For example - is the sound frequency (in Hz) interval between, say, an A and a B, the same as from an F to a G, for example? Or a G to a G sharp the same as an A to an A sharp?
Are all tones and semitones the same interval? And in particular, what about from an E to an F? Or a B to a C? They are considered semitones, but are they the same intervals (in Hz) as other semitones, such as G to G sharp?

Try this link. It gives a good explanation about pitch. Concert A is 440 Hz and all other notes derived from it. http://en.wikipedia.org/wiki/Pitch_(music)

The difference in pitch between notes grows exponentially as the relative pitches increase. So the difference between an A and a Bb in one octave is different than the difference between those pitches at the next (and all subsequent) octaves.
Here's the really interesting part: A = 440, A (+one octave) = 880, then 1760, etc. A (- one octave) = 220, then 110, etc.
When you tune a piano to A 440, as the notes get farther away from A you have to 'bend' the relative pitches to keep a chord played in different octaves from clashing with eachother.
Aren't you glad you asked? ;^)
