Trumpet: Setting the Embouchure

   Setting (stabilizing) the embouchure is essential to consistency in performance.  But embouchure stabilization has more than one requisite: properly learned fundamentals, focus, repetition of practice material until it is mastered, sufficient daily practice time and consistent (accurate) application of the material practiced.
   Trumpet playing is one endeavor to remain devoid of political correctness.  Neither apologies nor excuses work.  It is a case of either you can or you cannot.  Close is never sufficient.
   Setting the embouchure is physically impossible so long as any facet in trumpet playing remains in need of improvement.  And to forge ahead before making necessary correction (or development) rewards the player with inconsistency and bad technique.

K Tongue Modified

   K Tongue Modified (KTM) is Claude Gordon's expansion of Herbert L. Clarke's "K" tonguing.  The common denominator to both tonguing techniques is use of the tongue proper rather than the tongue tip.
   Gordon theorized by tonguing in this fashion (KTM) less disturbance would be offered the airstream and result in a more effective upper register performance.
    Like "K" tonguing, KTM requires the tongue tip make contact with the back of the lower teeth at all times.  Unlike "K" tonguing, KTM is used for single tonguing in addition to double and triple tonguing.
   Converting to KTM takes time.  But usually less time for players proficient in "K" tonguing.  It should be noted that KTM requires developing the front of the tongue ("T") to the same degree of fluency as the back of the tongue ("K").
