2. Some sort of strange three-necked stringed instrument is in the camp (one assumes it belongs to Leiliana, if recruited) and for sale in the Denerim Market. The 'tavern music' that plays in several of the game's taverns seems to evoke woodwinds and drums.
You don't start seeing matched, tuned consorts of woodwinds (e.g., recorders) til the Renaissance in our world. We do have remains of bone and wooden end-blown fipple flutes (like a pennywhistle, not like a concert flute).
The new music for 'Leiliana's Song' reminds me of a plucked or strummed instrument (maybe that weird three-necked thing). It sounds sort of classical guitary to me, although that particular instrument is also rather late.
1. I think the tavern music is the only soundtrack which is meant to represent music as-played by Fereldens. One suspects the Chant of Light, since it was originally sung by Andraste, has a tune.
Can I tell you I was soooo excited to hear the dwarves at Tapster's reciting what I thought was Old Englishy or Nordic poetry, only to realize it was the usual pub music slowed down to a drunken slur? <_<
I can rattle off the characteristics of medieval music in a nutshell, if you want that. But there's nothing connecting it to lore.
3. We have slim evidence for early medieval dance (pre-1300). Dance is not my 'thing' (music is), but what I do know suggests lines or circles of couples using fairly simple steps in combinations that range from simple to complicated. Steps and hops front, back, and left or right, either singly or in pairs. This might be done to music or to someone singing, and may have even been spontaneously choreographed by the dance leader. (There are some descriptions in Bocacchio's "The Decameron" that illustrate this.)
I envision the Remigold as an estampie - we don't know too much about those (although we have some tunes), but the name suggests stamping. So, something a touch on the energetic side.
Sheerest invention - A simple Remigold, a dance for lines of partners. Gentlemen on the left, ladies on the right, or as you will.
