Remember, tell the musical story you want to tell by what chords you choose, and by what â¦ So ok, fine, so far Miles is saying, "Just in case you didn't already figure it out, I'm playing in D-Minor. Even though Dorian is a minor mode, you can play it over the major chords found in Mixolydian. As you know that every mode has a unique sound quality or emotional identity that is used to incorporate within songs/instrumentals. Remember, tell the musical story you want to tell by what chords you choose, and by what order you put them in. Modes are starting a given major scale on a different note than the name of the scale. No one played like this or knew how to play like this: bebop songs changed chords every two beats---that's two chord changes per bar, and soloists used those changes like a scaffolding on which to hang their solos---and here comes Miles writing a song that stays on the same chord for sixteen bars in a row. While Tu does start on the Gm7, it's a much more "jazzy" progression where ii - V - I progressions abound.
