Dialectics of use by Composers of Natural and Electronic Sounds in European Composition of the 2nd Half of the 20th Century

Abstract

This paper aims at identifying the main trends in musical composition using Electronic sounds along with Acoustic sounds, through the Analysis of the nature and relationship between those two types of sounds in the framework of
European composers of the second half of the twentieth century. 
The study reveals three major tendencies in the relationship between Acoustic and Electronic sounds. The direct contrast between these two sets, is the first form of this dialectic relationship.
The second tendency is represented in the activation of additional elements of musical composition, which in turn, constitute alternative criteria to divide the voices used and new lines of contrast between them, in an attempt to avoid the single direct contrast in musical composition. 
The third dimension represents a return to the cultural symbolism of the "Acoustic” and “Electronic" and establishing a complementary relation between them
