I think this is a great video to look at to study continuo. Because the lute often is doubling the leading tones and other notes, you can see and develop a hearing sense for this sound, then you can decide if you like it. I want to make it clear that this is not a criticism, it just is unusual and I'm sure an artistic choice, like doubling the parts in Dowland's Lachrimae. Then you can decide when playing figures if these are figures to play, or figures not to play--not double. Warning figures, or figures just "fyi". Also there are some figures in the bass that are not in the viol part, you can listen and see if the missing harmonies are filled in by either the lute or the viol, it is a good challenge. You can also compare it to the harpsichord solo version if making a solo lute arrangement.
The youtube synch problems have been fixed, I believe, I think the problem is on the other end. If you use the H264 codec you should not have synch problems. dt To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
