This paper integrates a broad research on musical variation. It specifically addresses an original concept, namely "evolutionary variation" (EV), resulted from an association between Schoenbergian principles of Grundgestalt and developing variation and some ideas from Genetics and Evolutionary Biology. The application of this concept in a compositional system (Gr-S) aims at the production of a large number of variants from a basic musical idea, covering a wide spectrum of similarity relationships. An application of EV in the composition of CTG, for woodwind trio, is described in the second part of the paper.
