BWV_Anh._18
Froher Tag, verlangte Stunden (Happy day, long hoped-for hours), BWV Anh. 18,[lower-alpha 1] is a cantata by J.S. Bach. He composed the work for the inauguration of a renovation of the Thomasschule, Leipzig. It was first performed on 5 June 1732. The music is lost but the words have survived. They are by Johann Heinrich Winckler, a teacher at the school.[1][2]
In 1731 work began on the reconstruction of the school building, giving it two more storeys. The Bach family, along with other residents, had to move out for a year. On the Bachs' return they benefited from an enlarged apartment. The building is no longer extant.
