A robust baritone built for the marching field.

The Blessing BM-311 Marching Baritone is designed to meet the demanding needs of outdoor marching performances. With a large bore and compact wrap design, this baritone produces a bold, balanced tone that cuts through the mix. It is engineered to accommodate large mouthpieces, giving players greater blowing freedom and control. Whether on the parade route, in the stands or anchoring the band on the field, the BM-311 delivers the power and projection required.
Large Bore and Wrap Design Provide Powerful, Focused Sound
The BM-311 features a large bore and compact wrap design that generate a robust, concentrated tone. The broad interior diameter allows air to flow freely, enabling players to produce a big, resonant sound. The wrap's tight coil helps focus the sound forward, directing it toward the audience. Together, these design elements equip the BM-311 to overcome ambient noise and be heard by all.

Takes Large Mouthpieces for Comfort and Control
With a large shank mouthpiece receiver, the BM-311 accommodates sizeable mouthpieces that provide players greater comfort and command over their sound. The ample mouthpiece chamber gives air more space, making it easier to create a full, articulate tone. The broader surface area also distributes mouthpiece pressure for a more natural embouchure and less fatigue. Players gain enhanced breath control to shape each note as desired.

Volume and Mobility for Outdoor Marching
Purpose-built for marching, the BM-311 delivers the volume and portability required for outdoor performances. It produces a resonant tone that carries over long distances, allowing players to be heard clearly by audiences and judges. A streamlined design makes the BM-311 lightweight and balanced, simplifying marching technique. Its compact size also ensures it is easy to transport and store.

Adds Depth and Richness to Overall Band Sound
With its bold, focused tone, the BM-311 baritone enhances the fullness and color of the total band sound. Its sonorous voice expands the band's range, filling in the gap between higher-pitched instruments and lower brass. The BM-311's powerful projection allows it to blend with the ensemble while also cutting through the mix, bringing extra depth and warmth to the band's overall timbre.
