Jack, Manny, as always, is right on the money. I just finished reading an article about Arnold Jacobs and Vincent Cichowicz in the most recent ITG Journal related to your question that I wanted to excerpt (Page 30): Emily, I really like what Manny told you. At the ITG conference in Denver, James West echoed this idea about finding an optimal â€œspotâ€ or â€œmarkâ€ where your sound will be the best. He said, "Most noise for the least effort is right on. Yes, the mouthpiece has a place where you get the most sound for the least effort! Once you find this place (just buzzing on the mouthpiece), be aware that once you insert the mouthpiece into the horn, you may hold your instrument in such a way that it changes the angle of this optimal spot just slightly. Thereâ€™s a very interesting article by Sam Burtis (a Caruso Student) called Buzz Off!. I especially like the concept about finding a great buzz on the mouthpiece, and then taking note of the associated angle at which your are holding the mouthpiece when achieving this sound. Many times when the mouthpiece goes in the horn, the angle at which you are holding the horn MAY be different than this optimal angle you found while buzzing the mouthpiece alone. Getting the horn to be in alignment with that angle may help in the ease of sound production on the instrument. Another thing that I notice from your schedule / outline is that you do a lot of â€œskill setâ€ exercises, but you donâ€™t mention any â€œbalance / centeringâ€ exercises. If you take Mannyâ€™s advice and start working from a position of â€œgorgeous soundâ€, it would serve you very well to divide your practice day so that you spend some time focusing on balance / center to cultivate this sound which will carry into your skill set work. Craig Morris talks about this in an article called Fundamentally Speaking which I mention in this link. Itâ€™s a very well conceived way to focus on the important aspects of your playing day (centering must have a prominent / dedicated session each day). Hope these thoughts give you a little more detail to consider!
