No, two part is not natural. It takes alot of paitience, and hard work. Who ever is directing has to really listen to your men, and figure out who can sing the high tenor, who can sing the mid tenor, and then the low, and if you got two or more , that nice baritone.Our Male Chorus loves to listen to Quartet groups. So we kind of fashioned our selves that way. We dont really try to do chior bases songs, like say something by TONE', or kirk Franklin,Isereal,Mary Mary, etc, etc, if you get my drift. We stick to songs by the Cantons,Darrel Mcfaddon,Lee Williams,Mighty Clouds of Joy,the Soul Serchers,just to name a few. I have seen that it was easier for the guys to connect with a male based group then with a contemparary group. We sit and Listen first, then we get the words and practice, each ones parts. And we end up with a three part harmony. And sometimes a 4 part, cause i can sing high tenor part. Just keep trying, and like i said, stick to All Male Gospel Group songs, cause my guys wont sing a song if it's a song by a woman.Me myself i dont care, if a song touches my heart, than i want to sing it, but some men are funny about that.Keep praying, and keep trying, they'll get it, but do break all the guys up into there natural parts, then it should be alot easier.
