Nice additions to the instrument articles. Rackett is sure a weird beast! I've played with one occasionally  I don't do double reeds, but I had to toy with it anyway. By the way, when modifying entries like sackbutt, you should check first to see if it automatically goes to sackbut (as it does), in which case there's not much reason to change the spelling (considering how many spellings there are for sackbut.) I assume you're a double-reed player with a fondness for Renaissance horns? ∇∆∇∆
