The euphonium requires a mouthpiece capable of combining breadth, stability, and comfort across all dynamics.
The DONAT collection for euphonium has been designed to offer natural playing, easy response, and controlled projection, while preserving the warmth and depth characteristic of the instrument.
A focused range, designed with care, to support both musicians seeking flexibility and those who favor power and stability in the sound.
Choosing your mouthpiece
Choosing a mouthpiece means finding the right balance between diameter, cup, throat, and mass.
To support musicians in this choice, we have gathered several simple reference points, each explained in a dedicated section.
You can therefore:
– choose your diameter, according to your natural comfort and your playing goals;
– choose your plating, according to your feeling in contact with the metal and the level of maintenance you prefer;
– consult the cup information, to understand depths and their impact on the register;
– consult the mass information, which influences stability, precision and the way the mouthpiece responds;
– read our advice on how to play your mouthpiece, in order to obtain a free, regular and comfortable vibration.
– explore the most popular models, to discover the sound signatures that work best among musicians;
These elements will guide you toward the model that best matches your playing style, sound aesthetic and way of shaping the vibration.
The models
Custom mouthpieces
DONAT is one of the very few workshops capable of offering true custom work. This demanding expertise is built on years of research, prototypes, and collaborations with musicians of all levels.
It is important to clarify that the DONAT workshop never makes copies: we do not reproduce mouthpieces from other brands, and we do not attempt to “imitate” external models. When a musician wishes to approach a particular sensation or aesthetic, the workshop guides them toward personalized work built exclusively from DONAT models.
Custom work is therefore not a blank starting point, nor the reconstruction of an existing model. It is a controlled variation, based on the acoustic stability of the catalogue. Starting from a specific model, we may adjust a rim, refine a cup depth, modify the cup–backbore combination, adapt a throat or a mass. These are subtle workshop gestures, precise adjustments that cannot be achieved through simple imitation.
To guarantee this balance, every custom project begins with a Premium Trial. The musician first chooses several catalogue models that approach their intention. These trials allow us to identify what works, what should be preserved, and what needs to be adjusted.
Only after this stage can the workshop create a custom model — work built on real playing sensations, not on an abstract idea or a requested copy.
The DONAT custom approach exists only because the workshop possesses:
– a large and coherent catalogue,
– a refined understanding of acoustic balances,
– rare craftsmanship and in-house manufacturing.
This is the rarity we wish to preserve: personalized work that remains faithful, respecting both the musician’s vibration and the DONAT sonic identity.
