I’m sorry I can’t figure out how to put this up properly, so you have to click on this link to see the pictures of a pretty “interesting” solution to the lack of a B-flat on most of our English horns. And the guy who wrote the instructions is hilarious:
“You may have noticed in the pictures that the elbow turns the bell 90 degrees from its usual position. Get used to it. Because I play big clarinets with bells, I’m used to stuff sticking out front. Aim the bell at your audience if you want to really let them know when you hit the low B-flat. The white color of the extension is also visually appealing. Black is boring.”
Hmmm. Well, I can’t stand the white, nor do I like the 90% angle. The bigger issue is that you need to be able to go back and forth between low B and low B flat. There isn’t always time to remove the extension … for instance, in Prokofiev’s Romeo & Juliet!) Still it’s fun to see.
