I thought I had posted this video before, but when looking for it here I couldn’t find it. Here’s a video of tubist Oren Marshal, of the London Brass, in a rehearsal. Look at his chops closely and see if you can guess his embouchure type. My guess after the break.
Definitely a Low Placement embouchure type. Upstream tubists, like Marshal, need to have a large enough chin to place the mouthpiece so low. You can see in the video how great his embouchure is working. It’s a good example to show anyone who thinks that upstream embouchures are just a trumpet thing or just a jazz thing. You can find great upstream players on all the brass instruments and in any genre of music.
Definitely an upstream low placement embouchure, classic Reinhardt Type IV.
