Personally I would be most interested in what low frequency pitches have different measurable effects on the brain. Anyone got a study for that too?
" Fast tempo and major mode music tend to evoke a positive/happy mood and higher arousal levels, whereas slow tempo and minor mode music evoke a more negative/sad mood and lower arousal levels."
I haven't read the article yet, but this sentence strikes me as nonsense and directly contradicts findings from other studies I've heard cited in a book, where the the claim was that some "sad" music before happy music helps move through a sad mood quicker than purely happy music does. Also some of it is conditioned and "happy" music might be perceived as negative by someone who associates it with negative things and has always gravitated naturally to slower music in minor modes. If you tried to cheer me up with a happy major mode piece, I'd just get more negative, because I recoil from that kind of music. Give me something that
resonates with me, and it will be much more healing.
Interesting article, but 432 Hz is not only esoteric nonsense
The data suggests that 432 Hz tuned music can decrease heart rate more than 440 Hz tuned music. The study results suggest repeating the experiment with a larger sample pool and introducing randomized controlled trials covering more clinical parameters.

That study design seems flawed to me, because it only compares a higher frequency tuning to a lower frequency tuning, but to validate the claim that 432 hz is "the best" there would need to be even lower frequency tunings in the sample set. And in the abstract I also see no mention of the keys the music was in and what their frequency composition was.
I believe that there
are effects of certain frequencies in music, but I doubt that 432hz tunings are the most significant factor. I expect it will have something to do with lower frequencies leading to overall more relaxation and that the frequencies we should be looking at are in the frequency ranges that brainwaves are in.
I suspect that the trend in modern metal to tune guitars lower and lower has something to do with this too. Metal started on E-standard as far as I know, and now it's more than an octave lower on the extremely downtuned end. There has to be a reason why this seems to be working.
