BWV 248a is a church cantata composed by Johann Sebastian Bach. Bach wrote this work in 1733 or 1734, likely to honour a Saxon royal, possibly to welcome the new elector to Leipzig. The score and text of the piece is now lost, but part was borrowed for the Christmas Oratorio. Some sources give its title as Jauchzet, frohlocket!.
