The DW2186 Heritage Series tuba mouthpieces feature a deep, V-type funnel shaped Helleberg style cup combined with added mass near the throat and backbore provides a rich, even and focused sound. The upper walls and rim are thinned to compensate for the added mass. The result is easier articulation in the upper register with a colorful tonal response. From solo literature to large ensemble performance, the Heritage tuba mouthpieces meet the requirements of every musical style.
