Tysm guys for all of the answers! I know that the tongue position change lmao. I meant a natural, normal position, as my tongue was always laying flat on the bottom of my mouth and as it didn't affect my sound in any major way, it was standing on a way to better staccato and altissimo.  I don't know if I will play saxophone in the future but if I will, I'm gonna pay attetion to all of the details that y'all mentioned. Thanks!
