The Krönungsmesse, composed in 1779, is one of the most popular of Wolfgang Amadeus Mozart's 17 extant settings of the Ordinary of the Mass. While it is relatively short, Bruce C. Macintyre, writing in the Cambridge Mozart Encyclopedia, classifies it as a Missa Longa, on the basis of the festal character, size of the orchestra, which includes a substantial brass section, orchestral introductions for the movements and the setting of the intonations for the Gloria and Credo.
