The string quartet was inspired by working with the Auryn Quartett and the Belcea Quartet as well as Heime Müller (Artemis Quartett), Tim Vogler (Vogler Quartett), Bernhard Schmidt (Mandelring Quartett) and Dirk Mommertz (Fauré Quartett). Master classes and workshops enriched the ensemble’s musical development.

In the same year the Vigato quartet had the opportunity to work together with Eberhard Feltz during the chamber music master classes in Frenswegen. From that on the musicians regularly continue to work with him in different courses.
