well really u can start off by buying an essential elements book from your nearest store. websites aren't as good a resource as the books b/c the books tell u not only the buttons for the note, they tell u how to improve the note and ur sound, things websites neglect to tell to begginers
besides this site these are the two sites that helped me the most when i spent hours scouring the net for information on music theory and saxophones.
did you do the 8notes free lessons? woodwind.org/sax/
finger charts ect should help you out.
if you got any good links on the subject post em please im a noob too.
