Music by J.S.Bach
My favorite masterpiece is BVW1080 "Die Kunst der Fuge"
Link: Glen Gould talks about the Art of Fugue
English polyphony of XIV-XVII centuries (especially  J.Dunstable, Cooke, Jenkins, J. Bull, J.Dowland,  H.Purcell)
Music from Netherlands and Italy XV - XVII centuries (especially J.P. Sweelinck )
