Die röntgentechnischen Untersuchungen sollten klären, wie die innenliegende Konstruktion aufgebaut ist und, ob das Objekt im Laufe der Zeit Veränderungen oder Reparaturen am Klangkörper erfahren hat.

Technical challenge

Determine the optimum position of the object relative to the beam.

Determine the ideal scan parameters (voltage, pre-filtering, trajectory, projection number, etc.).

Obtain knowledge of the instrument’s design.


Analyze the instrument’s acoustics. 

Clarify whether modifications or repairs have been made to the object.

Since the Middle Ages, trumpets have consisted of several cylindrical tubes fitted together and a flared bell with a shape that ranges from conical to hyperbolic. The total length extends to more than two meters. Initially long and stretched out, the instruments were later made S- or loop-shaped to make them easier to handle (e.g. for the cavalry).
The exterior of baroque trumpet MI205 is in the shape of a truncated cone. Its mouthpipe merges into the exterior of the cone at the top. 

The X-rays were to clarify how the interior is built and also whether the object has undergone any modifications or repairs affecting its resonance.
