Johannes Peitz was born in Saarbrücken (Germany) in 1963 and received his first clarinet lessons with Adolf Heinl in Trier and Wolfgang Meyer in Karlsruhe. After leaving school, he studied the clarinet with Hans Deinzer at the Hanover University of Music, Drama und Media.

At the age of 23 he became solo-clarinetist with the radio orchestra of Norddeutscher Rundfunk in Hanover. Three years later he assumed the same post with the Bamberg Symphony Orchestra, where he played for 10 years and with which he performed worldwide and participated in numerous recordings, including the complete symphonic works of Max Reger, Karl Amadeus Hartmann, Brahms and Mendelssohn.

As a soloist, he has performed with conductors like Horst Stein and Ingo Metzmacher and partnered Sabine Meyer and the Trio di clarone in chamber works (CD). He recorded solo works and sonatas for the broadcasting corporations Hessischer Rundfunk and Norddeutscher Rundfunk. Between 1992 and 1998 he also appeared as guest performer with the Berlin Philharmonic Orchestra, the Munich Philharmonic Orchestra and the Bavarian Radio Symphony Orchestra and today many famous orchestras invite him as play with them. It was in this capacity that he played also as solo clarinet with the Concertgebouw Orchestra of Amsterdam.

Alongside his orchestral work, Peitz has always been an active chamber musician and is a founding member of the Albert Schweitzer Oktett, with which he has performed in the Chamber Music Hall of the Berlin Philharmonie and recorded two albums.
