Together
unique.

The team behind Sonat Vox is made up of several ensemble members. In addition to our shared passion for music, each singer follows his or her own professional path. This diversity gives us a wide range of skills and competencies to develop our full potential in the planning and realization of all projects. Combined with our long-standing friendship, it forms the basis for a professional working relationship, open communication and a shared vision for the future of the ensemble.
