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.)

This was a wonderful session. Thanks to @Dawn Lomax @Malcolm Thornley @Rhonda Smith for the great questions! Special thanks to @Magda Prins-Nip for playing some beautiful Bach for us!
