Glaring omissions for the Czech's, Antonín Dvořák and for the far north, Sibelius.

I have no problem with Dowland being on the list. I think he was brilliant. I might have omitted Britten or Purcell and included Elgar or Holst.

I would have omitted CPE Bach and included Heinrich Schutz maybe.

Never heard of Hildegard von Bingen, Léonin, or Machaut. Never cared much about Gluck.

Tastes vary from place to place and from person to person. I have long ago realized the futility of compiling such lists. It is still human nature to do so, and fun. It's an attempt to confirm our place in the scheme of things.
