It's a 'intellecktal ploblem' o the brain assuming since there is a unified theory of Chords, music as played is the same thang.

It ain't.

On the same instrument Chords do behave more or less like the theories, Ie playing a C# over C Major sounds like a cat in a coffee can, BUT if the same combination is played on unrelated instruments eg., voice and string, then the effect can be very beautiful.

I suspect, but since I am not a an expert, that we have the tendency to 'think' way too much about these things.

BTW An interesting comparrison is mixing colors in Art, in fact theory
is a bad case of the urge to explain stopping us from hearing, or playing ... the real thang.
