This short piano prelude is an algorithmic composition, the third in the Drums and Different Cannons series, mapping chaotic equations into pitch and time. The first two were tape works, but this is the first designed for a live performer. In this case the equation is the Torus equation x" = K sin(x). To me the interest lies in the similar but non-identical repeating patterns, and sudden changes that form cannons.
This version is realised via Rosegarden, Csound and samples.
The piece is named in honour of Connie, a pianist who loves to play John Cage, and whose playing inspired(?) me to create this piece.
