Reger was a prolific composer, continuing the tradition of Bach, Mozart and the great German composers of the nineteenth century. His organ compositions, in particular, represent a very significant addition to the repertoire of the instrument. Reger also left an equally extensive body of chamber music, songs, choral works and orchestral compositions. The infrequently recorded Clarinet Quintet, Reger’s last completed work, displays all his resources of chromaticism. The String Quartet in E flat major, arguably his best known quartet, is noteworthy for its expressive and romantic slow movement.
