The following instruments are part of the main composition of the SONEMUS Ensemble:
- Flute (piccolo, alto flute, bass flute, traverso)
- Clarinet (in B-flat, in A, in E-flat, bass clarinet)
- Piano (keyboards)
By taking on musicians – associates, the SONEMUS Ensemble can be enlarged as needed. Thanks to a network of regular associates, the SONEMUS Ensemble, even when enlarged, does not seem like an ad hoc ensemble, but instead functions as an experienced and compact musical body.
