I try to post what I have some knowledge in (late middle ages/early Renaissance music), and the truth is it's much harder to know what music was played on those ancient instruments. That's why I tend to post "demonstrations" of those, with academics explaining what they know.
That said, I'd love for more people to post in here! If you see something interesting, please do share. I'll look for more ancient instruments in future posts, too; I only do 1 per day to avoid flooding /all.
