A few months ago I caught up with Doug Elliott and took another lesson. For those who don’t know, Doug’s embouchure types and terminology are the ones I prefer to use here and my lessons and interview with him were important resources for my dissertation. Doug studied from Donald Reinhardt and took Reinhardt’s ideas and developed a presentation of them that makes them easier to understand.
At any rate, at my last lesson with Doug he reminded me of Reinhardt’s “Elasticity Routine,” or at least the technique and point behind it. I have some inconsistencies in how my chops function between my upper register and F3 and below. Glissing without using the slide between partials in this register are helping me make my embouchure function more consistently. They are also pretty good for developing lip flexibility and overall embouchure control.
There was a forum topic on the Trombone Forum that was discussing similar exercises, so I threw together a short video describing and demonstrating what I’ve been practicing. It’s not as good as Doug’s demonstration for me, but I think you can get the point of how the Elasticity Routine works. The exact glisses that you do are not as important as how you do them. Do not let up on the mouthpiece pressure and try to gliss between those partials as smoothly as possible.
I had a couple of pretty good glisses in there and some examples of me struggling to make them sound smooth. They all sound better now than they did a few months ago. The point is not that this should sound good (although that’s what I’m trying for when practicing this drill), but how they help your playing.
