MIXTUR

MIXTUR for orchestra (small ensemble), sine—wave generators and ring—modulators

SCH = PERCUSSION
H = WOODWIND
B = BRASS
P = PIZZICATO
S = STRINGS

There is only one part for each group of instruments. All parts have the same page numbers in the upper right hand corner as in the score. 2 players read from one part and have 2 stands.

SCH
3 percussionists: each 1 cymbal
1 tam-tam
each is suspended with several leather straps; for each and each 1 contact microphone fastened onto the straps or onto the surface of the instruments.
H flute (also piccolo) (F1)  
  oboe (Ob)  
  clarinet (also clarinet and bass clarinet) (Kl, Es—Kl, Bkl)  
  bassoon (also contrabassoon) (Fg, CFg)  
B trumpet (Tp)
Tp and Ps require 3 mutes: straight, cup, wawa.
  trombone (with thumb valve) (Ps)
  high horn (1. Hn)  
  low horn (2. Hn)  
P 2 violins I ( V1 I )  
  2 violins II ( V1 II )  
  2 violas (V1a)  
  violoncello (Vc)  
  contrabass (Cb)  
S 2 violins I  
  2 violins II  
  2 violas  
  violoncello  
  contrabass  

The parts include transpositions for piccolo, clarinet, clarinet, bass clarinet, contrabassoon, F horns (1. Hn high sounds a 5th lower, 2. Hn low sounds a 4th higher), contrabass.

The contact microphones of the 3 percussionists are to be connected to 3 loudspeakers (see position in the plan).

Each of the groups H B P S should sit concentrated and be separated from the others as much as possible. Every woodwind and brass player and every desk of violins and violas has a microphone; all Vc and Cb have individual microphones. The 4 microphone groups H B P S are each balanced in a mixer by a sound technician sitting with his group. The sum of each group is connected to a separate ringmodulator (if possible, special modulators, which give only the primary sum and difference frequencies).

4 further players, who also sit with their groups, each operate a beat frequency oscillator (sine-wave generator with continuously changeable frequency from 1 - or if possible a still lower frequency - to 4200 Hz). Each of these beat frequency oscillators is connected to one of the modulators. The oscillators are indicated in the score by ~.
