Yamaha 11B4 Trumpet Mouthpiece
The Yamaha 11B4 is a silver-plated trumpet mouthpiece belonging to the manufacturer's Standard Series, designed for precision and playability across various trumpet types. It is particularly distinguished by its shallow cup and semi-flat rim, making it a popular choice for performers requiring agility in higher registers.

Background and Design
The Yamaha 11B4 Trumpet Mouthpiece is part of Yamaha's Standard Series, which is developed using advanced computer-aided design (CAD) and manufacturing technology. This approach ensures high levels of consistency and precision in the production of every unit. Yamaha has established a long-standing pedigree in the brass instrument market, and this model reflects their commitment to providing reliable components for both professional and intermediate players.
Key Features and Ergonomics
The 11B4 is defined by several specific architectural features:
- Rim Shape: It features a semi-flat rim, which is designed to enhance comfort for the player, particularly during extended practice or performance sessions.
- Cup and Diameter: The mouthpiece utilizes a medium-sized rim diameter paired with a shallow cup depth. This combination facilitates 'easy blowing' and allows for significant tonal flexibility.
- Throat and Backbore: The medium-small throat is engineered to provide a specific level of blowing resistance. This resistance is intentional, as it helps the player achieve a crisp and powerful response throughout the entire range of the instrument.

Tonal Character and Performance
In terms of sound, the 11B4 is designed to deliver smooth attacks and incredibly precise control. The shallow cup depth makes it highly effective for lead playing or for use with higher-pitched instruments like D, Eb, and piccolo trumpets. The resulting tone is described as crisp, allowing for clear articulation across all registers without sacrificing the power needed for projection.
Target Audience and Applications
This mouthpiece is particularly well-suited for trumpet players who frequently perform in the upper register or those who use specialty trumpets such as the piccolo or Eb trumpet. Because of its comfortable semi-flat rim, it is also a viable option for players who find traditional rounded rims fatiguing during long sessions. It serves as a reliable alternative to other industry standards, such as those found in the Denis Wick or Bach catalogues.
Compatibility and Accessories
The 11B4 is compatible with standard trumpet receivers, including popular models like the Yamaha YTR-5335G or the Bach Stradivarius 180S43. To maintain the silver finish and precision of the rim, players often use protective accessories such as the Protec L203 leather mouthpiece pouch. It can be used alongside various muting solutions, such as the Wallace Eb Trumpet practice mute or Gear4Music Coppergate straight mutes, depending on the performance context.
