Mass no. 9 for Soloists, Chorus & Orchestra in C major, K. 196b/220 "Missa brevis", "Spatzenmesse"

The Missa brevis No. 9 in B♭ major by Wolfgang Amadeus Mozart, K. 275/272b, was probably written before September 1777 for Salzburg. The mass is scored for SATB soloists, SATB choir, violin I, violin II, 3 trombones, string bass, and organ.

The setting is divided into six movements.

Kyrie Allegro, B♭ major, 44
Gloria Allegro, B♭ major, 24
Credo Allegro, B♭ major, 44
"Et incarnatus est" Adagio
"Et resurrexit" Allegro
Sanctus Andante, B♭ major, 34
Benedictus Andante, E♭ major, 34
"Osanna in excelsis" Allegro, B♭ major
Agnus Dei Andante, G minor, 44
"Dona nobis pacem" Allegro, B♭ major, 22
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 aus dem Serail."
