Here’s a nice sounding chord run I got from Tal Farlow. I use it all the time for both solos and comping. He plays it behind Red Norvo over the 2 chord of Sweet Georgia Brown. Each chord is picked once and held for 2 beats and the last chord is held for 2 bars before it goes to the next chord, which in A would be a D7. Tal plays it over Bb heading to Eb. Hope you can use it!
I’ll try and put one of these quick lessons up once a month. The first one is one of my favorite arpeggios and the chords I visualize underneath it. I drew it in A but practice it in all keys. I like to fill it in chromatically especially the 3 to the 5.
