On the track, you will hear extensions of these chords - as is common in jazz of course :)
Scale suggestions:
C minor pentatonic scale - C Eb F G Bb (C)
C minor blues scale - C Eb F F# G Bb (C)
C minor scale -C D Eb F G Ab Bb (C)
Ab7 chords :
Ab Lydian Dominant - Ab Bb C D Eb F Gb (Ab)
G7 chords:
C harmonic minor scale - C D Eb F G Ab B (C)
Or
Treat it as an altered chord and use the altered scale:
G altered scale - G Ab Bb B Db Eb F (G)
The altered scale is the mode which starts on the 7th step of the melodic minor scale, so in other words - the notes of G altered scale are the same as those of Ab melodic minor scale :)
The 7th arpeggios will come in useful:
Cm7 - C Eb G Bb
Fm7 - F Ab C Eb
Ab7 - Ab C Eb Gb
G7 - G B D F
Dm7b5 - D F Ab C
HAPPY JAMMING!
