[quote="Czechchris, post: 691040"]No.1 is not a theory. The Art of Fugue [B]is[/B] dots on paper! The fact that they can be interpreted to produce 'beautiful' music when played on musical instruments does not alter this. If the score (and all copies) were destroyed, and not replaced, in time the memory of it would fade and it would cease to exist. [/QUOTE] Well, we might differ here. The Art of Fugue is either dots on paper or sounds - that is the material basis for the work. But it is much more. It is the understanding of how to read a score, of counterpoint rules, of harmonic resolution, and of the need to complete a problem that was started. So the Art of Fugue exists chiefly in the brains of those that understand it: it is a mental construction that the mere dots cannot make clear.
