Despite his stated intentions, Tchaikovsky had written "End of movement 1" on the last page of the "Allegro brillante" that would be published by P. Jurgenson as the Third Piano Concerto. At the insistence of the composer's brother Modest, Taneyev began to study the unfinished sketches of the allegro and finale from the E-flat symphony in November 1894. Tchaikovsky had begun to arrange these movements for piano and orchestra but they remained in sketch form. Both Taneyev and Modest questioned how they should be published—as two orchestral movements for a symphony or as a piece for piano and orchestra. After a letter from pianist Alexander Siloti to Modest in April 1895, he and Taneyev took the piano-and-orchestra route. The first performance took place on February 8, 1897 in St. Petersburg with Taneyev as soloist.
