I was just thinking about how blowhole shapes and undercutting differ so widely from maker to maker of wooden flutes…thus requiring of the player different embouchure and blowing technique. Is this the case at all w/ Boehm flutes, or are things pretty standardized..(i.e. Are the holes all pretty much the some, and do people have to adjust their embouchure and blowing when playing other makers’ flutes). Just wondering 
Embouchure holes vary widely on Boehm-system (silver) flutes.
There is at least as much variance as on Irish flutes, maybe more.

Quite true, Boehm embouchures can be very different. You can have square, really square [bleah], oval, sharp dropoff past the hole (or not), varying styles of undercutting and heights of risers, differrent sort of metals in the risers and lip plates, wings [double bleah] or no wings and, lets see, what have I missed?

It’s nice to have the choice on the Boehm flutes, b/c you can get different headjoints “fitted”, thus hugely improving your existing flute.
