Hi… usually all beginners’ problems with lower notes are due to lack of “warm air”. Teachers usually call warm air that solid, well supported airstream that comes pushed by the abdomen muscles and exits through a well open throat, like when you’re yawning. Try to practice that consistent breath in a slightly higher note (say C#) then practice a short downscale C#, C, B, Bb keeping a good warm air flow.
You should watch your embouchure as well. Notice that lower notes don’t need too much lip pressure. An unwanted overtone (center B sounding while trying to play low B) could be due to too much reed pressure.

You guys hit the nail on the head. I was working on a song today that had me plAying high B and the dropping to the Lowest B as the next note. I had a B word in mind as I was not hitting that low note rite on cleanly. I was getting all kinds of overtones out of it. Back to the basics for sure!!!

@ Eugene- We’re all here to help/encourage each other…I know with my recent setback I sure needed the help/encouragement. I’m happy to say that letting my Masseter muscle in face heal naturally is already working, the swelling has went down a lot…and I do mean a lot. So it has picked my spirits back up to say the least. The hardest thing for me is to resist the urge to wanna pick up the Sax…right now, suffering a setback is just not worth the risk.
Just remember guys, like Marc is saying, playing in the different registers of the Sax requires adjustments in our Air Support and embouchure. Just to add to his point, it’s important to hear the note before we play it too. Once we fix that sound in our head, it’s becomes much easier to play it because if we’ve been practicing correctly, our mind will tell us if we’re doing it right/wrong and when we do it wrong, then we will know what to do instantly to make the necessary adjustments in our air support & embouchure to hit the note–and that goes for any note were trying to hit… that is, if we’ve been practicing the right things that will allow us to do the things on the Sax that we wanna do. Hearing the notes in our head first is so, so imporant….you would be amazed how much we can change our sound up simply by changing the kinds of music we listen to! That’s how important it is.

Be patient with it Eugene, it’s only been 1 day. It’ll take some time and the more you do it the better it will get for you. You can always upload a quick demo to soundcloud.com It’s very easy to open an account and share the link here to Johnny’s site. Another thing to consider is making a leaky pad on your Sax? That can cause similar problems too.
