Cage's One8 was composed for cellist Michael Bach, an artist who had a very important place in Cage's late work. Its duration of 43'30" makes an oblique reference to Cage's groundbreaking 4'33" and it is constructed of 53 time brackets with single sounds to be played on 1, 2, 3, or 4 strings. These time brackets tell the player when to begin and end each section (each section often containing a single note). Durations, dynamics and bow positions are free.<br> <br>Michael Bach is noted for the revival of the "curved-bow" for the cello. Typical in the baroque era, the curved bow allows the cellist to make contact with up to four strings simultaneously, permitting the performer to play chords on the cello.
