Mischa Greull

Mischa Greull, born in Basel, was principal horn in the Tonhalle Orchestra Zurich for 30 years and has been a professor at the Zurich University of the Arts for 20 years.

His studies in music took him from Bern via Winterthur to Germany, where he also found his first position in an orchestra.
Known for his expressive and soft sound, Mischa Greull prefers to play works that were originally composed for the valveless natural horn and therefore represent a particular tonal challenge for the performer. Important chamber music and solo works for horn were also written during the transition period (end of the 19th century) from the natural horn to the valved horn. These include the Horn Trio by Johannes Brahms, the Duo Adagio and Allegro by Robert Schumann and the Larghetto by Emmanuel Chabrier for horn and orchestra.

Since his studies at the Bern Conservatory and the Schola Cantorum Basiliensis, Mischa Greull has been working on the playing techniques of the natural and valve horn. Chamber music by Haydn and Schubert played with original instruments, but also orchestral works, in particular the cycle with all of Beethoven’s symphonies in 2014 with the Tonhalle Orchestra Zurich under the direction of David Zinman, are important examples.

Numerous chamber concerts on international stages with a wide variety of instrumentations from Brahms Trio to Mozart’s Gran Partita characterize his musical career. He works closely with his colleagues in the wind quintet Swiss 5 and the pianist Seung-Yeun Huh. A CD with works by Brahms, Schumann, Beethoven and Widmann was released with the latter in 2017.

Mischa Greull has been principal horn of the Gstaad Festival Orchestra under the direction of Jaap van Zweden since 2020.
In addition to his professorship at Zurich University of the Arts, he also teaches chamber music and music physiology. Since 2022 he has been head of the major program of the brass department of the ZHdK. He also gives masterclasses in Europe, the USA, Canada and Asia
