Hey guys =P

When i play the alto sax and try to breath in to stomach, after a while i start feel like thru up or uncomfortable/hungry
even when i alredy ate.. do i try too hard or something? i really start not to like breath thru my stomach lol

i played 1 year when i was younger, prbably 13-14 year old, but i barely trained 2-3 times a week but now i start again and train 5-20 minutes in 3-6 times a week, and been doing that for about 4-5 month now.

Got some more questions... is there other way strenghin my muscles around the mouth? then just play?
And how to vibrate? i have been trying to searh on google and askin my sister who has exp in alto sax for 3 years but she dont know how to explain it.. -_- i also know that you vibrate on the bottom of the lungs but does it just come itself? is there no exactly way to learn it? THanks .. hope i get some help and sorry bout my spells =P

And also.. my tum hurt when i have play a while, i wonder if its because i can bow it faar back that it hurt?
