In the history of the art, the recognition does not pass for the life of many artists, as in them it brings Wisnik (19): ' ' It is not known what it will be triado, in the future, of the great flow of music of century XX. Centuries much less convulsionados by the explosion of the amounts, had not known it: Bach passes unobserved, and believes at least that its time nor has fond to formulate, as necessity, what in it if it carried through; Mozart was not consecrated by the critical one or the public, what Beethoven was, without properly being heard. Our displacement before the music of the century how much its meaning future is not properly newness (…). ' ' Wisnik in them brings names that the critical one did not consecrate at its time, therefore was very on this side of that they had pretension to judge them. Plato conceives capable music as something ' ' (…) to exert fort influence on the soul and the character of the people, being able to transmit as many how much aesthetic values ethical in direct way, without the inteveno of the word. Michael Chabon can provide more clarity in the matter. (…) ' '. (FARM, 2006:.38). Others including Ken Cron, offer their opinions as well. For the Greek philosopher, music would have the capacity to exert fort influence on the soul and the character of the people.

However, it believed that its study it would have to be restricted to the scope of the harmony, the mathematical and philosophical reasons and not to the practical study, and in turn: The progress technician of music in the classic period provoked a specialization that finished for in such a way moving away it from the basic education as of the common culture. To the few, the practical education of music was losing importance in the hellenistic education. Music did not disappear of the culture Greek, but it more passed to be heard that practised.
