The Swiss ensemble CHAARTS sees itself as the largest string quartet in the world. Following the example of the Lucerne Festival Orchestra, CHAARTS invites members of internationally successful string quartets and chamber ensembles, soloists, concert masters and soloists from leading European orchestras. In groups of 8 to 40 players, the musicians develop exceptional concert programs, often according to the motto ‘the big small and the small big’: works for large orchestras are arranged for chamber ensembles while music for string quartets is transferred into arrangement for large groups. As a result, these masterpieces are often completely redesigned and playable in rooms or concert series that otherwise would not be able to present this music.

CHAARTS regularly collaborates with the Hungarian conductor Gábor Takács-Nagy and has performed with great success with musicians such as Martha Argerich, Vilde Frang, Ian Bostridge, Giovanni Sollima, Mischa Maisky, Roby Lakatos, Fazil Say, Regula Mühlemann, David Orlowsky, Felix Klieser and the King’s Singers.

Oberon Trio

The Oberon Trio was founded in 2006. Shortly after the ensemble’s premier concert, the Flensburger Tageblatt already credited the Oberon Trio with “enormous interpretive abilities, which testify to the enchanting ripeness and stylistic command of this new ensemble.” Meanwhile, Oberon Trio has given performances at the Berliner Philharmonie, the Wiener Konzerthaus, the Laeiszhalle in Hamburg, the Konzerthaus Dortmund and Esterházy Palace, among others, as well as in Italy, Bulgaria, Israel, India, Egypt and the Ukraine.

Its three members are committed to offering performances of lesser-known compositions alongside with established masterpieces. Their repertoire extends from piano trios by CPE Bach and Joseph Haydn, the pioneers of the medium, to those by Jörg Widmann and Charlotte Bray, whose trios were recorded by the ensemble for the first time. Oberon Trio also collaborates regularly with chamber music partners such as Tabea Zimmermann, Ian Bostridge, Christoph Prégardien and Shirley Brill.

A special passion of the Oberon Trio is the establishment of greater intimacy between the performers and the public. Through moderated concerts and by publishing their own programme notes of performed works among other approaches, they provide listeners with an insight into their working process and the background of their interpretations.

Kronos Quartett

For over 45 years, San Francisco’s Kronos Quartet – David Harrington (violin), John Sherba (violin), Hank Dutt (viola), and Sunny Yang (cello) – has combined a spirit of fearless exploration with a commitment to continually reimagine the string quartet experience. In the process, Kronos has become one of the world’s most celebrated and influential ensembles, performing thousands of concerts, releasing more than 60 recordings, collaborating with many of the world’s most accomplished composers and performers, and commissioning over 1,000 works and arrangements for string quartet. Kronos has received over 40 awards, including the prestigious Polar Music Prize, Avery Fisher Prize, and Edison Klassiek Oeuvreprijs for career achievement.

The nonprofit Kronos Performing Arts Association manages all aspects of Kronos’ work, including the commissioning of new works, concert tours and home season performances, education programs, and the annual Kronos Festival. In 2015, Kronos launched 50 for the Future: The Kronos Learning Repertoire, an education and legacy project that is commissioning—and distributing online for free—50 new works for string quartet composed by 25 women and 25 men.



„Now after 45 years, the Kronos life journey [has become] a relentless endeavor to open up the world’s music for everyone.“

Metro Silicon Valley

„As Ben Jonson said of Shakespeare, [Kronos Quartet is] not of an age but for all time.“
