Harmonic Highlights

  • Frequent modal interchange between the tonic C minor and its relative Eb major, utilizing pivot chords like Dm7b5 to bridge the two centers.
  • Chromatic descending transitions, such as the Am7b5 to Abm6 to Gm7 sequence, which creates smooth linear motion toward the iii chord.
  • Extensive use of secondary dominants (Am7โ€“D7 and Gm7โ€“C7) to temporarily tonicize different scale degrees, increasing the harmonic rhythm.
  • The inclusion of F#dim7 as a common-tone or sharps-four diminished chord providing a chromatic lift toward the Gm7.

Improvisation Focus

Guide-tone targeting (3rds and 7ths) to navigate the rapid cycle of fourths and shifting tonal centers.

Difficulty Rating

3/5. The frequent modulation between Eb major and C minor, combined with non-diatonic chromatic passing chords, requires an intermediate understanding of functional harmony and agile voice leading.
