Well... Lately my Altissimo G (Four ledger lines above staff) Has been coming out really screechy or really sharp and if I alter my Emboucher it goes really flat... Any one know of any good ways to Improve? this is including the altissimo A above the G

Try some different reeds and double check to make sure your tongue is making the right shape inside your mouth.

you can also ttry some alternate fingerings, or just try adding or removing a finger~ it may help

Great idea, kato. Are you using the Eb key? This could help. Have fun!

thanks!
for the G ive recently begun using

with the pinky 4, and thumb and register keys - this is most in tune for my clari, and i find easier to play too

hope this helps

depending on what kind of clarinet you play on, the fingerings will vary. Try this one

and put down the Eb/Ab pinky key...that one is very clear and in tune for me
