Based on an Rafael Mendez idea (in his book Prelude to Brass Playing) we have designed a 4 week system for getting rid of some of the problems plaguing a lot of comeback as well as amateur players.

NOTE (2008): This 4 Weeks Guide will never be fully finished. You may still use some of the ideas presented.
(Mendez did not write "Prelude to Brass Playing", it was Edward Gibney. Mendez did some editing.)

”The NATURAL method for playing a brass instrument boils down to the following points: (a) FLEXIBILITY OF THE LIPS (b) STRENGTH OF FACIAL MUSCLES ABOUT THE MOUTH, CHIN AND JAWS  (c) EDUCATION AND DEVELOPMENT OF THE TONGUE  (d) POWER FROM THE DIAPHRAGM.  There are no tricks to this method, nor are there any short cuts. The rules are dictated by common sense; they follow only the principles governing sound production. Lip vibration produce sound; the lips, then must be brought to a soft, pliant, vibrant state whereby the may be easily controlled and regulated.  Control comes with development, training, and co-ordination of the many sets of muscles going to make up embouchure. The tongue, one minute flicking lightly, the next caressing gently, and so on, must be trained for accuracy, developed for strength. The power for brilliant tone, for endurance, must come form the only source – the “powerhouse.”  And so, we arrive at the approach to embouchure training. The whole method of natural playing depends upon your attitude, your work, this next few weeks. This is where you “make or brake.”  This is where hte patience comes in!  You are going to learn how to produce a sound – a good sound! Once that is accomplished, you are on your way; you have the foundation upon which to build successful brass playing. You have heard the expression “Well begun is half done.” Keep that in mind!
