Here’s a podcast about Glenway Fripp’s discovery of standing waves that seem to miraculously form in certain places when a B-flat note is played, sung or, in this case – whistled: http://atlantic.org/sonic-ids/b-flat
And a snippet more about him from NPR: http://www.npr.org/templates/text/s.php?sId=7442915&m=1
Closer to home, a friend of mine was telling me a few years ago about an experience he had while jamming where a note that the band was playing seemed to just hang above his head – floating there. They all took it in turn to move into that part of the room while playing the note, and they all experienced it, seemingly dwelling above their heads – taking on a life of its own – like some sort of zero-point energy source.
My friend says he has a recording of that, too. It will be interesting if he can dig it out.
