Part 6/9:
Throughout his interpretation of "Donnelly," Jaco integrates bebop language, quoting Charlie Parker and imitating Parker’s improvisational style. His use of extended and altered chords, tritone substitutions, and melodic phrasing illustrates how Jaco bridged traditional jazz language with the electric instrument's modern potential.
The detailed description of specific licks—such as outlining flat major chords, using tritone substitutions, and chromatic walks—reveals how Jaco’s playing is deeply rooted in bebop traditions but also pushes boundaries with his fretless expressiveness. His inventive harmonic vocabulary and phrasing evoke the complexity and sophistication of Parker’s solos, reimagined through the electric bass.
