Piano Concerto No. 3 (Tchaikovsky)
Pyotr Ilyich Tchaikovsky's Piano Concerto No. 3 in E♭ major was at first conceived by him as a symphony in the same key. But he abandoned that idea, jettisoned all but the planned first movement, and reworked this in 1893 as a one-movement Allegro brillante for piano and orchestra. His last completed work, it was duly published as Opus 75 the next year, after he died, but given by publisher Jurgenson the title "Concerto No. 3 pour Piano avec accompagnement d'Orchestre".
