In the last five years the electro-acoustic genre has proven to be more than a tool, to be a medium of expression for composers and listeners as well. For the porpoise of better understanding this changing of view on the musical community of today, a look at few points on the view of the history of music in Latin American Countries, would not be insufficient. In contrast with Latin America music, European music is logic, Its history is part of a series of continuous development and research in all of its technique, and aesthetics. The differences in musical thought can be seen in the trade mark or better originality on its works. Each geographical location has been devoted to a particular genre, and has succeeded among the history of western music.There has been a logical sequence of techniques, that have been applied to European instrument design and compositions to be played on such instruments. There is organized thought in most music schools and conservatories. Research is continuous and methodical. The consequences of all this planned organization are a series of coherent and clear facts that appeal to the ears of educated audiences as well as players and composers worldwide. Innovation of European thought depends upon the need to better communicate a musical feature based on the spirit of an age. This means that musical enlightenment is gradual and a function of an exchange of ideas between composers and theoreticians. This, allows for showing and proving new concepts as well as those of a heritage of classical music compositions of western music through the lives of its creators. The spirit of the European musicians depends on the future of their tradition.
Latin American Music instead, is not a function of its own values and cultural facts. This exists as various emotional impulses ranging from mind maturity or growing, mind states, cultural and racial mixtures, and trans-cultural values. As a result, a phenomenon like this, leaves the musicologists with almost no method to apply western thought to analyze questions on music of the central and southern parts of the American continent. In comparing the works of an outstanding European composer like Arnold Schoenberg with those of a great South American Composer, Heitor Villa-Lobos, we see that, while the works of the second composer are part of a surprise and spontaneous phenomenon, the works of Schoenberg are part of a family of intellectual, and musical heritage. The compositions of Villa-Lobos are consequence of discontinuous struggle to adapt western music techniques to his compositions and work style. atonality is part of a historical development in music taking place in central Europe. The compositions of the Brazilian composer are an amalgam of the most advanced methods used in all the countries of the old continent.
