Mapping of derivations by synthetic variables in Peça para dois minutos by Guerra-Peixe

Abstract

“Two-Minute Piece”, by Guerra-Peixe, serial work for solo piano, is the object of study in this current analysis. Recurring motifs were observed, in such way that prompted the curiosity to discover the techniques for recurring ideas, development and structuring. A conclusion came that the work has got a small omnipresent motif, and it also gets rid of the more rigid structure of dodecaphonism. The methods used were the motivic analysis by Schoenberg, the traditional analysis of variations, part of the technique of “synthetic variables” (developed by one of the authors), and a restricted part of the Set-Theory.
