The Missa brevis in G major, K. 140, K3 Anh. 235d, K6 Anh. C 1.12, was probably composed by Wolfgang Amadeus Mozart shortly after returning to Salzburg, in March 1773, from his third trip to Italy. Walter Senn, who published the Mass in 1968 for the Neue Mozart-Ausgabe, notes that this Mass is the only one Mozart composed along the lines of the Pastoral Mass type.
