You got that right, Kevin: When we work out harmonies in my quartet, we just find out what works within our own range. We have a bass, two baritones and a second tenor, so our harmonies are of necessity, farily tight, except when someone sings in falsetto. There are some songs where, within the song Frankie and I (we're both baritones) switch back and forth between a baritone and a second tenor harmony, while our second tenor has to move up to first tenor. The switches are necessitated as different singers sing verses as the "lead,: causing everyone buy the bass to shift around. None of us read music all that comfortably, or have any understanding of chord theory. We do what we can, that sounds best to our ears.
