The work is designed to be highly variable, using a system of cards, each of which contain imagery and symbols that are re-imagined into music spontaneously by the performer. The creation of the piece was a symbiotic process between composer and performer, as the score and notation system was designed specifically with Sid’s own compositional language in mind. The piece balances a sense of consistency and structure with a space for play and exploration. Because of this, even though the cards provide a meticulously designed foundation, they allow for significant freedom in the interpretation of the work’s possible pathways.
