Reed sorting day. Do you all have such a day once in a while? Wich ones are good, wich ones can go and then I sort them in pitch, sound and flexibility. ( is it normal in other countries to play pitch 442 in wind orchestras and 440 or lower in symphonie and baroque?)

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.)
