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.
