J. S. Bach -"Meine Seele erhebt den Herren" BWV 733

Once attributed to Johann Ludwig Krebs, the "Fuge über das Magnificat" BWV 733 is now definitely acknowledge as stemming from Johann Sebastian Bach himself. It is a fugue in four parts, ending in five parts.The fifth voice gloriously reintroduces the subject as the augmented "cantus firmus" in the bass. Such a fugue shows much of a flamboyant "fantasia". According to Peter Williams, "Here, the writing is closer to the big organ fugues - compare its close with BWV 540 or 545 - and the two five part sections are as well conceived as anything in mature Bach." ( In "The Organ Music of J. S. Bach", p. 476, 2nd edition -2003- Cambridge University Press).
This masterpiece was passed down to us thanks to copies by or via (Op. cit., p. 474) Oley, Kirnberger and Krebs (two copies).
