Programme Note

Contrary Motion, composed in 1969, is a work for solo organ in which pedal points add a functional harmony (A minor) and there is something faintly Bach-ian about its stern, rigorous counterpoint. Contrary Motion was written in what Glass calls "open form" — it never really ends, it just stops. The expanding figures upon which it is constructed could, theoretically, continue augmenting forever. Should an interpreter care to take it that far, a performance lasting hours, even days, would be possible.
