If you take off a pair of headphones and lay them down somewhere, the music sounds like it's in a different pitch than when they're on your head. Why?
I have been playing around with Audacity recently trying to understand a bit more about sound in general. One question I'm having trouble wrapping my head around is: How does Tone and Frequency relate? For instance, the 2600 Hz is a high-pitched tone. Does that mean that anything that produced that same tone would be at 2600 Hz? And does it mean that for the entire range of human hearing -- all of those Hz -- that one tone corresponds to a particular frequency? I am looking for some basic explanation or even tools to play with...

Neotones: As I understand it, a note is not a pure frequency but a combination of a prominent frequency and various overtones, which are multiples of the fundamental frequency, of diminishing contribution. Is there a device, that can generate alienesque tones, where one can freely manipulate the various overtones?
My CRT monitor puts out a high-pitched whine that changes tone depending on certain conditions of which I'm not familiar with (in other words, the tone fluctuates). It's not overly loud but it's definitely noticeable - it's quite irritating. It used to do this about a year ago then stopped only to start again last week. Anybody know why it's happening and how to stop it?
