Music for 18 Musicians

Music for 18 Musicians is approximately 55 minutes long. The first sketches were made for it in May 1974 and it was completed in March 1976. Although its steady pulse and rhythmic energy relate to many of my earlier works, its instrumentation, structure and harmony are new.

As to instrumentation, Music for 18 Musicians is new in the number and distribution of instruments: violin, cello, 2 clarinets doubling bass clarinet, 4 women’s voices, 4 pianos, 3 marimbas, 2 xylophones and metallophone (vibraphone with no motor). All instruments are acoustical. The use of electronics is limited to microphones for voices and some of the instruments.

“There is more harmonic movement in the first 5 minutes of Music for 18 Musicians than in any other complete work of mine to date. Though the movement from chord to chord is often just a re-voicing, inversion or relative minor or major of a previous chord, usually staying within the key signature of three shapes at all times, nevertheless, within these limits harmonic movement plays a more important role in this piece than in any other I have written.

Rhythmically, there are two basically different kinds of time occurring simultaneously in Music for 18 Musicians. The first is that of a regular rhythmic pulse in the pianos and mallet instruments that continues throughout the piece. The second is the rhythm of the human breath in the voices and wind instruments. The entire opening and closing sections plus part of all sections in between contain pulses by the voice and winds.
