Once having played at Versailles, they were sure of access to the most distinguished society.[20022]A small oil painting, now in the Museum at Versailles, shows little Wolfgang at the clavier in the _salon_ of Prince Conti, the centre of an assemblage of great people. Finally, having established their (36) {EARLY JOURNEYS.} position in private society they gave two great concerts (on March 10 and April 9, 1764) in the rooms of a certain fashionable M. Felix, who had built a little theatre for private representations. The permission to give these concerts was a favour obtained with difficulty, as they infringed the privileges both of the Concert Spirituel and of the French and Italian theatres. The result was in every respect a brilliant success. Marianne Mozart played the most difficult compositions of the musicians then living in Paris, especially of Schobert and Eckart, with a precision and correctness that could not have been surpassed by the masters themselves. Schobert was a native of Strasburg, cembalist to the Prince de Conti; as a composer he was famous for his grace and fire, especially in allegros,[20023] but as a man he was not all he should have been, according to L. Mozart. He was a false flatterer, his religion was _à la mode_, and his envy was often so ill-concealed as to excite ridicule. Eckart, on the contrary, was a worthy man, and quite free from jealousy; he had come from Augsburg to Paris in 1758, and was highly esteemed as a clavier-player and teacher. Wolfgang's performances on the clavier, organ, and violin, extraordinary as they were, were thrown into the shade by the proofs he gave of almost incredible musical genius.[20024] He not only accompanied at sight Italian and French airs, but he transposed them [prima vista]. At that time, accompanying meant more than the playing of prepared passages for the piano or clavier; it involved the choice at the moment of a fitting accompaniment for the {FIRST PRINTED COMPOSITIONS.} (37) several parts of the score, or the supplying of harmonies to the bass.
