These evening concerts in the theatre are called here "musical academies." As I claimed no honorarium, Count Gallenberg hastened on my appearance.
In a letter to Titus Woyciechowski, dated September 12, 1829, he says:-- The sight of the Viennese public did not at all excite me, and I sat down, pale as I was, at a wonderful instrument of Graff's, at the time perhaps the best in Vienna.

Beside me I had a painted young man, who turned the leaves for me in the Variations, and who prided himself on having rendered the same service to Moscheles, Hummel, and Herz.

Believe me when I say that I played in a desperate mood; nevertheless, the Variations produced so much effect that I was called back several times.Mdlle.Veltheim sang very beautifully.

Of my improvisation I know only that it was followed by stormy applause and many recalls.
To the cause of the paleness and the desperate mood I shall advert anon.
Chopin was satisfied, nay, delighted with his success; he had a friendly greeting of "Bravo!" on entering, and this "pleasant word" the audience repeated after each Variation so impetuously that he could not hear the tuttis of the orchestra.

At the end of the piece he was called back twice.
