Verjaget, zerstreuet, zerrüttet, ihr Sterne (Dispel them, disperse them, you heavens), BWV 249b, is a lost cantata by Johann Sebastian Bach.
The number assigned to Verjaget, zerstreuet, zerrüttet, ihr Sterne in the BWV catalogue indicates that some twentieth-century scholars thought the work was related to the Easter Oratorio BWV 249, which was first performed in 1725 at Easter.
[2][3] The case for this linkage is based on Bach's habit of recycling music for "one-off" occasions in a process called parody.
The Easter Oratorio is an example of parody, being based on a lost work, Entfliehet, verschwindet, entweichet, ihr Sorgen, BWV 249a, premiered in February 1725.
It has been possible to reconstruct the music of BWV 249a, matching the score of the Easter Oratorio to Picander's secular text.
