THE SPREAD OF ALEATORISM AS A COMPOSITION TECHNIQUE IN WESTERN MUSIC

Abstract

The research focuses on a problem of the music of the second half of the 20th century, more precisely within the aleatoric current that developed in the 6-8 decades. This trend promoted, in addition to multiple compositional innovations, the principle of improvisation by which the performer(s) gets involved in the act of composition. The existence of an important variety of typologies and concepts under which improvisation has been used as a creative principle can become disconcerting for a performer eager to enter this world in which he will be forced to assume the role of performer and co-creator.
