The Relationship Between Median and Sub-Median in Music

A major or minor chord is just the space of half the octave. Plus half of that half or a quarter. We did split the perfect fifth in two, giving us two quarter octaves. It's the other quarter that the sub-median represents. The median defines and affirms the quality of the scale. And the sub-Median throws in some counter-vibes. When it comes to intervals and how they interplay, what counts for chords, counts for melodies,. They are the same counts after all.
