I have been watching with dismay some recent online message board conversations about clarinetists picking up the saxophone and saxophonists picking up the clarinet. I am of course a big supporter of doubling, but much of the discussion seems to center around embouchure, and the language used is not only misleading but also vaguely pejorative. Clarinetists seem to regard the saxophone embouchure as “loose,” a term I think most saxophonists would take exception to, and saxophonists consider the clarinet embouchure to be “tight,” a concept I would expect clarinetists to shy away from.
I am not aware of any difference in looseness/tightness between the embouchures of the two instrument families, and can’t think of a reason why there should be one. In both cases, the embouchure—the lips and surrounding facial muscles—need to be “tight” enough to form a non-leaking seal around the mouthpiece and reed, and “loose” enough to allow the reed to vibrate at the desired amplitude (volume). The most common looseness/tightness problem I see in teaching both instruments is excessive tightness, often used in an attempt to compensate for pitch stability problems caused by poor breath support, and resulting in sluggish response, restricted dynamic range, and stuffy tone.
The DS538B appears as though I could disassemble it with an adjustable wrench; it’s tempting to attempt this and spray-paint the yellow parts black. (I can only assume that attempting something like this voids applicable warranties.)
