Atelier Momo Trumpet Mouthpiece

Brass Lab MOMO Orchestral Series Trumpet Mouthpieces

Brass Lab MOMO's orchestral mouthpieces bring Japanese precision and thoughtful design to the classical stage. Crafted for players seeking clarity, depth, and refined control, these models are ideal for symphonic, chamber, and solo repertoire.

We carry a curated selection of their most popular orchestral sizes—including 3C, 2C, 1.5C, and 1.25C—each built with a carefully balanced backbore and bore size to ensure optimal response and tonal stability. The result is a mouthpiece that plays with remarkable consistency across the range, while offering a resonant core and a clean, projecting sound.

The models available are listed with their corresponding bore or throat size. The 26 bore models come with an M backbore, while the 25 & 24 bore mouthpieces come with a 24 backbore.

Designed and hand-finished in Japan, MOMO mouthpieces are trusted by serious players looking for comfort, precision, and craftsmanship in every detail. Whether you're building your orchestral career or refining your sound, MOMO offers a tool worthy of the task.
