"", which is based on the Gospel. Published in Nicolai's (Mirror of Joy of the Life Everlasting) in 1599, its text was introduced: "" (Another [call] of the voice at midnight and of the wise maidens who meet their celestial Bridegroom / Matthew 25 / D. Philippus Nicolai). The text of the three stanzas appears unchanged and with the melody in the outer movements and the central movements (1, 4 and 7), while an unknown author supplied poetry for the other movements, twice a sequence of recitative and duet. He refers to the love poetry of the Song of Songs, showing Jesus as the bridegroom of the Soul. According to the Bach scholar Christoph Wolff, the text was already available when Bach composed his cycle of chorale cantatas. Bach performed the cantata only once, in Leipzig's main church Nikolaikirche on 25 November 1731. According to Wolff, Bach performed it only this one time, although the 27th Sunday after Trinity occurred one more time during his tenure in Leipzig, in 1742. Bach used the central movement as the basis for the first of his Schübler Chorales, BWV 645. As the text and its eschatological themes are also associated with Advent, the cantata is commonly performed during that season. Music Structure and scoring Bach structured the cantata in seven movements. The text and tune of the hymn are kept in the outer choral movements and the central movement, set as two chorale fantasias and a four-part closing chorale, which frame two sequences of recitative and aria. Bach scored the work for three vocal soloists (soprano (S), tenor (T), bass (B)), a four-part choir, (SATB) and a Baroque instrumental ensemble of horn (Co), two oboes (Ob), taille (Ot), violino piccolo (Vp), two violins (Vl), viola (Va), and basso continuo including bassoon. The heading of the original parts reads: "Dominica 27. post Trinit. / Wachet auf, rufft uns die Stime / â / 4. Voc. / 1. Violino picolo. / 2. Hautbois. / Taille. / Basson. / 2 Violini. / Viola. / e / Continuo. / di Signore / J.S.Bach." The duration is given as 31 minutes. In the following table of the movements, the scoring follows the Neue Bach-Ausgabe. The keys and time signatures are taken from the book on all cantatas by the Bach scholar Alfred Dürr, using the symbol for common time (4/4). The continuo, playing throughout, is not shown. Movements
