('How beautifully the morning star shines'), 1, is a church cantata for Annunciation by Johann Sebastian Bach. In 1725, when the cantata was composed, the feast of the Annunciation (25 March) coincided with Palm Sunday. Based on Philipp Nicolai's hymn "" (1599), it is one of Bach's chorale cantatas. Bach composed it in his second year as Thomaskantor (cantor at St. Thomas) 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. is the last chorale cantata of Bach's second cantata cycle, possibly because the librettist who provided the paraphrases for the middle movements of these cantatas was no longer available. Bach scored the work for three vocal soloists, a four-part choir and a Baroque instrumental ensemble of two horns, two oboes da caccia, two solo violins, strings and continuo. The chorale melody of Nicolai's hymn appears in the opening and closing choral movements of the cantata. All instruments play in the opening festive chorale fantasia, in which the soprano sings the hymn tune, and the two solo concertante violins represent the morning star. An oboe da caccia accompanies the vocal soloist in the first aria. The strings, including the solo violins, return in the second aria. An independent horn part crowns the closing chorale. The original performance parts of the cantata, partly written by the composer, are conserved in Leipzig. Commentators writing about the cantata, such as Carl von Winterfeld in the 19th century and W. Gillies Whittaker in the 20th century, were particularly impressed by its opening chorus. The Bach-Gesellschaft published the cantata in 1851 as first work in the first volume of their complete edition of Bach's works. From then on known as Bach's Cantata No. 1, it retained that number in the , published in 1950, and its recording appeared, in 1971, as first work of the first album of Teldec's complete Bach cantata recordings by Harnoncourt and Leonhardt.
