In 1945, he was re-employed at the Berlin Musikhochschule and additionally became director of the Potsdam Municipal Choir.[1][5] He gave lessons in music theory, composition and choral conducting. In Potsdam, he founded the "Collegium musicum" in 1945. In 1965, he was appointed deputy director of the Hochschule für Musik, a post he held until his retirement in 1969.[1][6] In 1963, he was appointed a member of the Academy of Arts, Berlin, where he became director of the music department in 1968. His students included Magdalene Schauss-Flake.[7]
Chemin-Petit was considered one of the most important choral conductors of his time and made a special contribution to the Berlin Philharmonic Choir, which he conducted from 1943 to 1981.[8][9] Besides standard works from Baroque, classic and Romantic music, the then contemporary music formed an important cornerstone of his repertoire. Thus, he conducted numerous premieres and first performances of the works of composers such as Paul Hindemith, Johann Nepomuk David, Boris Blacher, Rudolf Wagner-Régeny, Günter Bialas and Harald Genzmer, as well as his own compositions.
Chemin-Petit's main works are in the field of choral-symphonic vocal music. His cantatas and psalms settings are particularly noteworthy. He also wrote orchestral works, operas, chamber music and numerous smaller pieces for choir a cappella. He was a conservative composer whose works are consistently tonal. What is striking about many of his compositions is a great preference for contrapuntal forms of composition, such as canon, fugue and passacaglia, which he was able to shape with sovereign mastery, even in their most complicated forms. Chemin-Petit's style unites various influences from Heinrich Schütz and Johann Sebastian Bach to Anton Bruckner, Max Reger and Paul Hindemith and can be characterised overall as Neoclassicism rooted in the tradition of German late Romanticism, in which archaising and modern elements come together.
