The Minor Step Pattern and Its Scale Degrees

Every scale is just a recipe of whole steps and half steps laid over an octave. Major uses whole whole half whole whole whole half. Natural minor rearranges that recipe into whole half whole whole half whole whole. Start on any note, follow that pattern, and you get a natural minor scale built on that note. The half steps land in different spots than they do in major, between degrees 2 and 3, and between 5 and 6, instead of between 3 and 4 and between 7 and 8. That shift in where the small steps fall is what gives minor its different color: some of the notes sit a half step lower than where major would put them, and that lowering is what the ear hears as darker or sadder, not some vague mood applied to the same pitches.

Compare C major (C D E F G A B C) to C natural minor (C D Eb F G Ab Bb C). Three notes moved down a half step: E to Eb, A to Ab, B to Bb. Those are scale degrees 3, 6, and 7. Everything else, degrees 1, 2, 4, and 5, stays put. This is why natural minor is not major played with a different attitude: it genuinely contains different pitches, lowered b3, b6, and b7.

This matters going forward because minor doesn't stop at natural minor. Raising that seventh degree back up turns natural minor into harmonic minor, and that raised seventh gets a new label, leading tone, because it now pulls strongly up to the tonic the way major's seventh does. Natural minor's unraised seventh is called the subtonic instead, since it sits a whole step below tonic with no pull. Seeing minor as a specific half-step rearrangement, not a filter, is what makes those later forms make sense.
