Here is a nice solo break Mulgrew Miller uses over a dominant 7th chord. He starts on the #11 and runs down the altered scale until he gets to the second measure. At this point he has a nice skip pattern he uses to get back in to the altered scale at the C natural being the #9. He then finally resolves down to the A D A. Practice this solo break for the dominant chords and make use of the altered scale in your solos and breaks. Enjoy!
