Hat Tip to Lucas Grassi Freire

"Jan Pieterszoon Sweelinck (15621621) was a Dutch composer, organist, and pedagogue whose work straddled the end of the Renaissance and beginning of the Baroque eras. He was among the first major keyboard composers of Europe, and his work as a teacher helped establish the north German organ tradition." — amadeus9man
