A thread on the Facebook Trombone Pedagogy group lately has been discussing different thoughts on coordinating breathing with setting the embouchure and placing the mouthpiece. I thought I’d take this opportunity to discuss my preferred way of teaching students to coordinate air and embouchure together, based on Donald Reinhardt’s instructions from his writings, including his Encyclopedia of the Pivot System.
While the jaw is in its playing position, form the saturated embouchure with ALMOST buzzing firmness, so that the lips are “just touching” at the vibrating points. When in doubt, form the lips as if to buzz. . .
Place the mouthpiece upon the embouchure formation as just prescribed and use sufficient “contact pressure” to locate and sustain its position in the playing groove of the embouchure. The actually placement must be executed in accordance with the [embouchure] type. . .
Inhale the high-pitched, whispered “IM” (not “OM” or “UM”) through both mouthcorners – NEVER THE MOUTHCENTER – simultaneously. . . In short, eliminate “gear shifting” and inhale with a minimum of embouchure distortion.
At it’s heart, Reinhardt’s advice is to work towards unifying the player’s pre-playing sensations with the playing sensations. In other words, he felt it was valuable to have as little change as possible in the position of the lips and mouthpiece upon the lips from inhaling to playing. In order to encourage this, he instructed his students to practice (during certain exercises – not during rehearsing and performance) to firm the lips as if buzzing first, place the mouthpiece on the firmed lips, inhale through the mouth corners while maintaining mouthpiece pressure and holding the lip center just touching, then commence blowing by coordinating the mouth corners snapping into their correct position. Taking breaths in the middle of phrases is to be simply a matter of continuing to breathe through the mouth corners while keeping everything under the mouthpiece rim and inside the mouthpiece should remain more or less in playing position.
Many players, including some excellent ones, either don’t consider their embouchure when breathing or are so focused on moving lots of air that they don’t feel that minimizing the embouchure “gear shift” between inhaling and blowing is valuable. Some players will open their mouth very wide to inhale and the mouthpiece placement shifts slightly every time they begin blowing. Some players will set the mouthpiece on relaxed lips and firm them only just as they begin blowing, which can result in twisting or winding the lips up under the rim or distortions and inconsistency in their overall embouchure formation from breath to breath. Consistency in a player’s embouchure formation should result in better playing consistency.
One of the biggest challenges to adopting this approach is that it’s difficult to take in as much air as quickly when you’re only breathing through the mouth corners. Trumpet and horn players may find the smaller mouthpiece size makes keeping the lip center just touching inside the mouthpiece while inhaling to be easier than low brass players with their larger mouthpieces. I think it’s important to keep in mind that this approach is meant to be practiced only at specific times in your routine and then forgotten about while you move on or are performing. We can think of this approach as an ideal goal, but that not every playing situation is going to make that ideal work at every moment. By aiming towards the ideal in your practice you are minimizing the potential for this to cause issues, both short term cracking notes from time to time or the longer term (and fortunately rarer) embouchure dysfunction that can result.
