Renold O. Schilke had a profound influence on the development of brass mouthpiece design and pedagogy in the 20th century. His wisdom and insight have influenced several generations of performers, educators and students while setting the standard for other manufacturers. Today, Schilke Music Products continues to offer the highest level of expertise in assisting musicians when determining what mouthpiece might work best for their playing needs. A mouthpiece is created of several components or variables that greatly influence a player’s sound. These variables include rim contour or rim shape, inner rim diameter or cup diameter, cup shape or cup volume, the throat, the backbore and shank or stem. All of these components play a major role in the final sound production on a brass instrument. General knowledge of these concepts and how they work can only assist the player in selecting equipment that improves their sound.

  • Model number: The model number references 4 areas—Cup Diameter, Cup Volume, Rim Contour, and Backbore
  • Cup Diameter: Smallest numbers are the smallest diameter; diameter sizes increases as the number increases Cup Volume: A—Small, shallow; B—Medium Small; C—Standard, medium; D—Medium Large; E—Large
  • Rim Contour: 1—Roundest; 2—Semi-Round; 3—Standard; 4—Semi-Flat; 5—Flattest
  • Backbore: a—Tight; b—Straight, slightly more open; c—Standard; d—Medium-Large, slightly curved out; e—Large; x—Piccolo, Extra Large
  • Finish: Silver plate

12A4a: 16.71 mm, .658" cup diameter; 27 throat. Similar to the 12B4, but with a shallow A cup and tight a-backbore, which adds both endurance and range.

It’s a perfect shoe without the correct width it needed to be wider
Size: 5 Big Kid, Color: Lavendar
The app suggested a 6.5 but I needed it in wide and it was not an option. I had to send them back because they were too tight!
