hi,
can anyone help me how to get fine intonation on the high notes of the E-flat soprano clarinet(or sopranino, whatever) especially E5 and above (everything goes right till D#5) considering the MIDI Octave Designation Systems (http://www.music.vt.edu/musicdictionary/appendix/octaveregisters/octaveregisters.html)?? This notes sound flat, nearly 1/4 of tone lower or even more. Can it be from my enbouchure?! If so, what can i do.
Some fingerins or tricks will be helpful.

I`ve been playing B-flat soprano clarinet for more than 20 years, but now someone asked me to play the E-flat clarinet in some solos. Sincerely i can tell all clarinetists that is not a "flatter" job to give someone you care about

Thanks in advance (and if my experience can help anyone please make me know)

So the two instruments do have the same fingerings for the notes in the higher register? Wow, I couldn`t even get them to come out-flat or in tune. I just played E flat soprano clarinet for the first time a few days ago and I`m the principal clarinet in our city`s youth orchestra and it gave me SO MUCH trouble. Could it have been because I was using a size 2 Rico reed? Anyway, thanks in advance. -Jackie
