New tendencies in harmony in the 20 and 21 century
Analytical rationalization and codification of new harmonic tendencies are amongst the prerogatives of musical theory. Studying contemporary acoustic and sonic organization as a phenomenon which perpetually enlarges and reinvents its very own substance requires for the pre-defined theoretical conceptions of earlier times regarding the phenomenon of harmony and its integration into the contemporary realms of art of to be corrected by finding new and more adequate instruments of knowledge.
This presentation observes the transformation into the harmonic system of the 20 and 21 century, which is expressed by the effect of new harmonic conformities such as chromatization, dissonance emancipation, linearization and polyphonization, as well as the individualized harmony as part of the common tendency of individualizing musical language. It outlines the basic tendencies in harmony which have been stimulated by the arrival of new tonal organizational systems (neotonality and neomodality, free atonal and serial dodecaphonic principles, sonoricism and aleatoricism) in the discourse of vanguard schools from the beginning and middle of the last century and the post-modern epoch that followed.
The research of new and somewhat dissimilar phenomena and tendencies in harmony during the 20 and 21 centuries represents an objective premise to a more profound acquaintance with the peculiarities of contemporary musical thought and the complex art processes which have been evolving in the art of music during the past and present centuries.
