"New Gluck Connection" by Dennis Pajot
My confidence on the science of musicology is growing as of late:
Quoting from Mr Pajot's article on "K449 Piano Concerto in Eb"
Mozart's autograph of this Concerto reads "Di Wolfgango Amadeo Mozart per la Sigre Barbara de Ployer Viena il 9 di Febro 1784". It is also the first entry in Mozart's thematic catalogue, dated again February 9, 1784. On February 20, 1784 Wolfgang wrote to his father: "The concerto [in Eb] you may have copied. Remember, do not show it to a single soul, for I composed it for Fräulein Ployer, who paid me handsomely..".
........
Now enter another interesting tidbit on the Concerto. In a recent article by Gerhard Croll in Essays in Honor of Laszlo Somfai we are informed of a theme similarity between the beginning of the 2nd movement of K449 and the beginning of the aria "Oggi Amor fra lacci miel" from Christoph Wiliblad Gluck's opera Tetide. Croll gives us the first 8 measures of both compositions and the similarity is striking. As Wolfgang Plath told Croll, "a simple coincidence is out of the question". For a detailed account the article should be read.
Gluck's "serenata" was written on the occasion of Crown Prince Joseph's first marriage and the only staged performances we know are on October 10 and 15, 1760. A concert performance is documented on February 8, 1761. Croll states it is unlikely any more performances ever took place.
How Mozart would have come across this Aria can only be speculated at. Again, a reading of Croll's article will give his "guesswork", as he admits it is. What we do know is that Mozart visited Gluck in his home in August of 1782 and March of 1783. The influence of Gluck on Mozart has been stated many times in the literature, and we know Mozart used a Gluck theme for the variations K455, as well as for the Andantino for Piano K236. The Gluck influence may be stronger than previously thought
With "Gluck" being the same man as "Grimm" (who, according to Pajot's "K006 - K009: Mozart's Op.I and Op.II Piano/Violin Sonatas", introduced the Mozarts to the Luis XV court and somehow "assisted" Wolfgang in engraving his outofnowhere first masterpieces and also wrote himself the wunderkind's greeting cards to members of the french royal family), "Rousseau", "Rossini the first", ie Gioachino Cocchi, the "provenance of Mozart's music" problem is, or rather will soon be, solved*, bearing in mind "Gluck's" other personalities and their duties pre and post his alleged 1787 death in Vienna.
*Gluck to padre Martini, 26th October 1773:
This is assuredly a bold undertaking and there will be serious obstacles, for we must face up to national prejudices against which reason is of no avail.
(Robert: Your contribution to this thread will be the more precious once you provide us with answers on Cocchi's biography, unpublished details on his London presence and the Mozarts "long -long list of contacts" while in London 1764-65.
Alternatively:
Please advise details (name of theater, actors etc) on Mysliveček's Orfeo ed Euridice performance "wieder in Italien, wo er noch einmal Mozart traf. Am 4. November 1773 leitete er die Aufführung von Orfeo ed Euridice von Christoph Willibald Gluck."-Wikipedia)
