« Piece for Flute and Voice » was composed for Rebecca Simpson-Litke, a flutist and a soprano. The piece explores various combinations and juxtapositions of singing and playing; the performer is asked to sing and play both simultaneously and separately, and to make transitions between the two timbres. The early stages of the piece emphasize the similarities between the sound of the voice and that of the flute, highlighting their common origins in the human breath. Over the course of the piece, however, a process of differentiation occurs. Although they are borne of the same esprit, the two modes of sound production explore and develop their unique characteristics, each finding its individual personality.
