The "Trombosonic" is a new digital music instrument based on the foundational principles of the slide trombone. An ultrasonic sensor combined with a red laser allows the performer to play the instrument using similar movements to playing a trombone to change the pitch, by moving one hand back and forth even though there is no physical slider available. Furthermore, additional sensors enhance musical expression by gestural movement of the whole interface and by using the breath. Due to its compact size and the lack of a slider, the Trombosonic can be played in many different ways. This inspired us to do an informal evaluation to explore the potential applicability of our prototype in different fields and settings other than music. We identified a certain suitability for old and young people and a new possibility for people with restricted mobility to play such a musical instrument. Further development might include a built-in microphone to use the human voice and an expansion of the synthesizer's features.
