Altissimo fingerings

I myself need to practice these and continue to learn new ways to play altissimo notes. The fingerings for them can be hard to find and remember. I thought that this fingering chart was pretty good, though I plan to print it and draw in open/closed circles to make it more readable. For those of you who don't know, "altissimo" is the highest range of the clarinet. There are several fingerings for these notes giving players almost endless possibilities. Each player should experiment with all the fingerings to find one that plays in tune or makes a technical passage easier to play.
