In the classical music world, violinist Christian Tetzlaff is known as an exceptional musician and is highly praised for his expressive and sensitive interpretations. His individual approach to the score, in which he always seeks the emotional and structural depth of a composition, is often described in concerts as a truly existential experience. Since his spectacular debut with Schoenberg’s Violin Concerto in Berlin, Munich and Cleveland in 1988, this violinist has performed with leading orchestras of the highest calibre and has collaborated with multiple renowned conductors. His extensive repertoire ranges from Bach’s solo sonatas and partitas to lesser-known concertos by Giovanni Battista Viotti and Joseph Joachim to contemporary works by György Ligeti, Jörg Widmann and Thomas Ades. In February 2026, the violinist is giving the world premiere of Ondrej Adamek’s Violin Concerto No. 2 in Paris, followed by national premieres in Switzerland and the Czech Republic.

Chamber music is an integral part of Christian Tetzlaff’s career. In 1994, he founded the Tetzlaff Quartet together with his sister, cellist Tanja Tetzlaff, and which was awarded the Diapason d’or l’année. This violinist has also received numerous awards for his many recordings as soloist, including the Diapason d’or, the German Record Critics’ Award and the Midem Classical Award. In 2023, he also took over as artistic director of the Spannungen Festival in Heimbach. This extraordinary musician has enjoyed a close friendship with The Deutsche Kammer­philharmonie Bremen for many years.

Ludwig Müller, born in Leoben (Steiermark) studied with Valery Gradow and Klaus Eichholz, then with Günther Pichler and Ernst Kovacic at Graz and Vienna Colleges of Music respectively. The decision to award him a first class performance degree (violin) was unanimous.

As well as with the Deutsche Kammer­philharmonie Bremen, he is Guest Concert Master with the BBC Symphony Orchestra, the OBC Barcelona, the Orquestra de Castilla y Leon and the Orquestra Gulbenkian. He has been Concert Master with the Vienna Chamber Orchestra since 1986 and with the Orquestra de Cadaques since 1992.

In this role he has performed with conductors such as Ivor Bolton, Richard Eggar, Reinhard Goebel, Thomas Hengelbrock, Heinz Holliger, Sir Neville Marriner, Krysztof Penderecki, Vasily Petrenko, Jukka-Pekka Saraste and Heinrich Schiff as well as with Yehudi Menuhin and Sándor Végh.

As soloist and Artistic Director, he has appeared in many renowned concert halls including those in Vienna (Konzerthaus and Musikverein), Salzburg (Mozarteum), Berlin (Philharmonie and Schauspielhaus), Paris (Théâtre des Champs-Elysées), New York (Carnegie Hall), Tokyo (Suntory Hall) and Osaka (Symphony Hall). He has also performed numerous works for radio broadcasts and CD recordings.

Between 1988 and 1998 Ludwig Müller was a member of the Arcus Ensemble Vienna which gave concerts across Europe, in Israel, Japan and the USA, and which also included his own series of subscription concerts at the Vienna Konzerthaus.

To mark the occasion of the Arnold Schönberg Centre’s opening in Vienna, Ludwig Müller founded the Aron Quartet Vienna in 1998 and which went on to become the centre’s ›Quartet in Residence‹. For the next ten years it gave its own series of concerts. In addition, the quartet appears regularly in both the Vienna Konzerthaus and the Musikverein and also gives guest appearances in many international chamber music cycles and festivals. The quartet’s recordings of Schönberg’s complete work for string quartet have been named by the music media as a seminal. The Aron Quartet has hosted its own chamber music festival in Schloss Laudon in Vienna since 2008.

Ludwig Müller is a founder member of the Korngold Ensemble Vienna.
