Glory to Jesus Christ!
AMM,
I suggest you come visit the Melkite parish in VA. It is one of the reasons I love the east and it's chanting. When I went to my first Roman Mass, I asked my friend, do you guys even sing here? Most of my background comes from black protestant churches, and so (not sure if you know anything about many, I'd say most, black protestant churches, is that they LOVE to sing their hymns, song leaders and the whole congregation) and so I was kind of sad that I was going to be missing that when I became Catholic. But then I found out about the Christian East and Eastern Catholics and because of my older heritage, I was greatly attracted to the Melkite Church and was enthralled at the sight and sound of everyone singing and singing with such love and passion (or at least that is how I experience it).
I am NOT a good singer, not even remotely close to being decent. But I do my best to sing/chant along with my fellow parishoners and for me, that helps me in the participation of the Divine Liturgy and in being present to our Lord God Jesus Christ!
Like you, I'm guessing this is probably because of my past experiences. None the less, come visit us in VA sometime. I think we sound great ;-)
Kyrie eleison,
Manuel
