Hi, I`ve been playing the clarinet for
about 7 or 8 years and I always tried to go higher, like anybody of us will do, just to see how high I could go. But before, I was able to go to E6, and now to D#7 (with alternate fingerings)...but now, there`s just a "blank section" where anything sounds.
From E6 to F#6...really nothing came, even with strong efforts, and when I jum to higher notes, it just sounds perfect... any suggestions?

p.s. Sorry If my text isn`t well-written..it`s because my mother language is french...
