As I was practicing today, I started to notice that my fingers were super flat against the keys of my alto sax. I know that on piano you are meant to curve your fingers quite a lot, but I'm not sure so much about sax. I've been playing for 6.5 years so I'm not sure why this question only just came to me, but should I be curving my fingers so that I am pressing the keys with the very tips of my fingers, slightly curving them with a sort of natural position, or just leaving them flat. If I do need to change, is there anything I can do (like exercises or something) to transition more easily. Any help would be appreciated
