It depends on where you live. If you live in Toronto, Detroit or Toledo you can probably find one. Also maybe Worchester, Mass or there abouts and possibly Huntington or Charleston, Wv. I'm trying to think of places where there are large enough populations of Arabic speaking people to support musicians.When Arabic speaking people put on a party (hafli) it's the best party you've ever seen but they often have to bring musicians half way across the country because there are so few here.
Look in your local phone book to see if you have a Serian or Antiochian Orthodox Church or perhaps a Mosque then call them and ask questions. If they know of anyone they'll surely give you a lead.
