Hello Terry,
I followed with interest the thread involving your peripecies with stringing the oud, and I learned a lot in the process. As I always do 'round here.
With regards to the difference between Turkish and Arabic ouds: I have one specimen of both and I must say I really feel the difference. After playing
the big Arabic one the Turkish feels much more easy to handle.
But the Arabic one has a richness of sound which is very appealing, whereas the Turkish one has an intricate tapestry of harmonics. Pro and cons in
every one. So, really it depends from what you're most attracted to in terms of sonority, and how much you're willing to put up with regarding the
obvious discomforts (I'm a small fella, and the Arabic oud's bowl sometimes seems to ask too much stretching for my short right arm...)
