Thanks Milandro. Yes, the height when the front F opens is not the ideal height. The same goes for F sharp.there is the possibility that the way the front F opens is not the ideal height on your friend’s saxophone but much of the altissimo depends on how you produce harmonics.
Assuming that your friend has no problem to produce altissimo then it is likely that he is used to his horn while you aren’t.
Some horns play altissimo easily and others are more picky and require getting used to it. Besides, some players never play any altissimo and never discover that said regulation of the front or quick F is off.
Thanks for the update. Out of curiosity, what does older horns mean? Before 2000?well, ultra modern horns the opening of front F is adjustable but on older horns this has to be regulated cutting cork or felt to the desired opening.
On the other hand you can also adjust the fingering of the notes with alternative fingering.
Actually, I had an old Dolnet where you loosened the arm that the front F key bore on, and slid it up or down to increase or decrease the amount of opening. I don't think I've ever seen another one like it.I think ( but I may be wrong It is not a detail that I have ever paid too much attention to) before the '80 no horn had front F regulated by screws.
