One reason why European music has had such a strong influence throughout the world, and why it is a sophisticated achievement, is that over time the original function of the music -- whether ritual, dance, or worship -- gradually became an aspect of its style, not its defining force. Dance music could stand independent of dance, for example, and sacred music independent of religious worship, because each composition has so much internal coherence that the music ultimately depends on nothing but itself. The claims made above are compatible with each of the following EXCEPT: ['Music that is unintelligible when it is presented independently of its original function tends to be the most sophisticated music.', 'The original functions of many types of Chinese music are no longer their defining forces.', 'Some works of art lose their appeal when they are presented to serve a function other than their original one.', 'African music has had a more powerful impact on the world than European music has had.']
