I'm trying to teach my little brother how to play the saxophone. The only problem is I don't play that particular instrument, so it's more like I'm teaching the both of us. In the book that I got for him the fingerings are confusing me a little. Behind the cut are a picture of the saxophone and a pic of the fingering in question. For the life of me I cannot figure out which key this picture means. I've circled in red on the fingering chart the part that confuses me, and circled in red the three keys it could be on the sax and labeled them either A, B, or C. So let me know which key it might be if you know, otherwise anyone have a suggestion for an active community that I might get a better response at?
