Pyotr Ilyich Tchaikovsky's Piano Concerto No. 3 in E-flat major, Op. posth. 75, was originally begun as a symphony in E-flat. The composer ultimately abandoned this symphony, but, in 1893, started to rework it into a piano concerto, before abandoning all but the first movement, which he completed as a concert piece for piano and orchestra. It was published posthumously, in 1894, as a single-movement Allegro Brillante. The Symphony No. 6 Pathétique was the last of Tchaikovsky's compositions to be performed in his lifetime, but the Allegro Brillante, now known as the Piano Concerto No. 3, was his last completed composition.
