  • A Lower Beta Angle and increased cup depth will cause a mouthpiece to have more cup volume and enhance the lower partials in the sound.
  • Lower beta angles are usually found in the design of flugelhorn mouthpieces.
  • This angle of course must match all other aspects of the design to achieve desired results.
  • In the past a cup with a lower Beta Angle was referred to as being more "V" shaped.

  • A Higher Beta Angle and less cup depth will cause the mouthpiece to have less cup volume and may cause the mouthpiece to speak more quickly due to the sound wave reflection back to the chops.
  • Once again, this must match other design aspects.
  • Old school definition would be a more "C shaped cup".
