Topic: That D above the staff and double tongue
First I want to say I wish I was with all of you in the conference! I had so much fun last year in Oxford. We are in the last week of the season with a Wagner gala, fun fun fun! I shouldn't complain, at least we had a season and what looks like a great one with our new director next year, the Spanish economy has not been kind to its orchestras.
Anyway, I saw a post from Vincent Ellin from 2006 about the overblown D. That is a serious problem note on Buffet system bassoons, I usually use the RH Ab key. On my Heckel the RH Ab does raise the pitch, but it is quite high, I like adding the RH 2 3 and F that Vincent mentions, for a reliable ppp attack, it is a good fingering. You can use the fingering in Haffner to raise the pitch of the staccato D C# bit, the RH works for both notes if you use long C#. RH 3 and F is yet higher in pitch and also helps raise the pitch further. I have also found adding the RH Bb key by itself also helps raise the pitch. This fingering is especially useful for double tongue passages, again, like in Haffner, and if you use the short C# fingering. I find the pitch way too flat on a double tongue D and the technique is easier with the Bb key and you can leave it pressed down for the short C# fingering. My students have had luck with adding the Bb. I actually had an audition committee member ask me why the fast staccato D and C# section is always so flat and why don't we bassoonists just fix it.
