Johann Schop 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.
