Eh, any help on high notes? I can`t play them.

And high C and high B sound the same; any idea why?

Oh yeah and it is high notes as in the first set of high notes after the regular C, D, E, F, G,and A.

Support with a lot of air...this may sound really stupid but are you pressing the register key ( I know some people that didn`t until I told them to). Tight bottum lip, pointed chin. Are you folding your bottum lip over your bottum teeth??? Just some ideas!

It`s a common problem among beginners, so don`t feel too bad. Have a tight embochure (your lips/mouth over your mouthpiece). Stronger strength reeds may help, but the notes you`re talking about should come out fine on any size reed. Make sure you`re not puffing your cheeks, that you have the proper fingering, and your fingers are completely covering the holes. It may take some work, just keep at it and don`t give up.
