At long last, I'm returning to the blog! It's been a very busy few weeks, but the semester is winding down, and I finally have time again to opine on improv. This week, I'm starting a new "segment" of sorts: "This Week in the 'Shed," which will highlight a snippet of the material I've been working on in the practice room. My first piece for this new segment is a perennial favorite of mine, and one I lifted from John Scofield: the diminished scale sequence.
