After finishing the "Pathétique" symphony, Tchaikovsky turned once again to the concerto, only to experience another wave of doubt. He confided to pianist Alexander Siloti, "As music it hasn’t come out badly—but it's pretty ungrateful." He wrote to Polish pianist and composer Zygmunt Stojowski on October 6, 1893, "As I wrote to you, my new Symphony is finished. I am now working on the scoring of my new (third) concerto for our dear Diémer. When you see him, please tell him that when I proceeded to work on it, I realized that this concerto is of depressing and threatening length. Consequently I decided to leave only part one which in itself will constitute an entire concerto. The work will only improve the more since the last two parts were not worth very much."
