About this piece

Piece for solo cello commissioned by Spain's Centro Nacional de Difusión Musical for the Festival de Música Española de Cádiz (2020/21 season) and premiered by cellist Kathleen Balfe. It takes as its subject the Sibyls, the prophetesses of Greek and Roman myth, whom the composer sees as a rare historical sign of respect for women's intelligence. Built from a series of sequences, it relies on sudden changes of speed, mood and character, with ideas that can vanish as quickly as they appear and return across sections in layered strands of time.
