“As their ties to social, political, and religious institutions loosened, they could increasingly fashion their work solely according to the dictates of their own consciences. Beholden to no higher authority than their creative imagination, the progressive composer could experiment at will, following the inclination of the age to pursue the unique and unusual at the expense of the conventional and accepted. This new artistic freedom went hand in hand with the period's overall esthetic orientation, for the music was able to follow an independent course, without concern for the comprehension and receptivity of a broadly based public, the more it was able to serve as a vehicle for personal expression and to assume it's new role as a symbol of individuality or, eventually, of open revolt.”
