This sonata was designed to showcase both flute and piano as equal partners. The first movement uses continuous semiquavers to weave a chromatic melodic web, while the third (and final) movement uses the same device to create a driving rhythmic pulse. The central slow movement contrasts the flute's sinuous melodic ability against static ringing qualities of the piano.

This work was commissioned by 2MBS-FM Radio (Sydney) with financial assistance from the Performing Arts Board of the Australia Council. It was written for and dedicated to Geoffrey Collins.
