Classical music
There is no single definition of classical music. It can be understood as the music of the past that survived during the centuries and has acquired broad audience in the present society. In this sense of the word anything can be classical if it was created in the past and is still popular and widely used (like clothing, traditions, genres of movies, plays, all kinds of shows etc.). Thus today not only the greatest works of the musical art but also the most successful examples of the entertainment genres of the past may be considered classical. Among them are the greatest works of the French, Viennese and Hungarian operetta of the nineteenth – beginning of the twentieth centuries, waltzes by Johann Strauss etc. From the historical point of view classical music is the music of XVIII—beginning of the XIX (this period is traditionally connected with classicism). Nevertheless, the concept of classicism is not very applicable to music. From the typological point of view classical music is the so called academic music, which continues the musical traditions, forms and genres that were created in Europe in the XVII—XIX centuries (like opera, symphony, sonata etc). In this meaning classical music is always in a certain state of conflict with almost all types of modern music – from pop to jazz, although some attempts have been made in the twentieth century to unite academic music with other traditions and styles, for example symphonic accompaniment that's now widely used by many rock bands (like Deep Purple or Metallica).
