The time stamps of the different verses are on the timeline of the video.

Samuel Scheidt (1587-1654) was a German composer, organist and teacher of the early Baroque era. Scheidt was born in Halle, and after early studies there, he went to Amsterdam to study with Sweelinck, whose work had a clear influence on Scheidt's style. On his return to Halle, Scheidt became court organist, and later Kapellmeister, to the Margrave of Brandenburg. Unlike many German musicians, he remained in Germany during the Thirty Years' War, managing to survive by teaching and by taking a succession of smaller jobs until the restoration of stability allowed him to resume his post as Kapellmeister. When Samuel Scheidt lost his job because of Wallenstein, he was appointed in 1628 as musical director of three churches in Halle, including the Market Church.

Scheidt was the first internationally significant German composer for the organ, and represents the flowering of the new North German style, which occurred largely as a result of the Protestant Reformation. In South Germany and some other countries of Europe, the spiritual and artistic influence of Rome remained strong, so most music continued to be derivative of Italian models. Cut off from Rome, musicians in the newly Protestant areas readily developed styles that were much different from those of their neighbours.
