Very little of what is commonly taught about brass embouchures is based on hearsay or descriptions on playing sensations. This results in a lot of contradictory advice that isn’t always grounded in fact. That’s why it’s very exciting to me to see Hans Boschma, Kees Hein Woldendorp, et al, taking a scientific approach to studying brass embouchure. Even more importantly, they recognize the need for more research and more communication across disciplines. They recently published a video that describes their research and shows a lot of the data points they’ve collected. The call it the CODE of Embouchure.
CODE stands for Classification, Observation, Diagnosis , and Evaluation.
The CODE of Embouchure can be used by both brass players, their teachers, ‘brass-medicine’ physicians and – therapists. The CODE of Embouchure can be used in intervals of time to detect dysfunctional embouchure and/or to control for improvements/ changes in embouchure due to brass training (or therapy) e.g. at the conservatoir or in a therapeutical setting. In the final part of the movie a practical instruction is provided with the voluntary participation of many internationally known first rank brass players.
I’ve been skimming through it, skipping ahead after watching some of each brass player shown. Most of it is detailed video footage of different brass players playing a wide variety of different things with some written commentary on different embouchure characteristics. There are many good examples of “medium high placement” and “very high placement” embouchure types. Assuming that the brass players shown are a somewhat random sample, I would expect to see few “low placement” embouchure types. There is one trumpet player who I suspect may be a “low placement” upstream players, but it’s a bit hard to say for sure with what I saw (he definitely switches to downstream when he plays pedal tones). Other than that example, all the rest of the brass players belong to one of the two basic downstream embouchure types.
Overall, I think it’s very nice research and a good video. My main complaint is the lack of attention on upstream brass embouchures, but perhaps that’s my personal bias as a “low placement” type player myself. Also, most of the video is devoted to “observation” and I would have liked more discussion about the “classification,” “diagnosis” and “evaluation” parts. Minor quibbles aside, thanks to Hans Boschma and Kees Hein Woldendorp for posting this and for Hans for letting me know it was available.
