For next lesson, I'd like to know how to compensate for a certain issue.
With some reeds, the 2nd octave E and G are unstable. Holding down the low B flat key remedies this. Turning the reed over helps sometimes. Do you know of a permanent fix? Is it a simple adjustment to make? It only happens with these 2 notes... and only on certain reeds.
(Oboe had a tuneup two months ago.)
