His own compositions include both vocal and instrumental works. The Clarinet Concerto, Op 29, is in three linked movements, paralleling the form of Mendelssohn’s Violin Concerto. Another feature common to both works is the entry of the soloist after a few introductory bars—a gesture which denies the orchestra the opportunity for its own exposition. Though no one would claim that Rietz is the equal of Mendelssohn his musical language is serious, and generously endowed with melody and harmonic intensity. The slow movement attains a level of serenity which lifts the Concerto well above the merely workmanlike. The infectious rhythms of the last movement lead ultimately to an ebullient coda with orchestra and soloist joining together in a dash to the finishing post and the prize of an ending in the major.
