Bach's chorale cantata "Wie schön leuchtet der Morgenstern, BWV 1", is first performed on the Feast of the Annunciation, coinciding with Palm Sunday.

There are 52 chorale cantatas by Johann Sebastian Bach surviving in at least one complete version. Around 40 of these were composed during his second year as Thomaskantor in Leipzig, which started after Trinity Sunday 4 June 1724, and form the backbone of his chorale cantata cycle. The eldest known cantata by Bach, an early version of Christ lag in Todes Banden, BWV 4, presumably written in 1707, was a chorale cantata. The last chorale cantata he wrote in his second year in Leipzig was Wie schön leuchtet der Morgenstern, BWV 1, first performed on Palm Sunday, 25 March 1725. In the ten years after that he wrote at least a dozen further chorale cantatas and other cantatas that were added to his chorale cantata cycle.

Wie schön leuchtet der Morgenstern, BWV 1, is a church cantata for Annunciation by Johann Sebastian Bach. In 1725, when the cantata was composed, the feast of the Annunciation coincided with Palm Sunday. Based on Philipp Nicolai's hymn "Wie schön leuchtet der Morgenstern" (1599), it is one of Bach's chorale cantatas. Bach composed it in his second year as Thomaskantor in Leipzig, where the Marian feast was the only occasion during Lent when music of this kind was permitted. The theme of the hymn suits both the Annunciation and Palm Sunday occasions, in a spirit of longing expectation of an arrival. As usual for Bach's chorale cantata cycle, the hymn was paraphrased by a contemporary poet who retained the hymn's first and last stanzas unchanged, but transformed the themes of the inner stanzas into a sequence of alternating recitatives and arias.

The Feast of the Annunciation commemorates the visit of the archangel Gabriel to the Virgin Mary, during which he informed her that she would be the mother of Jesus Christ, the Son of God. It is celebrated on 25 March; however, if 25 March falls either in Holy Week or in Easter Week, the feast is postponed to the Monday after the Second Sunday of Easter.
