Hi Mark, thanks for the info. I had found the BetterSax chart, but the video is also really helpful.
I was hoping for a person with the same YAS-62 sax I have, to tell me his/her fingering for G#/Ab.
I have tried Jonas’ Alto fingering but some of these just don’t work on my sax (my lack of skill?)
The Theo Wanne Water MP has made it much easier for altissimo than my other MP’s.
This could be because it requires less air/effort and gives me greater control?
Cheers Jeff
