Essential II-7 V7 I Lines/Progressions you must know

This video demonstrates seven essential II-V-I chord progression variations in jazz, including adding altered extensions (sharp 9, augmented 5th) to dominant chords, using tri-tone substitutes (Gb7 for C7), incorporating blue notes on tonic chords, and delaying the tonic chord by preceding it with diminished chords or secondary dominants (Eb7 to E7 flat 9 to F6). These techniques create more sophisticated and interesting jazz lines while maintaining the fundamental harmonic function of the II-V-I progression.
