Symphony No. 6 in B minor, Op. 74 Pathétique is the sixth and final completed symphony by Russian composer Pyotr Ilyich Tchaikovsky, completed and premiered in 1893. The work exemplifies late Romantic orchestral writing with expansive melodies, rich harmonies and dense orchestration, notable for its intense emotional contrasts and an unusually sombre final movement, and it occupies a pivotal place as the culmination of Tchaikovsky's symphonic output and a significant example in the late Romantic repertoire.
