Étape 1

Acoustic research

Jérôme Wiss has taken a new approach as a brass instrument maker by the use of very advanced acoustic calculations and computer modeling. Jérôme Wiss’s instrument designs always start with an acoustic study. This step is important because the geometry of the instrument bore defines their accuracy, their musical color, and tone.

Current state of the art tools are used to calculate the frequencies that the instrument generates before they are physically created. Virtually design instruments are free from material constraints. This way of working offers a complete freedom and an opportunity to test infinite instrument shapes until you find a nearly perfect sounding body.

All Jerome Wiss instruments require this study, which ensures you to have a truly unique instrument.

Étape 2


Once the acoustic study and the geometry of the bore of the specified instrument are complete, the instrument is designed in 3D CAD software. This allows the entire instrument to be rendered, and lets us know the measurements of each part before production starts. This design process enables the production of tools and dies so future instruments can be manufactured. It also facilitates modification of ergonomic and aesthetic requirements before final fabrication. This results in a perfect replication of parts, quality control, and stability in the production range. Thus, all products are exactly the same instrument.

Étape 3

3D printing prototype

Once the CAD drawing is complete, the prototype is made on a 3D printer so we can test its function, and make any changes before making a final prototype. This method of instrument design also offers the advantage of reducing the environmental impact by minimizing losses in fabricating many brass prototypes.

Étape 4

Testing the instrument

Once the instrument is made, the final frequency calculations of the resonating chamber are plotted on an impedance bridge. This verifies that the theoretical calculations in the design phase, and demonstrates the accuracy of the digital design on the final instrument.
