Semi tones and whole tones

If when you move down or up a semim tone on the guitar and it is one fret and a whole tone is 2 frets is this because when your moving say from g to a it is 2 frets because of the sharp if thats the case when you move a whole tone up from say e to f is that only one fret?

to e to f there is no sharp/flat. Meaning there is only 1 fret difference from an E to an F, of B to a C for that matter. All the other intervals between notes is 2 frets. So by the sounds of things you have the idea right.

a semitone on guitar is always 1 fret, and a whole tone is always 2. always. Doesn't matter what note you're on. But check out my Grade 1 lesson for more info on that and you'll understand it completely :)

ok cool thanks guys
so jazz does that mean that a whole tone from e would take you 2 frets up to f#?

@ MuseFan

YES

In the same way B to C would = 1/2 while B-C# would = whole

always(as JM said) true.

Cool maked a lot more sense now lol thanks a lot guys
