not sure where this belongs so mods feel free to move it out and about...

am i correct in assuming that a major interval has 1 more semitone than the number that denotes it (maj3 has 4 semitones)
and that a minor has the same number of semitones (m3 has 3 semitones)?

no, you're not.

a Perfect 5th has 7 semitones, minor 6th has 8, major 6th 9 etc, etc....

there is no correlation between the quality of an interval and the number of semitones.

You don't have to go about it that way. All you really need to do is remember the basic formula and you'll be able to apply it to any situation easily.

And if I'm correctly understanding what you were trying to say in your example, the distance of a Major 3rd from E would be G#, G would be a Minor 3rd from E.

The distance of a major 3rd is two whole tones (or 4 semitones). Just for reference, two semitones equal one whole tone, they're the same distance so you can say it either way. When the intervals are larger it's just easier to think 5 whole tones instead of 10 semitones.

E - F# is one whole tone and F# to G# is a whole tone, that adds up to two whole tones, a Major 3rd. Another way you could say the same thing is E - F is one semitone and F - G# is three semitones.
It still adds up to 4 semitones/2 whole tones, a Major third.

The distance of a minor 3rd is one and a half whole tones (or 3 semitones).

E - F is one semi tone and F to G is one whole tone, making one and a half whole tones, a Minor third.

Hope that didn't confuse you worse.

All you need to do is study the intervals as they are explained in the thread Cassanova linked, it's a great thread. Once you understand the names for distances between tones and you know how to relate that to the fretboard you'll be in good shape.

You'll get it.
