Greetings,

I enjoy listening to music that is usually very common in old churches and cathedrals throughout europe. It usually contains a choir of men and/or women singing (probably in Latin). I wanted to know how is that type of music called. I came across a defintion of "Gregorian Music", but I am not sure whether that is what I am looking for.

Thanks.
