Here’s another guess the embouchure type YouTube video, from “ptarus.” He posted the following short video of him playing a slur over four octaves on trombone with a very good look at his mouthpiece placement and embouchure motion. Take a look and see if you can guess what his embouchure type is.
If this is you (you know who you are), you’re not allowed to guess!
Definitely a Very High Placement type. His mouthpiece placement is pretty close to his nose, but more importantly you can easily see him pull the mouthpiece and lips together down to descend and push them up to ascend.
Very strong playing. Nice job, “ptarus.”
