Im am have trouble hitting an e on the alto saxophone what do i do?

First answer's correct, higher note = tighter embouchere. If you're really having a hard time hitting the note, work your way up to the note. Start off a few notes lower, like B or C, and then just go up the scale chromatically until you hit E. Once you hit the note try and figure out how to make the note stronger, changing your airflow, amount, or whatever. Sit down and just play around, it'll come with time. If you're hoping to be able to "hit" it later on, as in just attack with it and play it without any precursor, then I would have to say that, in comparison to the B A G just below it, it is a tighter embouchere with a higher, tighter airflow. Honestly I think it just develops into an unconscious understanding, especially as a beginner. I don't know how much I understood airflow direction tips when I first started.
