Johann Pachelbel
Pachelbel is best known for his organ music.  He wrote many organ pieces based on chorales while he was in Erfurt.  In Nürnberg he wrote many pieces called Magnificat fugues. These were preludes which were played before the singers sang the Magnificat. His organ music also includes toccatas, ricercares, fantasias and ciacconas.  He wrote many suites for harpsichord and chamber music and vocal music.
