Harmonic Highlights:
- Prominent tonicization of the bIII major (Emaj7) via its ii-V (F#m7-B7), establishing a brighter, temporary tonal center.
- Frequent deployment of secondary dominants and ii-V progressions (e.g., G#m7b5-C#7b9 to F#m7) constantly shifts temporary tonics.
- The F#7#11 chord functions as a Lydian dominant (IV7#11), adding a sophisticated, bright dominant color.
- A sudden chromatic shift to Fmaj7 creates a distant, non-diatonic harmonic surprise, characteristic of Jobim’s unique voice leading.
Improvisation Focus: Altered scales for dominant function.
Difficulty Rating: 4 (Advanced Intermediate). Requires a strong grasp of secondary dominants, altered chords, and navigating rapid, often distant, harmonic changes.
