In Leipzig, in 1723, Bach composed an initial version of the Magnificat" in E-flat Major for Christmas Vespers that year, with added Latin text related to Christmas. And then in 1733, Bach composed a version without the interpolated texts, and transposed it to D Major, for the Marian Feast of the Visitation. This choral score is of the newer D Major version, in English and Latin texts, with piano accompaniment, 66 pages."
