"What you are trying to say is that major scales and the relative natural minor scale use the same notes, and therefore have the same chords. In other words:
A,B,C,D,E,F,G,A (A natural minor - the notes in the key of A minor)
----C,D,E,F,G,A,B,C (C major)
It would be confusing to say that they "are" the same scales."
Yes. That is what i am saying.. The only difference is the tonal center…
First learn all the major scales and their chords.. (Have you already done this?)
Then you can move to other types of scales.. Harmonic, Melodic.. All the modes… the first set of which just starts on another note of the scale..as it's center point..For example, D dorian scale, is the c major scale starting on D… (others, accordingly: phrgian, lydian, mixolydian.. etc.. ) Then there are other more exotic scales as well.. Whole tone scale, (6 whole steps) ..Diminished scale: whole step, half step, whole step, half step, continuing the same way.. Pentatonic.. (1,2,3,5,.and 6th note of the major scale)..There is the Melodic Minor scale harmony, and the 7 modes associated with it..
It is too complicated to explain here …
Here's a good book on that stuff.. "The Jazz Piano book"…by M. Levine.. It starts at a basic level, but goes quickly into more complicated stuff..
