How can I play better on my Bari sax?

Question: How can I play better on my Bari sax!?

I'm 13 and today I started playing the Bari sax!. I've been playing the Alto for 2 years and I wanted to switch to Bari so I did!.
What are some breathing techniques that I can use to help me play the Bari better!?
I also mess up a lot because from g and under I can't play the notes right because they're too low!. Please/ Help!!!Www@QuestionHome@Com

It seems hard now but in a few weeks you'll be better!. I play the alto and some bari!. If you have trouble with the air practice taking a full breath in 4 counts and letting it out in 8 counts, then 12 counts, then 16 counts!.
As for the low notes, loosen your mouth up and they should come right out!.Www@QuestionHome@Com

umm i think you can sort of flatten your chin if you wanna play higher and let it loosen if you want to play low notes or unscrew the screws on your headpiece!. Www@QuestionHome@Com
