Editing Embouchure (section)

===Tongue-controlled embouchure===

This embouchure method, advocated by a minority of brass pedagogues such as Jerome Callet, has not yet been sufficiently researched to support the claims that this system is the most effective approach for all brass performers.

Advocates of Callet's approach believe that this method was recommended and taught by the great brass instructors of the early 20th century. Two French trumpet technique books, authored by Jean-Baptiste Arban and Saint-Jacome, were translated into English for use by American players. According to some, due to a misunderstanding arising from differences in pronunciation between French and English, the commonly used brass embouchure in Europe was incorrectly interpreted.{{Citation needed|date=December 2008}} Callet attributes this difference in embouchure technique as the reason the great players of the past were able to play at the level of technical virtuosity which they did, although the increased difficulty of contemporary compositions for brass seem to indicate that the level of brass technique achieved by today's performers equals or even exceeds that of most performers from the late 19th and early 20th centuries.

Callet's method of brass embouchure consists of the tongue remaining forward and through the teeth at all times. The corners of the mouth always remain relaxed, and only a small amount of air is used. The top and bottom lips curl inward and grip the forward tongue. The tongue will force the teeth, and subsequently the throat, wide open, supposedly resulting in a bigger, more open sound. The forward tongue resists the pressure of the mouthpiece, controls the flow of air for lower and higher notes, and protects the lips and teeth from damage or injury from mouthpiece pressure. Because of the importance of the tongue in this method many refer to this as a "tongue-controlled embouchure". This technique facilitates the use of a smaller mouthpiece and larger bore instruments. It results in improved intonation and stronger harmonically related partials across the player's range.
