the Magnificat, published by Picander in his 1728–29 cantata cycle for performance on 2 July 1728, may have been set by Bach. Similarly, a Meine Seele erhebet den Herrn cantata by an unknown librettist for Visitation 1725. Further, Bach copied Latin Magnificats by other composers: in the early 1740s Bach copied Antonio Caldara's Magnificat in C major, arranging its Suscepit Israel movement (BWV 1082). is a Magnificat in C major for double SATB choir and orchestra, copied by Bach around 1742. The manuscript score indicates no composer, but in 2012 it was discovered that it is Bach's arrangement (by adding parts for timpani and for a third trumpet) of a late 17th-century composition by Pietro Torri. An earlier attribution of the work had been to Antonio Lotti. Structure and movements Bach's Magnificat consists of eleven movements for the text of Luke 1:46–55, concluded by a twelfth doxology movement. Each verse of the canticle is assigned to one movement, except verse 48 (the third verse of the Magnificat) which begins with a soprano solo in the third movement and is concluded by the chorus in the fourth movement. The traditional division of the Magnificat, as used by composers since the late Middle Ages, was in 12 verses: it differs from Bach's 12 movements in that Luke's verse 48 is one verse in the traditional division, while the doxology is divided into two verses. There is however no numbering of movements in Bach's autographs, nor is there a caesura between the third and the fourth movement: the 25th measure of the Quia respexit (where the soprano soloist sings their last note) is the first measure of the Omnes generationes movement. The four Christmas interpolations are placed after the second, the fifth, the seventh and the ninth movement on the Magnificat text. These four laudes movements are usually indicated by the letters A to D, with these text sources: A: Hymn by Martin Luther B: Verse attributed to Sethus Calvisius C: D: Fragment of a Christmas hymn Performance time of the Magnificat lies typically between 25 and 30 minutes, with an additional five minutes for the Christmas interpolations. The duration of the version without Christmas hymns is comparable with that of an average Bach cantata. However, there are many differences: the Magnificat contains about twice as many movements as an average cantata, keeping it short by avoiding da capos in the arias, and
