Got it out of a solo transcription (tune: Hark).
In the solo he used it over a Dominant7 Chord but i prefer to memorize it as minor lick ;).
You can also think this underlying chord progression | D-7 A7b9b13 | D-7 |.
Great if you have a major chord for two or more bars.
The basic shape of the line is just a broken major triad.
Charlie often used approach notes in his playing.
A nice example how powerful this could be.
1. Chromatic approach from below to root, 3rd or 5th of the triad (start where you want)
2. Next chord tone above, diatonically approached from above
3. Repeat it (next chord tone below “1.” approached chromatically from below and so on…)
