Step-by-Step Guide
1. Learn the Melody by Ear – Key C, first note G.
2. Swap in Jazz Colors – Cmaj7 (LH C | RH B–E–G), A13 (LH A | RH G–C#–F#), Dm9 (LH D | RH C–E–F), G13 (LH G | RH F–B–E).
3. Keep Melody on Top – Adjust voicing so melody note is highest.
4. Add Passing Chords – Between Dm9 and G13, try Ab13 (LH Ab | RH Gb–C–F).
5. Play with Rhythm – Swing feel or arpeggiated chords for variation.
