Dietrich [Diderik Hansen] Buxtehude was an organist and composer of the Baroque period. Not only the year, but also the country of his birth is uncertain and disputed. Since he spent his early years in Helsingborg in Skåne, at the time part of Denmark, he is by some considered a Danish composer. Others, however, claim that he was born at Oldesloe in the Duchy of Holstein, (now Germany), which at that time was a part of the Danish Monarchy. Later in his life he Germanized his name, his new name being Dietrich Buxtehude. His early youth and birthplace remain a mystery. Most scholars recognize that he studied music with his father, Johann, who had a great influence on him. J.S. Bach did meet him and study for several months in 1705 and 1706.

The Buxtehude-Werke-Verzeichnis ("Buxtehude Works Catalogue", commonly abbreviated to BuxWV) is the catalogue and the numbering system used to identify musical works by the German-Danish Baroque composer Dieterich Buxtehude (c. 1637 – 9 May 1707). It was compiled by Georg Karstädt and published in 1974 as Thematisch-Systematisches Verzeichnis der Musikalischen Werke von Dietrich Buxtehude. The second edition, published in 1985, contains minor additions and corrections. The catalogue is organized thematically, not chronologically, and contains 275 individual pieces. The Anhang ("Appendix") adds 15 spurious and falsely attributed works.

"Nun lob, mein Seel, den Herren" (Now praise, my soul, the Lord) is a Lutheran hymn written in German by the theologian and reformer Johann Gramann in 1525. It was published in 1540 and appears in 47 hymnals. A translation by Catherine Winkworth, "My Soul, now Praise thy Maker!", was published in 1863. Dieterich Buxtehude composed a chorale fantasia, BuxWV 212, in C major, and three organ preludes, BuxWV 213–215
