Hello mudcats...I am a trombone player and singer,
and have done some studying about 'perfect' intonation,
ie a C sung in a G chord will not be the exact same C, intonation
wise, as a C sung in a F chord for instance.....(it may be just
a few hertz sharper or flatter.....and that good singers tend to
hear this intuitively and maximize their harmonies for these chordal
changes...when these harmonies are maximized, the overtones created are vastly increased, and the music really opens up.....so,
to me harmonizing 'perfectly' is just another stairway to heaven.....
