G-Dur. Par MOZART WOLFGANG AMADEUS. The G major mass of Mozart followed a very special type of mass pattern, namely, that of the 'Missa pastoralis'. In Mozart's time it was a widespread type of mass, especially in Bohemia and Italy, in which melodies and rhythms like those familiar from pastoral Christmas music were frequently found. The themes in this type of mass are song-like and often make use of folksongs or references to well-known tunes. / Messe / Répertoire / Solistes SATB, Choeur SATB, 2 Violons, Violoncelle
