82.68Level 35 — chromatic mediant bass, static top
Try top:
E.
Bass/harmony:
C major: E = 3.
A major: E = 5.
A♭ major: E is highly chromatic, so choose relationships deliberately.
A simpler two-chord exercise:
C→A major with E common.
C→E major with E common.
C→A♭ major with C common.
Voice-leading solves the root leap.
