Ok I read a thing on here on how to do circular breathing and I got the part down on how to get the note out while taking in a breath but I can`t seem to get the transaction aferwards. When I get past taking in the breath I`m confused on what to do next, there always is this jolt of air that flows to my mouth and it creates a jerk in the sound and I end up going to the note on that key. Can any of you guys help me out on this?? Thanks!!!

Go to Jack in the box and get the biggest shake. Suck that sucker down without taking your lips off the straw. Pay attention to your breathing. Notice how you are able to create pressure in your mouth even while you are still breathing. Practice that. Once you can do that try it backwards. Don`t even attempt to try it with a horn on your mouth. Just straws and shakes. Soda works too but the pressure needed for a Jack-in-the-Box shake makes it more noticeable. :-) Good luck.

I had this same problem for a while. You just want to make sure that the air stream your pushing out with your cheeks is the same as the one you were doing before. and take as quick a breath as possible through your nose. To stop the jolt, i guess it just takes practice. It happened to me for a little while, but now it doesnt. hope that helps.
