“In spring the students were generally set an important task to be completed during the summer holidays. In the summer of 1864 Tchaikovsky was expected to write a long overture on the subject of Ostrovsky’s[7] drama, _The Storm_. This work he scored for the most ‘heretical’ orchestra: tuba, English horn, harp, tremolo for violins _divisi_, etc. When the work was finished he sent it to me by post, with the request that I would take it to Rubinstein (I cannot remember why he could not attend in person). I carried out his wish, and Rubinstein told me to return in a few days to hear his opinion. Never in the course of my life have I had to listen to such a homily on my own sins as I then endured vicariously (it was Sunday morning too!). With unconscious humour, Rubinstein asked: ‘How dared you bring me such a specimen of your own composition,’ and proceeded to pour such vials of wrath upon my head that apparently he had nothing left for the real culprit, for when Peter Ilich himself appeared a few days later, the Director received him amiably, and only made a few remarks upon the overture....
“One of Rubinstein’s most urgent desires was the organisation of a school orchestra. In the early days of the Conservatoire, however, there was no immediate hope of realising this wish. Apart from the numerous violinists, attracted by the name of Wieniawsky, there were few, during the first year, who could play any other orchestral instrument even tolerably well. Rubinstein, who at that time had no great income, spent at least 1,500 roubles in the gratuitous tuition of those instruments he needed for his orchestra. There was an immediate response among those who were enterprising. Tchaikovsky expressed a wish to learn the flute. He studied for two years, and became a satisfactory second flute in this orchestra. On one occasion he took part in a flute quartet of Kuhlau’s at a musical evening in honour of Madame Clara Schumann’s visit to Petersburg. Afterwards, finding no special use for this accomplishment, he gave it up entirely.
“Of even less importance were the organ lessons he took for a time from the famous Heinrich Stiehl. The majestic tone of this instrument, heard in the mystic twilight of the empty Lutheran church in Petersburg, made a profound impression upon Tchaikovsky’s poetic temperament. But the impression was fleeting; his imagination was attracted in other directions, and he grew more and more remote from the works of Bach. He never composed a single piece for this instrument.”
