)" Schonberg also complained that the Mozart symphony had " no force, no charm, no inflection, with a metronomic rigidity.

" Six months later, Mozart complained that it was taking a long time to secure enough subscribers.

It is one of the most enigmatic pieces of music ever composed, mostly because of the myths and controversies surrounding it, especially around how much of the piece was completed by Mozart before his death.

The biographer Alexander Wheelock Thayer believes that Mozart's rivalry with Salieri could have originated with an incident in 1781 when Mozart applied to be the music teacher of Princess Elisabeth of Württemberg, and Salieri was selected instead because of his reputation as a singing teacher.

In his last surviving letter from 14 October 1791, Mozart tells his wife that he collected Salieri and Caterina Cavalieri in his carriage and drove them both to the opera ; about Salieri's attendance at his opera The Magic Flute, speaking enthusiastically: " He heard and saw with all his attention, and from the overture to the last choir there was not a piece that didn't elicit a ' Bravo!

In an 1839 letter, Franz Liszt described his playing as " charming ", and planned to play through all the Mozart and Beethoven violin sonatas with Ingres.

However, most of Clementi's sonatas are more difficult to play than those of Mozart, who wrote in a letter to his sister that he would prefer her not to play Clementi's sonatas due to their jumped runs, and wide stretches and chords, which he thought might ruin the natural lightness of her hand.

Years later, in 1778, Mozart visited Gossec during a trip to Paris, and described him in a letter to his father as " a very good friend and a very dry man ".

In a letter to his father Leopold written from Munich on 11 October 1777, Mozart described his character as " full of fire, spirit and life.

According to the same letter of Wolfgang Mozart written from Munich on 11 October 1777, an incompetent surgeon burned off Mysliveček's nose while trying to treat a mysterious illness.

A letter of Leopold Mozart to his son of 1 October 1777, refers to the illness as something shameful for which Mysliveček was deserving of social ostracism.

In the entire Mozart correspondence, no individual outside the Mozart family was ever the cause for so much outpouring of emotion as what is found in Wolfgang's letter of 11 October 1777.

In a letter written by Wolfgang Amadeus Mozart to his father from Munich on 11 October 11, 1777, it is mentioned that Mysliveček bragged of his influence with the management of the Teatro San Carlo in Naples, the most prestigious venue for the performance of Italian serious opera in Europe: he apparently had the power to recommend the engagement of singers who were to be featured in productions planned for the 1778 – 79 operatic season there.

We first learn of Süssmayr from Mozart in a letter dated 7 June 1791, although the text would indicate that both people knew one another for some time previous.

Perhaps in the spirit of even truer " affection ," one can imagine Mozart writing this excerpt from a letter to Constanze: " Please give a few good kicks in my name.

It should be noted that in one letter to Constanze, Mozart notes, " I hope that Süssmayr will not forget what I laid out for him …" Rearrangements, perhaps?

Süssmayr wrote the publisher Breitkopf & Härtel a letter on 8 February 1800 detailing his claims as to what he had completed, and what Mozart had composed.

( Interestingly, Süssmayr claimed in a letter that his stage farce “ Der rauschige Hans ,” composed in 1791, “… had been composed under the supervision of the late, immortal Mozart .” True or not, it IS a claim for collaboration of sorts, as I doubt Mozart would have merely offered verbal help.

In a letter to his father Leopold dated 14 January 1783, Mozart alluded to a vow he had made " in the depth of his heart " to write a work of thanksgiving for his wife Constanze, who sang the " Et incarnatus est " at its premiere.

" Amadeus " may have originated as a facetious name ; Mozart never used the name except in jest, when he signed himself in mock Latin in three letters as " Wolfgangus Amadeus Mozartus "; this was certainly no accident as in one letter he did the same to the date of the letter as well: adding "- us " to the end of each word.

In a letter dated 26 September 1781, Mozart wrote, " Let me now turn to Belmonte's aria in A major, ‘ O wie ängstlich, o wie feurig ’.

Despite Mozart's father Leopold's great opinion of Eberlin, and having sent the young Mozart some of Eberlin's best known works, his keyboard pieces, the young Mozart later tired of them, writing in a letter of April 20, 1782 that Eberlin's works were " far too trivial to deserve a place beside Handel and Bach.

These famous composers were also among Hoffmeister's personal friends: Mozart dedicated his String Quartet in D ( K. 499 ) to him, and Beethoven addressed him in a letter as " most beloved brother ".

Mozart himself praised the orchestra on numerous occasions, here in a letter written to his father:

After his early piano lessons with Otto Cossel, Brahms studied piano with Eduard Marxsen, who had studied in Vienna with Ignaz von Seyfried ( a pupil of Mozart ) and Carl Maria von Bocklet ( a close friend of Schubert ).

Mozart was a close friend of one of the singer-composers of the troupe, tenor Benedikt Schack ( the first Tamino ), and had contributed to the compositions of the troupe, which were often collaboratively written.

Mozart also made a strong impression on the manager of the theater, Count Franz Xaver Rosenberg-Orsini, when in the home of Mozart's friend and patroness Maria Wilhelmine Thun the Count heard him play excerpts from his opera Idomeneo, premiered with great success the previous year in Munich.

An old school friend told Wolfgang Amadeus Mozart in 1777, " Ah he was a great fellow.

The basset clarinet was most notably associated with the clarinet virtuoso Anton Stadler ( 1753-1812 ), a contemporary and good friend of Mozart.

Mysliveček provided his younger friend Wolfgang Amadeus Mozart with significant compositional models in the genres of symphony, Italian serious opera, and violin concerto ; both Wolfgang and his father Leopold Mozart considered him an intimate friend from the time of their first meetings in Bologna in 1770 until he betrayed their trust over the promise of an operatic commission for Wolfgang to be arranged with the management of the Teatro San Carlo in Naples.

Calling him a " dumb boob ," " ox ," and " court jester " may seem a bit strong for the " classic " Mozart, but he used these same sorts of terms for Constanze, Nannerl, his cousin the Basle, and his friend the horn player Leutgeb.

Sigismund Neukomm wrote that he was " not so much a friend as a very self-opinionated patron of Haydn and Mozart.

* Mozart's only official mention as " Wolfgang Amadeus " in an official document made during his lifetime was found in 1998 by Mozart scholar Michael Lorenz in the registers of the Lower Austrian Governorship, where in May 1787 " Mozart Wolfgang Amadeus " is referred to as having applied for the return of his written surety for his friend Franz Jakob Freystädtler.
