John Pennington, composer
John Pennington’s Apollo 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 he will play,
and the moment 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.
