The Magnificat in its final form has become one of Bach’s most famous sacred works. It opens and ends with two powerful choral movements between which the vocal and instrumental soloists interact according to constantly varied formulas of a confusing abundance of invention. The Cantor shows its sense of the image, to align the musical expression with the symbols of the libretto. Among the most original ideas, we highlight the choir singing on the words «omnes generationes» to evoke the multitude of humans across generations, the duet subtly balanced for alto and tenor with flutes in «Et misericordia», the impressive choral fugue of «Fecit potentiam» that expresses the power of the Lord, the limpid trio for 3 sopranos in «Suscepit Israel» and the first choir’s return to the topic for the final «Gloria Patri». Beyond these brilliant ideas, this festive work confirms Bach’s never- denied affection for the character of the Mother of Christ.
