Volume I comes with a CD featuring 27 popular pieces for clarinet and piano. These pieces illustrate the entire stylistic range between Baroque and Pink Panther. They have been recorded in two versions: one is an aural document presenting the complete work; the other features only the piano accompaniment, which lets the clarinetist supply the missing part on his own.

Koch presents a new selection of pieces for clarinet and piano in "Von leicht bis virtuos." The first volume contains the piano accompaniments to Volume I of the method.
