im talking more just about half step formulas. You can do any chord or scale from any key if you know the half step formulas. Intervals are a pain in da a$$ half steps, are much eaiser to rember. Like a
C major chord
is
4, 3
so that means from the c key. I go 4 half steps(C#, D, D#, then E) so E is the next key I have to hold down in the chord. Then I go another 3 halfsteps. (F, F#,then G). This is the last key (g) you hold down. So a C major chord is when you press CEG at the same time.
It works on any key. Just got 4, then 3 from the key you want to find.
A major scales halfstep formula = 2-2-1-2-2-2-1
SO for a C major scale I would go
2 from C, = D
then another 2 halfsteps =E
Then 1 = F
then 2=G
then 2= A
then 2 = B
then 1 =C
so
2-2-1-2-2-2-1
works on any key or fret.
This page has every scale and chords halfstep formula.

Now you can take all that interval sh** and throw it out the window. You now know how to do any scale and any chord from any key on a keyboard.
Remeber a half step is just the next key in succesoin.
Aight a halfstep is the first white key to the black key right next to it. That is a half step. A whole step would be the first white key to the second white key.
4 half steps would be to the first white key to the 3 white key. Because you are counting the black keys also. Its like jumpin accorss stones.
Also for the musically imparred. The keys notes are like this
C, C# (the 1 black key) then D D# E F F# (3rd black key), then G, G#, A, A#, B then C. Those notes can equal flats going from the last white key back down the line.
