Topic: "Flicking" or "venting" overblown C#?
Has anyone had any experience with any method or keywork design that allows for venting of the "short" fingering for C#4? I know of the Weisberg system, which does this automatically, and makes that note as stable as a vented C-natural. But what about on a bassoon without the Weisberg system?
I've been trying to brainstorm an idea for an alternate touch for the D key, to enable venting on this note. Nothing particularly promising has come up yet. Someone else must have thought of this though. I really don't like the sound or technical requirements of the longer C# fingerings.
Try this experiment if you're not sure what I mean though: Play C#4 like the lower octave, but without the whisper key, and use your right hand to hold down the D key. It's a good and appropriate vent for the note and improves it greatly. Just how to do this without massive reorganization of keywork is escaping me.
