Literature and art derive much creative value from ambiguity and its interpretation. In music, ambiguity of function is an acknowledged source of meaning in Western tonal harmony, but digital sound processing and synthesis takes the electroacoustic genre beyond the traditional pitch-duration paradigm of instrumental music, consequently raising many compositional problems of intelligibility, form and meaning. Sound creation tools enabling this new landscape are widespread, but little critical attention has been paid to their affective possibilities. This practice research interrogates the phenomenon of ambiguity as a driver of meaning in electroacoustic music.
