Tchaikovsky Symphony no. 6 in Bm "Pathetique", Op. 74, is his final completed symphony, written in 1893. He premiered it nine days before his death, and made some corrections, thus creating the version we know today. It was the last of Tchaikovsky's compositions premiered in his lifetime; his last composition of all, the single-movement 3rd Piano Concerto, Op. 75, which was completed in October 1893, a short time before his death, received a posthumous premiere.
