If you want peace of mind, just pitch shift all your stuff to 8 hz below and enjoy it in slightly lower frequency.
To take this all seriously, you'd have to make the tempo a submultiple of 432, and all intervals between notes "pure", lets say, in A minor or major scale (which our current scale isn't).
And finally, nothing in your listening environment should create delay, reverb which in turn would create phasing, comb-filtering and beats or whatever that resonate mathematically off the pure (sub)multiple frequencies.
What we perceive as "music" is the diferences we perceive along a time arrow pertaining to a reference which can be set anywhere. All music toned down or slowed down is perceived as more mellow and warm than it's high pitch counterpart. The same happens if you change from 432 to slightly lower. Just like moving your hands from a 20 degrees to a 22 degrees water... or 24 to 26...
Not saying 432 Hz based scale has or hasn't any special resonance, but it's not as far as music is related, it only would be as far as it's audio wave effects. All music is a mesh of sine waves and all frequencies (and sizes)seem to pervade the Universe... The same way the planets affect you, you affect the planets.
