The choral soprano part for one work by this composer begins with arpeggiated E-minor chord on the word "Kommt." This composer revamped an earlier work by removing (*) Christmas interpolations from its original text and moving the key from E-flat major to D- major; that work uses sustained notes by the orchestra to create a "halo effect" around speech. The "Gratias aginus tibi" movement from one of this composer's works is identical to the "Donna nobis pacem" movement that ends that work, whose name comes from its key.
