Johann Schop (ca. 1590 – 1667) was a German violinist and composer, much admired as a musician and a technician, who was a virtuoso and whose compositions for the violin set impressive technical demands for that area at that time. In 1756 Leopold Mozart commented on the difficulty of a trill in a work by Schop, probably composed before 1646. He worked in Hamburg. He published books of violin music in 4 to 6 parts; some of his music was performed at the Peace of Westphalia celebrations. His melody Werde munter, mein Gemüte of 1641 was used by Johann Sebastian Bach for the chorale movements (6 and 10) of his cantata Herz und Mund und Tat und Leben, BWV 147. <a href="https://www.last.fm/music/Johann+Schop">Read more on Last.fm</a>.
