No obvious ii-V patterns detected.


  • Striking modulation from Ab major to B major via a Gm - F#7 (V7 of B) progression, presenting an unexpected tritone-related dominant.
  • Elegant re-entry to Ab major’s iiø7-V (Bbm7b5 - Eb) after the B major section, creating a sense of returning home.
  • The dramatic, non-functional chromatic shift from Eb (V of Ab) to E major, before abruptly moving to Bbm7b5, creating significant tension.

Improvisation Focus: Targeting arpeggios and scales of new key centers over abrupt modulations.

Difficulty Rating: 4 (Advanced Intermediate). This piece demands proficiency in navigating unexpected key changes and incorporating dramatic non-diatonic alterations.
