If the third is semitone lower, or half step lower it makes it a scale\chord minor?
does this make any sense?
im not sure what you mean exactly, but c-d-e-f-g-a-b is the C Major scale. if there is anyone out there more knowledgeable on their theory please jump in, but thats a maj scale dude.
and the second d-e-f-g-a-b-c is the D Dorian scale, which is KIND of minor.
