A little info about our quartet.

Sonoro Quartet was founded in 2019 by four promising and talented musicians: violinists Mona Verhas and Jeroen De Beer, violist Kaat Schraepen and cellist Paul Heyman. Despite the fact that they are a relatively young ensemble, they are already known for their virtuosity and energetic playing, balanced by their yet mature musicality.

Sonoro Quartet is currently studying at the Nederlandse Strijkkwartet Academie in Amsterdam (NSKA) where they take lessons with renowned professors such as the members of Danel Quartet, Eberhard Feltz, Hagen Quartet etc. The quartet is also taking lessons at Orpheusinstitute in Ghent and takes lessons on a regular base with renowned professors such as Heime Müller (Artemis Quartet) and Marc Danel (Danel Quartet). This young quartet played already in numerous halls such as De Bijloke, Amuz, Desingel and played on the Beethoven Festival 2020 in Bonn the première of the first string quartet by Eric Domenech which was recorded for the SWR Television. Also, in the next season they will perform on national and international stages.

After playing a program completely dedicated to Schubert, the four musicians will play this season masterpieces from Haydn, Brahms, Schumann and Shostakovich. Besides these famous works, they will also play known and less known modern music on stage. In that way, the quartet presents itself as a unique ensemble that constantly pushes their boundaries and keeps expanding their range of colors. The fact that they keep searching for new sounds inspired the group by finding their quartet name.

The Sonoro Quartet is financially supported by vzw SWUK Vl.
