What makes a "beat" different from a "difference tone"? with respect the only
difference I see between the two is the frequency range in which they occur.
Thanks Chris

I'm not sure what you mean by "the sine in the fundamental". Of course, if
you mix sines of 600Hz and 601Hz, you CAN get some beats; but remember that
this is a rather small interval. Generally, I've always seen the term
"beats" used in situations where the intervals were smaller than about a
quarter-tone or whatever. A minor second can have perceivable difference
tones as well, but i wouldn't think of calling them "beats".
