Welcome to the forum, Christine!
I think I understand you. I am a Slav, a Ukrainian, currently with a GOA parish (simply because it's the closest to where I live, "only" 50 miles), and I, too, feel a kind of "musical void." The Greek liturgical singing is extremely complicated for me to adjust to and to join. Actually, in our parish only ONE person REALLY sings the ancient Greek liturgical tunes; a few other people TRY to "chime in" more or less successfully, and the majority of the parishioners simply do not sing. It's just too difficult. Maybe if we met between the Divine Liturgies and practiced, it would become better; but we never do that - we all live in different places, scattered over our rural or semi-rural northeastern Mississippi inland.
I am not saying that I *dislike* the Greek singing. There is, for example, a piece of Greek liturgical music performed by Divna Ljubojevic that I like immensely (http://www.youtube.com/watch?v=QR3Y5hDncn4
). I heard it so many times and I am sure I could repeat it without any help, both the tune and the words. (I have an excellent ear from music and a very good, sharp melodical memory, and also a talent for foreign languages - it is not difficult for me to memorize these Greek words!) But the tune of "Axion Estin" sung at our parish is very different and much, much more complicated (and not as beautiful, IMHO, as the one Divna sings in this video). It's just "the way it's always been," and no one seems to be willing to change anything...
Yet, I am very satisfied by our Divine Liturgies, overall. There is so much emotion in the chanting of our priest, and in these wonderful, breathtaking words of the Divine Liturgy of St. John the Golden Mouth. It compensates for the "musical void" that I experience.
I hope and pray that your situation somehow gets resolved.
