It seems daft to me for players of Renaissance music to play with a "renaissance" sense of intonation because to modern ears it sounds "off" - which it clearly wouldn't have done to listeners in renaissance time. Also, I've noticed that young irish fiddlers don't play with the same intonation as say Michael Coleman. Of course, to contradict myself somewhat, I wouldn't expect string players from the middle-east to adjust their intonation just to please my ears!
