Gwendolyn Masin

Violin, Founder and Artistic Director

Gwendolyn Masin is a concert violinist, educator, artistic director, author, and PhD researcher. She performs internationally to praise from press and audiences, creating with musicians, artists and orchestras from all over the world. Described as “a natural performer with an authority most violinists would envy” (The Irish Times), the violinist’s virtuosity is not coincidental – Gwendolyn Masin is the descendant of a long line of professional musicians from Central and Eastern Europe. Aged five, she gave her debut performance in the Franz Liszt Academy in Budapest. Ever since, her love of the stage is tangible at every appearance: “Gwendolyn IS Music”, The Independent observed. Chamber music was part of her earliest musical experiences, one she still seeks out to enjoy wherever she can. Gwendolyn has long specialised in creating alternative means that bring more music, to more people. She founded the GAIA Music Festival in 2006 in Stuttgart and in 2009, relocated the festival to Thun. Born out of the wish to play music in deep connectedness with others, Gwendolyn, and the more than 180 musicians who have performed at the festival since its inception, find in GAIA a retreat from the hectic pace of touring life and unity with one another and GAIA’s cherished audience.

CHAARTS Chamber Artists


Das Schweizer Ensemble CHAARTS versteht sich als grösstes Streichquartett der Welt. Nach Vorbild des Lucerne Festival Orchestra lädt CHAARTS Mitglieder international erfolgreicher Streichquartette und Kammerensembles, Solisten, Konzertmeister und Solobläser aus führenden europäischen Orchestern ein.

In Besetzungen von 8 bis 40 Spielern erarbeiten die Musiker aussergewöhnliche Konzertprogramme, nicht selten nach der Devise ‹das Grosse klein und das Kleine gross›, also Adaptionen von Werken für grosses Orchester in kleinen oder etwa Streichquartette in grossen Besetzungen. Dadurch werden diese Meisterwerke nicht selten völlig neu erschlossen und in Räumen oder Konzertreihen spielbar, die ansonsten diese Musik nicht präsentieren könnten.

CHAARTS ist mit grossem Erfolg mit Musikern wie Martha Argerich, Vilde Vrang, Ian Bostridge, Giovanni Sollima, Mischa Maisky, Roby Lakatos, Fazil Say, Regula Mühlemann und den King’s Singers aufgetreten. Für die Spielzeit 2021/22 sind Projekte mit Vesselina Kasarova, Felix Klieser, Maurice Steger, Regula Mühlemann, Emmanuel Tjeknavorian, dem Janoska Ensemble und David Orlowsky geplant.
