If your contention were really to hold water, we'd have to ban the use of grandfather clocks, carillons and orchestra chimes. The reason is that the bell tones produce minor third overtones, and minor thirds are "unresolved". I dunno about you, but I'm not willing to part with my clock just yet.
Minor chords are resolved. There are no conflicting notes. Take the chord "C".
Major C E G
Minor C Eflat G
The third is changed, flattened, and everytime you hot the note, all the way up the keys, you will have to play an Eflat.
Let's compare it with C major 7th....
C E G B
There is a conflict here, as B & C don't fit together. If you don't believe me, play the B & C notes next to each other, over & over, & tell us how long it took for your wife to throw something at you......they contrast.
I'm not saying it's evil, I'm not saying rock & roll is sinful, I'm asking if we should work to be like Christ when we worship him in music.....
