Entfernet euch, ihr heitern Sterne, BWV Anh 9
Entfernet euch, ihr heitern Sterne (Disperse yourselves, ye stars, serenely!), BWV Anh 9, is a birthday cantata by Johann Sebastian Bach. He composed it in Leipzig to celebrate the 57th birthday of King Augustus II the Strong, and it was performed for him on his birthday, 12 May 1727, on the Marktplatz of Leipzig, by students of the University of Leipzig, with Bach directing. The king was also presented with the work's libretto, written by Christian Friedrich Haupt.
The music to this secular birthday cantata by Bach is lost. It has been speculated from the surviving libretto, however, that several movements from the Mass in B minor are derived from it, and a reconstruction has been created using the Mass in lieu of this.
