A natural minor scale has the same notes as its relative major scale. However, we start on the sixth note, known as the Aeolian mode. Because the sixth is a minor any song using this scale will often have a sad or melancholy feel to it.
Degrees : C (I - tonic), D (II - supertonic), E♭ (III - mediant), F (IV - subdominant), G (V - dominant), A♭ (VI - submediant), B♭ (VII - leading tone)
