Wet the Teeth and Gums
Whether one plays with a totally "wet" outer embouchure, a totally "dry" outer embouchure or any combination (i.e. dry top lip, wet bottom lip or wet top, dry bottom), the vibrating area of the lips (within the cup) will require certain moisture to function properly. The vibrating lips may receive moisture from the air column itself as it passes between the lips or from a deliberate action of wetting the area at times throughout one's playing with the tongue tip. Some performers even wet the mouth corners. "Wetting the teeth and gums" is a worthwhile habit to acquire that will eliminate the "sticking" of intervals, keeping the inner embouchure on track!
Since we all are teachers, whether ultimately "our own teacher", teaching others privately or teaching the youth in a school setting such as Middle School, High School or College level, I will be gearing FixYourBrass to include teachers and performers. My posts will have various "topics" (Range, for example), with information for development and maintaining these categories as well as problems that may arise. The posts may be followed by my own "comments" and as to solutions to these problems watch for follow-up posts. So please add your own comments as to create a dialogue regarding said posts as well as any "personal problems" that I can help with. Looking forward to this exchange.
