I've often wondered about sound waves myself. Accelerated learning techniques often incorporate baroque music as helping. I was told by a geneticist who studies these things that listening to certain classical music trains childrens brains to think mathematically.
My question if you know, your friend, or anyone here knows (Bob?) is does the source of the sound make a difference? Here's what I mean. I can have an electric piano and a string piano. Both instruments make the same sound. I have a hunch that the string piano affects me more than the electric due to different rates of vibration.
