O angenehme Melodei, BWV 210a

Bach first performed O angenehme Melodei cantata in 1729 and adapted it for two other occasions. The first version, performed on 12 January 1729, paid homage to Christian, Duke of Saxe-Weissenfels on the occasion of his visit to Leipzig.^[2][3] The dates of the later performances are not known, but the dedications were to Joachim Friedrich Count Flemming, the governor of Leipzig (words for that occasion given below), and, thirdly, to the Gönner von Wissenschaft und Kunst (Patron of Science and Art), this version is also called Sponsorenkantate, the sponsors' cantata).^[4][5]

Only the soprano part and a separate printed textbook of the earliest version survived into the twentieth century. The soprano part was lost in World War II. Bach used the five arias, the first recitative and the beginning of the last recitative later in his wedding cantata O holder Tag, erwünschte Zeit, therefore the music can be reconstructed.^[6] Alexander Ferdinand Grychtolik edited a reconstruction, published by Edition Güntersberg.^[7] He chose the third text version as the most general one.^[8]

The cantata in ten movements is probably scored as the surviving O holder Tag, erwünschte Zeit,^[4] for soprano, flauto traverso, oboe d'amore, two violins, viola, and basso continuo with violone and harpsichord.^[4][6]
