Dietrich [Diderik Hansen] Buxtehude (1637/39 – 1707) was a Danish-German organist and composer. For the last forty years of his life he worked in Lübeck, where he was organist at the large Mariairche. Buxtehude was the greatest composer of the northern European Baroque in the period between Heinrich Schütz and J.S. Bach. His fame as an organist was very considerable. Johann Sebastian Bach walked all the way from Arnstadt to Lübeck to study with Buxtehude, and was crucially influenced by his meeting with the older composer, as was Händel.
The Chorale Prelude Wir danken dir, Herr Jesu Christ is transcribed from manuscript Mus.ms. 22541 III, owned by the Staatsbibliothek Berlin. Again, I made two versions. In one the left hand is notated with the alto-clef. In the other the left hand is notated using the ‘modern’ treble and bass key.
