Manfred is a "Symphony in Four Scenes" in B minor by Pyotr Ilyich Tchaikovsky, his Opus 58, but unnumbered. It was written between May and September 1885 to a program based upon the 1817 poem of the same name by Byron, coming after the composer's Fourth Symphony and before his Fifth.

The Symphony No. 6 in B minor, Op. 74, also known as the Pathétique Symphony, is Pyotr Ilyich Tchaikovsky's final completed symphony, written between February and the end of August 1893. The composer entitled the work "The Passionate Symphony", employing a Russian word, Патетическая (Pateticheskaya), meaning "passionate" or "emotional", which was then translated into French as pathétique, meaning "solemn" or "emotive".
