I'm giving lessons to a high school student who is suffering from a stuffy high A and he claims that the surrounding notes aren't. I played his horn with my mpc but it wasn't stuffy for me. I believe it is either his reed or embouchure, but he didn't mention it until the end of the lesson so we didn't have time to discuss it. What are some other possible causes of this and ways to troubleshoot?

Thanks

Sometimes the bis key may not be closing all the way. Since "C" can be an easy not it may be more noticeble at the "A". Also, make sure there isn't some sort of leak at the octave pips.

My A seemed that way too. I just played a lot of music in the upper register with A's included and without paying too much attention to it, it slowly went away with time. I don't know if this is a coincidence in embouchure or horn.
