Mouthpiece Throat Exponent

GR School
The throat exponent is the math used by GR to design the radius that enters the bore of the mouthpiece from the cup.
 
  • In the past, manufacturers have used terms like "shoulder" or "second cup" to describe this area of the mouthpiece. 
  • By using defined mathematics, GR can design specific rates of change to this area of the mouthpiece, and he knows the playing result before the mouthpiece is play tested.
  • Different exponents match certain trumpets or certain cups.
  • This is invaluable proprietery information. If we know your horn and bell, matching a custom mouthpiece just became a whole lot easier!
