Project: A triple concerto for piano, percussion and computer with chamber orchestra arranged in four groups each of which contains strings, woodwinds and brass. Initially the composer develops the particular language of pitch and rhythm for the piece, to be followed by the composing of a group of individual "musics" based on this language. The work is approximately twenty minutes long and continuous. The structure emerges from a consideration of the textural interaction of the various musics. As he has done in previous works which make use of the computer, the composer develops the musical materials and structure of the work away from the computer, referring to taped examples of computer instruments developed in advance.
