hi i`m twelve and im makin so much squeks and i cant play notes higher than a G. can anyone help me?

If you play a single reed instrument, make sure you don`t use cracked, chipped, or old reeds. Also, make sure you use a size and brand of reed that is suitable for your needs. If you are a beginner, I would recomend a Rico symetricut size #2 or #2 1/2.
