Disclaimer: I'm not stating fact here, I'm not an audio engineer, this is just something I've noticed.
Seems like all over the world, and all through out history, there have been many different kinds of spiritual music. Some examples would be: Sacred Harp singing, Gregorian Chants, Native American song/dance, etc.
I seperate these from singing hymns (or Christian Rock for that matter) because people engaged in these activities have reported spiritual experiences.
The important thing here is "people engaged in", not "listening to".
One thing I've noticed about many of these is they seem to be loud and low frequency. They all sound kind of like the Ohm from meditation.
I know that some believe this is the "sound of the universe", but I want to raise a question here.
Is it possible that the "spiritual experiences" people are having while engaging in this low frequency chanting / humming / singing and a manifestation of the vibrations effect on the brain?
The skull is basically a fluid filled box wrapped around the brain. The chanting can't help but cause vibration and that vibration would certainly effect the brain.
An interesting test might be to strap someone in a chair, stick some high power headphones on them and run some low frequencies.
Could it be that humanity is essentially tricking itself into "spiritual experiences" that would otherwise be written off?
I know that many in the "Bible belt" wouldn't consider Native American peyote use to be a true path to God. But, if the vibrations also induce hallucinations, what's the difference?
Thoughts? Facts?
