well said. basically, anyone who blows some air into the sax will get an altissimo note (apart from a pure reed sqweek)
so the art of this range is in learning how to control it.
I also don’t use it to the extend of some other players…
I’ve heard players do scales like crazy up there with so much control.
I can’t really do that very well and never felt I had to but every once in a while there’s nothing like blasting a couple really high ones to break things up. some people say they don’t need to go above a high F or F# but I can’t imagine that being my top note….very limited range.
