Yamaha 14B4 Cornet Mouthpiece, Long Shank


The Yamaha 14B4 mouthpiece series is a precise, easy playing and reliable way to compliment your cornet's sound. The 14B4 mouthpiece features a medium-large sized rim diameter combined with a semi-shallow cup depth. This offers tonal flexibility over a wide range, resulting in clarity and power across all ranges. The 14B4 also brings out the lower registers, meaning the cornet can benefit from a wider array of tones. The Yamaha 14B4 is a common choice for orchestras and ensembles due to its practical features.

Semi-Shallow Cup Depth and Medium-large Sized Cup Diameter

The combination of a medium-large sized cup diameter and a Semi-shallow cup depth allows for ease of play and increased tonal flexibility across all registers. This helps produce a focused and direct sound with plenty of focus. A great mouthpiece for use in all ensembles and orchestras.

Semi-Flat and Medium thickness Rim Shape

The 14B4 Mouthpiece has a semi-flat and medium thickness rim shape, which provides more comfort for the lips. This helps increase endurance, particularly when playing in the higher registers for extended periods.

Semi-Narrow Throat

This particular Yamaha Mouthpiece comes with a semi-narrow sized throat. This means that it will produce a crisp and powerful response to all registers of the instrument due to having more resistance than a larger throat mouthpiece.


  • Depth of Cup:Semi-Shallow
  • Diameter of Cup: 16.85mm
  • Rim Shape: Medium thickness and Semi Flat.
  • Throat Size: Medium (3.65mm)
  • Backbore: Semi-Narrow
