5MM Throat Size Reference: Trumpet, Cornet, Flugelhorn
The 5MM Throat regulates air flow and is a major factor in the harmonic overtone color produced by our 5MM Modular Mouthpiece System. The larger the throat, the greater the overall dynamic and tonal range.
Most standard mouthpieces have throat measurements in the range of .145 to .165 with an end diameter of .20 to .22 inches. A 3C is typically .147 by .21 inches and is designated as F147.21 as in the example illustration.
