What's Your Favorite Chord Progression as of Late?
Lately, I find myself writing melodies over the 1–b3–b7–B6 [Editor’ Note: Am7-Cmaj7-G7-Fmaj7] progression in a minor mode with all diatonic seventh chords. The voice leading within the chords is super smooth and I can write melodies of a few different moods over the same chords.
