Sweet models

easy to play

The Donat standards for the small bore trombone have a slightly shorter blank, to make it easier to “let it play”
The models for large bore are slightly heavier, to add presence to the sound.
The inner rim is progressive for a larger contact area on the lips and greater endurance.
The rims of Atelier Donat provides flexibility and comfort to allow the musician to perfect his playing.

Good to know

Small bore trombone mouthpieces are engraved with a capital “A”
