Unlike other historical periods, the Twentieth Century can not be summarized in a single musical style.
The precursors of this change in musical creation are the Impressionists and Symbolists, the new nationalism, expressionism and the historical vanguards.
Two currents emerged in the first half of the century: neoclassicism and twelve-tone serial. Shortly thereafter, in the fifties, the integral serialism creates series for heights, dynamics, rhythms and timbres. This complex music is confronted in the sixties for the aleatoric music, minimalism and Happening.
Schoenberg was the creator of the Twelve-tone Serial Music. Pitch were no longer the main problem turning the composer's attention to new richest in terms of timbres and dynamic compositions.
Not everything that is made in the twentieth century music for traditional instruments. The appearance of the tape makes some composers work with the cropping and gluing ribbons, giving rise to Concrete Music.
Other instruments that did not exist in the previous century become worked by composers of electronic music and so arises.
It is hard to know which direction is going to take the Music of the 21st Century.
The line between Popular Classical Music increasingly blurs.
New timbres and instruments arise every day and with Internet and new technologies of image and sound is impossible to think which way is going to take Music creation.
In addition, the way of thinking of the audiences and the artist are changing in all the arts, changing as well the rules of the game. Only an educated and innovative society would be able to find the best formulas. If the official culture and taste of young people continues to be so conservative little or nothing could be expected, but if something changes that tendency, the more than possible manifestations of the Music of the Future will be of great quality and creativity.
