These observations were exactly what I was hoping someone could help me with. I'll stick with a small bridge! I also raised this question because lute bridges are really rather elaborate, tapering in different directions and with the little wing things. Presumably this shows off the skill of the craftsman and and is respectful of lute-making traditions but has little effect on sound.
Talking of effect on sound. I can see and touch some of the bars in this oud. The bloke who got it for me (as a wedding present!) probably got it in Algeria and he was not a rich man at the time. It's a humble thing and the bars haven't been tapered; they are flat at the top. I wonder if this could this make a discernible difference to the actual sound?
