The stereotyped style of cultic representations was well known as early as the Neolithic age, but the stiffly ceremonial forms of courtly art are abs… - Arnold Hauser

The fundamental difference between composing for a nobleman or a personal patron in general and working for the anonymous concert public is that the commissioned work is usually intended for a single performance, whereas the concert piece is written for as many repeats as possible. That explains not only the greater degree of care with which such a work is often composed but also the more exacting way in which the composer presents it. Now that it is possible to create works which would not be consigned to oblivion so quickly as commissioned works, he 76 sets out to create ‘immortal’ works. Haydn already composes much more cautiously and slowly than his predecessors. But even he writes over a hundred symphonies; Mozart writes only half as many and Beethoven only nine.

Rousseau’s ideas were in the air; he only expressed what many of his contemporaries knew, namely that they were faced with a choice and had to decide either for Voltairianism, with its reasonableness and respectability, or for the surrender of historical traditions and a completely new beginning. There is no personal relationship in the whole history of European culture with more profound symbolic significance than that between Voltaire and Rousseau.

... "folk art" signifies the poetical, musical, and pictorial activities of those strata of the population which are uneducated and not urbanized or industrialized. It is of the essence of this art that those who keep it in being are not only passively receptive, but normally are creative participants in the artistic activities, and yet do not stand out as individuals or claim any personal authorship of the productions. "Popular art" on the other hand is to be understood as artistic or quasi-artistic production for the demand of a half-educated public, generally urban and inclined to mass-behavior. In folk art, producers and consumers are hardly distinguished, and the boundary between them is always fluid; in the case of popular art, we find on the contrary an artistically uncreative, completely passive public, and professional production of artistic goods strictly in response to the demand for them. It is indeed a striking fact that folk art, especially folk-poetry, emerges from the ranks of those who enjoy it, whereas popular songs—the street-ballads and popular "hits"—derive from professionals belonging to and spiritually dependent upon the upper classes.
