Oh and a lot of the music I listen too can actually be quite microtonic and have nothing to do with the 12 tone scale. In such cases 432 hertz is not as relevant.
Though most stuff I listen to is 12 tone scale with occasional microtonic expressions (bends, tremolo/whammy bar, wha pedal, slide strip/wheel on keyboard, fretless instruments doing sliding notes rather than 12 tone, and then eastern stuff like Sitar that is almost completely microtonic)
