I just rented my alto sax yesterday and when i tried blowing on the mouthpiece no sound came out. i tried replacing the reed and moisting it too but still no sound besides a brief uncomfortable noise/ i don't think its the sax cause i have this problem with it unscrewed from the saxophone and on it. any idea whats wrong with it? a couple things i did was place the reed just slightly over the mouthpiece cause i thought thats what you were supposed to do and i actually wettened the hard end of the reed that your mouth doesn't touch instead of the thin end. could that be it? I just started Btw, still learning.
