An insteresting case of self-borrowing. Bach took music from this work for his own Mass in B-minor (BWV 191/1 corresponds to the Gloria in excelsis Deo, BWV 191/2 to the Domine Deus, BWV 191/3 to the Cum sancto spiritu). This unusual cantata, the only one with a Latin text, may have been written to celebrate the Peace of Dresden (which ended the 2nd Silesian war) and first performed on Christmas day, 1745. This newly engraved, carefully edited vocal score is based on the Bach Gessellschaft edition. The convenient A4 size is ideal for vocalists, choruses, and rehearsal pianists.
