Use the C Aeolian notes as your main palette over this Jazz backing track. Keep phrases short and listen for how each note feels against the chord that is currently playing.
A 4-chord progression gives you more harmonic motion than a vamp or basic three-chord form, which means more chances to shape phrases around changing target tones.
This 4-chord progression moves through Cm7, A♭maj7, Bb7, and Gm7. As each chord arrives, aim your phrase endings at notes from that chord. Those target tones are the clearest places to land, and the rest of the scale helps you connect one chord tone to the next.
Start simply: play two or three notes, leave space, then answer with another phrase. Add slides, hammer-ons, pull-offs, bends, or vibrato after the target-tone movement feels clear.
