Abstract:

This paper features an investigation of the interactive electronic extensions of the musical performance, based on an phemenological approach to the human perception of sound in a musical context. The interactive extension of the musical performance offers, through performer control over the produced sound in real-time, possibilities for the composer to take advantage of subtle features of acoustic sound, due to the individuality of the live performance. Richard Leppert understands musical activity as a synthesis of sound experience in accordance with a visual experience: The sonoric landscape. Using this concept investigations about perceptive characteristics of synthetic and human sound will be made, with a purpose of describing the advantages of real-time sound processing. Further, the structure of the interactive process will be sketched, and in the final section a brief overview of a piece, NoaNoa, for flute and interactive electronics by Kaija Saariaho will be given.
