In the Gloria and the Credo, Mozart eschews the traditional concluding fugues. Despite being a missa brevis, the Agnus Dei is very long and there is "a prolonged setting for soloists and choir of 'Dona nobis pacem', ending piano." The Dona nobis is set as a gavotte, "like a vaudeville and has been compared with the specimen of this genre at the end of Die Entführung."
