I need some help with this in order to tag two pieces by Radeck -- the Courante Sarabande and Engellischer Mascharada, and one by Scheidemann -- Englische Mascharada. I've never seen keyboard tablature before, so I need to know if this for one keyboard player or more. Anyone adept at reading this?

Keyboard tablature is almost always for one player (two players would be explicitly specified).
I've been meaning to create an easy introduction/tutorial to reading tablature - would anyone be interested?
