A brand new development from Donat mouthpieces, in collaboration with Ko de Rooij: Tone-Ring mouthpieces, available for cornet and flugelhorn, designed to give an unmatched combination of sound and playability. Along with a unique new design, adding a Tone-Ring to the cup, a shorter heavy blank has been developed for improved tuning. Characteristic for the Tone-Ring mouthpieces is a big and rich sound, maintaining its integrity with clean articulation at all dynamics, throughout the range of the instrument. The Tone-Ring concept really is a game changer. Try it to believe it!
