Hi, I’ve seen several tunes where the progression goes from a minor seventh, to a major minor seventh, back to the minor seventh again. My Funny Valentine is a good example. So is My Way, shown here:
My first recommendation would be to experiment with the inner voice at the top of the voicing, at the bottom of the voicing, and inside the voicing. Check out chapter 4 of this seminar - “the minor line cliché” - where I demonstrate these options for “In A Sentimental Mood”
We also covered this tune in a seminar on “How To Play Like Eddie Higgins” where I share some more advanced ways that Eddie Higgins voices this progression, check that out here:
That will give you an idea of some of the options available to you
