Harmonic Highlights
- Frequent tonicization between G minor and its relative major, Bb, evidenced by direct ii-V-I progressions to Bbmaj7.
- The use of altered dominants like D7#11 and G7b9 (V/iv) creates strong tension leading to minor chords, alongside an Ab9 functioning as a tritone substitute dominant or backdoor approach.
- Chromatic passing diminished chords (C#07, D07) add color and tension, with C#07 providing a unique chromatic approach to Cm7.
Improvisation Focus Melodic minor modes to navigate altered dominants and fluctuating tonalities.
Difficulty Rating 4 (Intermediate-Advanced) - The frequent key center shifts, use of altered dominants, and chromatic passing chords demand sophisticated harmonic understanding and a versatile improvisational vocabulary.
