started playing bari sax about 9 months ago, been playing alto for about 2.5 years and for bari i am struggling to hit any notes from low F down and sometimes even the middle D, E, F range too
(the sax has been serviced and checked multiple times so i doubt its to do with the instrument so....)
when i started out i used a 3.0 rico reed (because it was all i had at the time) and was actually fine playing most notes, including the lower range (but didnt sound very good as i was still getting used to it). now i have been playing for longer and switched to a plastic reed as i was gifted and when i tried it it seemed more comfortable to play with (any reason why??) but now am struggling with the lower register and some other notes
when i try to play lower lots of different things happen its rly weird usually it will jumps up one octave, sometimes two, sometimes i swear it jumps up an octave to a completely random note (but not squeaking) or just does not make any sound. i have read about loosening my jaw and embouchure (but i was never really taught about like face muscles and stuff) but i dont struggle at all to play the low register on alto so i am quite confused :( also i used a neck strap if that changes anything
any advice would be great cuz i rly feel like im not improving at all ty
(also idk if its like supposed to be like this but when im playing high G up the sound changes a lot like it feels like it becomes really really airy and light compared to like a middle D which has a bit of a raspy kinda sound...?)
