Why does D major scale have 2 sharps? How come the notes don't follow always to the major note like the C major scale does?
I expected
D to E whole step
E to F half step
F to G whole step
G to A Whole step
A to B whole step
B to C half step
C to D whole step
And therefore the shape of the scale is different then the C major scale?
I do understand that with the 2 sharps F# and C# you preserve the shape of the C major scale, but Im not getting the point of preserving the shape over preserving the major step.
Also does this shape apply to all major note shapes? any exceptions?
Thanks in advance.
