Modest Petrovich Mussorgsky

Modest Petrovich Mussorgsky (Russian: Модест Петрович Мусоргский, romanized: Modest Petrovich Musorgsky; IPA: [mɐˈdɛst pʲɪˈtrovʲɪtɕ ˈmusərkskʲɪj] ; 21 March [O.S. 9 March] 1839 – 28 March [O.S. 16 March] 1881) was a Russian composer, one of the group known as "The Five." He was an innovator of Russian music in the Romantic period and strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music.

Many of Mussorgsky's works were inspired by Russian history, Russian folklore, and other national themes. Such works include the opera Boris Godunov, the orchestral tone poem Night on Bald Mountain and the piano suite Pictures at an Exhibition.

For many years, Mussorgsky's works were mainly known in versions revised or completed by other composers. Many of his most important compositions have posthumously come into their own in their original forms, and some of the original scores are now also available.

At the State Institute for Art Studies in Moscow, M. P. Musorgsky's Complete Works: Academic Edition is being published. As of 2026, six volumes have been issued, including the opera Boris Godunov: two volumes of the vocal score (2020) and four volumes of the full score (2025). The vocal score was prepared by Nadezhda Teterina and Evgeny Levashev. The full score was prepared by Evgeny Levashev, Nadezhda Teterina, and Roman Berchenko.
