Apollo

John Pennington’s Apollo (1968) is aleatoric (“chance”) music. The aleatoric element depends on the players, not the composer or conductor. In most cases, each player is free to choose the actual pitches s/he will play, and the moment s/he will play them, within the limitations imposed by his part and the conductor. Except for the flute solo, this work does not consist of melody or harmony, but a series of sound events. The task of the conductor is to shape and control these events into a coordinated and unified whole. (Source: published score)
