Gloria in excelsis Deo, 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. 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.
