Digital music instruments and sound expression

The main goal of this paper is to describe certain aspects of the construction of a prototype, while introducing generally some of the key issues resulting of the design of its interface. The word LeinKlang (from the German) means sound (Klang) screen (Leinwand). This project consists in the construction of a digital music instrument. Physically, it appears as a screen, against which users interact, by shadow or video projection, and behind it, intentionally out of view, a set of 24 small loudspeakers.
