Dr. Mark, I simply presented data as and how it became available to me. We have enough members that can navigate the german language, so maybe you can get some help there. I wasn't trying to be smart ass. The data is VERY interesting. I don't read arabic, so the chance of me even being able to judge the quality is so low that I probably wouldn't present anything unless it was very graphic (in a scientific way of course). Criticizing the ability to read a CT or the endoscopy data without having read and understood the conclusions (or even knowing who the people were and there qualifications) doesn't help make any point. The chance of me finding time anytime soon to help those not strong in german is zero. I would prefer to invest my time before and around Easter in more practicing. Maybe some of you out there have some time and the skill. The arguments are very powerful and the images too the point. There is a lot of stuff still uncovered and I will be talking to them about adding a chapter. As far as my take on the tongue, I thought that I detailed that fairly early on. With my standard Bb, C or picc instruments, I notice little tongue except articulation. My tktktktktkt seems consistent in any octave. On the baroque or natural trumpet, I notice the tongue fairly high in the mouth and also notice its use for liptrills. The difference could be fine tuning as on the nat the notes are VERY close together. On instruments that many consider standard, I have the impression that the lips are doing most of the work. I don't think about tongue position except abstractly here. The data that I quoted seems to support my "feeling", but interpretation of scientific data is not a knee jerk thing. It takes time to understand and I will interview the doctors (in german) and see what else that I can glean.
