I just got a new YTS 62II and am trying to hit some of the altissimo notes just above the normal range (F#) of the horn (G through C). I've tried a number of fingering charts recommended online and can't seem to get those notes. I seem to hit tones high above that area, but can't get that "lower altissimo" area. I'm using the stock 4C mouthpiece that came with the horn, and Java 3 reeds. I know each brand/model of sax has its "favorite" altissimo fingers, so I thought I'd post here in the Yamaha horn section. Any suggestions?
