John Cage

One 13

'The metamorphosis from RYOANJI to ONE13 occurred during a collaboration between John Cage and myself in July 1992 in New York City. In determining a total of eight intervals for a planned version of RYOANJI for cello, a chance operation produced the result that the third interval should be a unison prime, the interval F#' - F#'. John Cage had not anticipated a unison prime as the result of the chance operation and wanted to pass it over as useless and simply ignore it. That unpredictable prime immediately cast its spell over me. In the two following days I had the opportunity then to convince John Cage of this chance by demonstrating to him twenty different and multiphonic F#' sounds on the cello....On 20 July 1992, John Cage told me that he wanted to transfer the unison prime idea, which now also fascinated him, to further pitches, with the words: '...and this will be One13.'”--
