Werk BWV 191

Gloria in excelsis Deo (Glory to God in the Highest), BWV 191, is a church cantata written by the German Baroque composer Johann Sebastian Bach, and the only one of his church cantatas set to a Latin text. He composed the Christmas cantata in Leipzig probably in 1742, for a celebration by the university of Leipzig.[1][2] The composition's three movements all derive from the Gloria of Bach's 1733 Kyrie–Gloria Mass, which the composer would later use as the Gloria of his Mass in B minor.[3]
