- The use of IV7 (C7#11) and bVII7 (F7#11) introduces Lydian Dominant colors, functioning as non-resolving or “backdoor” extensions of the G major tonality.
- A chromatic descent occurs via Bm7 - Bb°7 - Am7, providing smooth voice leading from the iii chord to the ii-V turnaround.
- The structure relies on secondary dominants like E7b9 (V of ii) to reinforce the movement toward Am7, often employing the Phrygian Dominant scale for tension.
Improvisation Focus The Lydian Dominant scale (4th mode of Melodic Minor) is essential for navigating the #11 alterations on the prominent C7 and F7 chords.
Difficulty Rating 3/5. While the primary key center is stable, the frequent shift into non-diatonic modal interchange requires precise harmonic awareness and scale substitution.
