity developed by Paul Ricoeur. The article investigates the flautists' experiences of control over the sound, and especially its most intimate form, direct control, by discussing the relationship between the choices of live flautist and the sound director. The sound result is constantly negotiated by several authorial activities, the contributions of which are closely overlapping and conversing with each other.
