Thanks so much for the responses so far - they have been spectacularly helpful! I'll be looking these all up and trying them. I apologize for not being able to respond to everyone's post in a more timely manner, but I have limited access to the internet at home and can only use the internet at work during the lunch hour.

katlaughing: I am eager to hear what Aine says. If you feel that it is more proper that I also e-mail, i can certainly do that as well.

To Jack and others who might be wondering: This "OP" is obviously very new to all of this (posting to a forum, music, etc.). I'm afraid I don't know much about what is the proper way to term certain types of music, and I certainly didn't mean to offend! :( Most of my musical knowledge (limited thought it is) concerns European medieval and Baroque music and American Broadway/Songbook standards (and that might not even be the right descriptions for them! :)).

When I hear what is broadly termed "Celtic" music on American radio, it usually refers music from the Scottish, Irish, Welsh, Canadian/Nova Scotian, and Briton countries/regions (and American copycats of the style :)). Since I have no preference to music from any particular region, I used what I considered a generic term, hoping that people would forgive my naivete.

Any suggestions people have is fine and I'll try singing anything once! :) My only concern with Arabic region music is singing it wrong, especially with the quarter-tones and the pronunciation. Of course, I might run into the same thing with Irish/Scottish/Welsh/Briton music, as well, I suppose. :( Otherwise, I like Arabic region music quite a bit. I apologize if I gave anyone the wrong impression. Also, the lady who asked me to sing for her specifically wanted something "different, like Irish music or something." So, here I am posting this odd question! ;)

I will try checking again when I get home from work. Thanks again for all of the suggestions so far!
