SILENCE – the unwilled sounds of the environment, unmasked by composer's intention or performer's activity, are at the heart of each of Cage's compositions since even before the famous “silent” composition 4'33" of 1952.  Used expressively in Nocturne and rhythmically (if sparingly) in Six Melodies, silence becomes the ever-present backdrop to the isolated pitches of OnelO and phrases of Eight Whiskus, and is incorporated into the MATERIAL of Two6 from which the PERFORMER fills the TIME BRACKETS.
