After some music generalities (what is a musical instrument and a musical sound? What is music?), the author presents a (then) new electronic instrument: the icophone. The icophone is a vocoder that incorporates a visual representation of sound - it can be operated as a text-to-speech synthesiser. The article concludes with an example of visual representation and correspondences between graphical objects and their sound realizations.
