As a chamber music pianist in various ensembles (Ensemble Amphion), as a sought-after duo partner and song accompanist, he is always a sympathetic and impulsive musician.

In recent years, he has increasingly dealt with the performance practice of “old music” and playing on historical instruments (harpsichord, clavichord). As a pianist and harpsichordist, he is regularly heard at renowned festivals such as the Traunstein summer concerts or the Chiemgau music spring.

He was able to live his passion for jazz and improvised music in the jazz formations “Nimm Dry”, “Bellman Band”, “Hartmann-Karger-Schöftenhuber Trio” and in the Spanish rock ensemble “All Extasy”. As keyboardist for the band “Crush” and the band “Baby Palace” (which won the German Rock and Pop Award in 2002), he provided hot piano grooves and atmosphere at rock concerts and festivals.

In the field of solo piano, he feels especially committed to modern, jazz-inspired, classical, and contemporary music (collaboration with Ambitus – group for new music). In addition to his work as a pianist, he also performs as an organist as a soloist and in chamber music ensembles.

A multitude of “Jugend musiziert” award winners, professional musicians, as well as passionate amateur musicians produced his pedagogical work as a piano teacher at the music school Traunreut and as a private teacher.

His extensive compositional oeuvre ranges from symphonic works (solo concerts), a variety of chamber music ensembles (from duo to dectet) to jazz band compositions to music theater productions. In the meantime, his works are being presented at well-known festivals such as Chiemgau Music Spring, Traunstein Summer Concerts, Upper Bavarian Culture Days and Jazzweekend Regensburg.
