Ken, The 7b9 is also a diminished chord so the shape that rick showed could be moved around to find any db note. Does that make sense? I guess the answer would partly depend on your f- voicing. Just my .02.
Again, thanks to all who responded with advice and answers. I watched the video that Eddy Davis posted on his youtube channel about a year ago and along with your advice his video really helped clear up the harmonic accompaniment questions. If I scale back and simplify his chords I think that will be a good addition to the horns—whether or not if they actually hear me!
