Dieterich Buxtehude (1637 – 9 May 1707) was a Danish organist and composer of the Baroque period, whose works are typical of the North German organ school. As a composer who worked in various vocal and instrumental idioms, Buxtehude's style greatly influenced other composers, such as Johann Sebastian Bach and George Frideric Handel. Buxtehude is considered one of the most important composers of the 17th century. Although more than 100 vocal compositions by Buxtehude survive, very few of them were included in the important German manuscript collections of the period, and until the early twentieth century, Buxtehude was regarded primarily as a keyboard composer. His surviving church music is praised for its high musical qualities rather than its progressive elements.

The chaconne is a type of musical composition often used as a vehicle for variation on a repeated short harmonic progression, often involving a fairly short repetitive bass-line (ground bass) which offers a compositional outline for variation, decoration, figuration and melodic invention. In this it closely resembles the passacaglia. It originates and was particularly popular in the Baroque era; a large number of Chaconnes exist from the 17th- and 18th- centuries.

Psalm 113 is the 113th psalm of the Book of Psalms, beginning in English in the King James Version: "Praise ye the Lord, O ye servants of the Lord". The Book of Psalms is part of the third section of the Hebrew Bible, and a book of the Christian Old Testament. In Latin, it is known as 'Laudate pueri Dominum. In the slightly different numbering system used in the Greek Septuagint version of the bible and in the Latin Vulgate, this psalm is Psalm 112.

The psalm forms a regular part of Jewish, Catholic, Lutheran, Anglican and other Protestant liturgies. In Judaism, it is the first of the six psalms comprising the Hallel, a prayer of praise and thanksgiving recited on Rosh Chodesh (the first day of the Hebrew month) and Jewish holidays. In Catholicism, it is one of the psalms included in the vespers service. It has been set to music often, notably by Claudio Monteverdi in his Vespro della Beata Vergine of 1610.
