(and no - its not a "gateway to hell" - it's a gateway to music
appreciation. The subtleties of tones, harmonics, a little bit
of meditation. The placebo effect, though could be dangerous -
get kids to believe that its real and they act out on it. Goes
in the same category as the infamous "brown note" - the supposed
frequency which makes your bowels uncontrollably "move". No such
thing, although there's plenty of "crappy" music out there. :-)
