Harmonic Highlights
- Features a characteristic I7#11 chord (Bb7#11) over the tonic, establishing a distinct Lydian Dominant sound and contributing to the tune’s “floating” quality.
- Incorporates a iiø-V progression (Em7b5 - A7b9) to the relative minor (D minor), adding a temporary harmonic pull away from the Bb major tonic.
- Utilizes a classic I-vi-ii-V turnaround (Bb6-Gm7-Cm7-F7) multiple times, providing strong, diatonic resolution and stability within the Bb major key center.
Improvisation Focus Precise navigation of altered dominant (A7b9) and Lydian Dominant (Bb7#11) sonorities through appropriate scale choices and clear chord tone outlining.
Difficulty Rating 4 (Advanced Intermediate). The blend of conventional ii-V-I progressions with the specific I7#11 and secondary dominant leading to a non-tonic center demands nuanced harmonic interpretation.
