I've been tutoring trumpet for about a year now, and one beginning student is quite a challenge. He started weekly half-hour lessons in February and is still stuck with an airy tone, especially as he rises above ~F-G on the staff. As for range, he can make it up to about ~D-E (top of staff). He is 50 years old, has a great attitude, and is very determined, but his irregular work schedule sometimes prevents him from practicing systematically (his goal ~ four times per week). He sometimes takes his mouthpiece on trips, but it drives his wife crazy. At first, he bought a used Bach Strad, and I thought the problem was just the horn--simply too professional with too narrow slotting, like putting a beginning driver in a race car on a banked speedway and asking him to drive 200+ mph without crashing. He then rented a Getzen that retails for ~$700-900. Somewhat better results, but still no consistent, clear, solid tone as he moves toward upper register--very airy. We have worked on proper breathing and opening the throat, we have done long, low pedal tones, we have done scales, arpeggios, and songs. We have buzzed w/o mpc and with it in front of a mirror. We have discussed Gordon's drawing of how the lips contract within the mpc (Systematic Approach..., p. 5). Finally, I decided to try to reproduce, for myself on my horn, his airy tone, and to my surprise, I did it! When I rolled out the red part of my lips and placed them together evenly (without overlapping the upper one over the lower one), I got his airy tone. Eureka! It's simply the embouchure, I thought, not the horn, not the breath control, not a closed throat. But he thinks it's not so much the positioning of his lips. He thinks it's just lack of strength in his lips and facial muscles. They're weak. So now what? Last week I bought Warburton's P.E.T.E. (Personal Embouchure Training Exerciser) for myself. If it helps me, I'll recommend it to him and my other students. Also, I've ordered Jeff Smiley's book, "The Balanced Embouchure," to see if the answer lies there. And finally, I've joined Trumpetmaster so that I could post this puzzle to you guys. Would appreciate your comments, suggestions, and stories of your own experiences. Thanks.
