This seems a decent introduction. The only thing mentioned that I wasn't really aware of is the effect of the tongue in addition to the lips on the embouchure of higher notes. Can anyone recommend some more info on that?
For embouchure mechanics, I'd highly recommend Dave Wilken's blog. That was his doctoral research focus and he's got a good intro to brass embouchures on his blog [0]. The tongue is usually not as much of a focus when it comes to embouchure, but he does have a post discussing his thoughts about the so-called Tongue Controlled Embouchure [1] which you might find interesting.
Dave has been building on the work Donald Reinhardt started in methodically categorizing embouchure types and figuring out how each type best functions. They seem to be part of a minority in the brass community who actually care to approach things scientifically - I could go on about my own experiences of brass teachers who aren't interested in furthering their understanding of embouchure mechanics, but Dave covers that topic pretty well already [2]. Reinhardt's stuff can also be worth reading, but Dave simplified some of the categories that seemed unnecessarily complicated.
