Re: how do i bend a note?
Man, if you want to hear a sax player bend a note, get some Johnny Hodges. He can go up an OCTAVE with just bending it.
Most generally on saxophone, you bend a note with your jaw, move it down or up, but to get a serious bend like more than a whole step, you need to learn to do it with your throat. I used to be able to go up about an octave, but I quit doing it because it hurts so bad. You have to tighten your throat so much you feel like you're about to gag.
You could try practicing the bend with your jaw just on your mouthpiece first, then try it with the sax.
