Tchaikovsky has told so well the tale of Rubinstein’s injury to his self-esteem in one of his subsequent letters to Frau von Meck, that I think it advisable to publish the entire letter in this particular chapter of the book. _To N. F. von Meck._ “SAN REMO, _January_ 21_st_ (_February_ 2_nd_), 1878. “ ... In December, 1874, I had written a pianoforte concerto. As I am not a pianist, it was necessary to consult some virtuoso as to what might be ineffective, impracticable, and ungrateful in my technique. I needed a severe, but at the same time friendly, critic to point out in my work these external blemishes only. Without going into details, I must mention the fact that some inward voice warned me against the choice of Nicholas Rubinstein as a judge of the technical side of my composition. However, as he was not only the best pianist in Moscow, but also a first-rate all-round musician, and, knowing that he would be deeply offended if he heard I had taken my concerto to anyone else, I decided to ask him to hear the work and give me his opinion upon the solo parts. It was on Christmas Eve, 1874. We were invited to Albrecht’s house, and, before we went, Nicholas Rubinstein proposed I should meet him in one of the class-rooms at the Conservatoire to go through the concerto. I arrived with my manuscript, and Rubinstein and Hubert soon appeared. The latter is a very worthy, clever man, but without the least self-assertion. Moreover, he is exceedingly garrulous, and needs a string of words to say ‘yes’ or ‘no.’ He is incapable of giving his opinion in any decisive form, and generally lets himself be pulled over to the strongest side. I must add, however, that this is not from cowardice, but merely from lack of character. “I played the first movement. Never a word, never a single remark. Do you know the awkward and ridiculous sensation of putting before a friend a meal which you have cooked yourself, which he eats--and holds his tongue? Oh, for a single word, for friendly abuse, for _anything_ to break the silence! For God’s sake say _something_! But Rubinstein never opened his lips. He was preparing his thunderbolt, and Hubert was waiting to see which way the wind would blow. I did not require a judgment of my work from the artistic side; simply from the technical point of view. Rubinstein’s silence was eloquent. ‘My dear friend,’ he seemed to be saying to himself, ‘how can I speak of the details, when the work itself goes entirely against the grain?” I gathered patience, and played the concerto straight through to the end. Still silence.
