The undulatory analysis and musical composition

The undulatory analysis method can be a useful tool for music composition. In the following example, the undulatory trajectory (see previous video) of A. Schoenberg's Piece II from the six pieces for piano opus 19 is used as a model for conducting an electronic part based computer generated sounds. The model-video presented below, displays real-time, each of the points of the wave trajectoria of the piece of Schönberg simultaneously with those generated by the trajectoria of the electronics module, called Cenon.

It can be checked in real time, as the workpiece passes, and the shape of both parts are equal. Here we demonstrate how -from any form, in this case the shape of the piano piece II of Schönberg- can build a new work.

It is important to remember that only the undulatory trajectory - the form - of the piano piece has been used. The other structures of the piano piece, durations structure, dynamics, etc. are not used in this new piece of music.

Communication ( "paper") on this subject was presented by the author in 2016 in the
First Conference on Computer Simulation of musical creativity at the University of Hudderfield in England.
