N. Simrock Berlin-London (Boosey & Hawkes)
for large Orchestra was written in 1962 as a commission for the Oldenburg Staatstheater
and was premiered there as a ballet (Pas de deux).
A seven-tone sequence (modus) of all the semitones within the tritone interval c - f-sharp dominates the whole work and gives rise through the different movements to the necessity of a multiplicity of variations on the basic material.
