There will always be those for whom some vast, ornate, and Machiavellian conspiracy theory holds far greater attraction than the pure and simple truth. They will latch on to every proof in favor of their pet theory however improbable or questionable, while rejecting every proof to the contrary as yet another element of historical falsification. Thus it is with our amateur "musicologist". The "Mozart Conspiracy" would have us believe that thousands of musicians, politicians, aristocrats, and acquaintances as well as shadowy groups such as the Freemasons, the Illuminati, the Jesuits, etc... all conspired to falsify the historical records concerning Mozart without a single voice of dissent... and to what end? To establish a Viennese or German hegemony of music... to seize musical dominance away from the Italians... in spite of the fact the J.S. Bach, Handel, Telemann, Schutz, Gluck and others had already largely achieved this goal? And the arguments in favor of this unlikely scenario? A few questionable documents. Some others misinterpreted. An argument for the artistic genius of any number of unknown composers, and an argument that it was impossible for a single, talented composer to have created so many works of unquestionable genius, but rather, that his artistic oeuvre must have been the result of the efforts of a collection of ghost writers.
Of course the artistic achievements of J.S. Bach, Handel, Haydn, Beethoven, Schubert, Brahms, Wagner, Richard Strauss and any number of other composers undermines the whole argument against the possibility that Mozart's oeuvre could have been the product of a single artistic genius. Bach alone far surpasses Mozart in the vast scale, complexity, and breadth of his artistic output to say nothing of artistic merit. Schubert easily rivals Mozart for the sheer genius of an oeuvre cut tragically short. Of course r conspiracy theorist/musicologist can always take his theory even further and argue that not only was Mozart the product of a consortium of composers, but Haydn and Beethoven as well. And Bach, Schubert, Wagner, Brahms? O, hell; let's throw them in there too. In fact the whole of Western music may be one vast conspiracy worthy of Dan Brown's fictive efforts.
But then there are the nagging questions. How did a consortium of composers create an oeuvre for Mozart that was stylistically consistent? How did they succeed in turning out a body of work for Haydn and the young Beethoven that was nearly equal in artistic merit... and yet clearly different in such a manner that any experienced musical fan can recognize Mozart's "voice" vs Haydn's? And how is it that the endless professional musicologists and music historians whose career can be "made" by the discovery of a single unknown work by Chopin or Schumann or a single unknown composer of real merit has never uncovered what surely must be the greatest career making story in the whole of musicology? How is it that these unknown composers have nothing to their own name that in any way rivals the works attributed to Mozart?
Again, our amateur "musicologist" knows that his theories challenge almost any test of credibility or logic. Our "musicologist" also knows that any true knowledgeable "musicologist" would have little difficulty in refuting any the proofs or arguments presented here. Undoubtedly, that is why he presents his arguments here and not at a musical forum where he might be rapidly challenged with the truth. I make no claims to expertise in musicology or 18th century musical history. I am experienced enough, however, with classical music to be more than doubtful about claims that the artistic output of Mozart or Haydn (etc...) are the product of a group of rather unknown and forgotten composers who never wrote anything under their own name even approaching the level of the work they offered to another. I am also experienced enough with conspiracy theorists whether we are speaking of the true identity of Homer or Shakespeare, the JFK assassination, the Illuminati, the Knights Templar, 911, etc... to take anything they have to offer at face value... especially when it goes contrary to logic, probability, and the facts as presented by those who are most certainly experts in the field.
I withdraw from any further comment. Argument with a "true believer"/conspiracy theorist is a useless endeavor. Please feel free, however, to carry on.
