Pictures at an Exhibition is a piano suite in ten movements, plus a recurring and varied Promenade theme, written in 1874, by Russian composer Modest Mussorgsky. It is a musical depiction of a tour of an exhibition of works by architect and painter Viktor Hartmann put on at the Imperial Academy of Arts in Saint Petersburg, following his sudden death in the previous year. Each movement of the suite is based on an individual work, some of which are lost. The composition has become a showpiece for virtuoso pianists, and became widely known from orchestrations and arrangements produced by other composers and contemporary musicians, with Maurice Ravel's 1922 adaptation for orchestra being the most recorded and performed. The suite, particularly the final movement, "The Bogatyr Gates", is widely considered one of Mussorgsky's greatest works.

Salammbô (Russian: Саламбо, Salambo) [alternative title: The Libyan (Russian: Ливиец, Liviyets)] is an unfinished opera in four acts by Modest Mussorgsky. The fragmentary Russian language libretto was written by the composer, and is based on the novel Salammbô (1862) by Gustave Flaubert, but includes verses taken from poems by Vasiliy Zhukovsky, Apollon Maykov, Aleksandr Polezhayev, and other Russian poets. Salammbô was Mussorgsky's first major attempt at an opera. He worked on the project from 1863 to 1866, completing six numbers before losing interest. In 1865 Mussorgsky's mother died and he felt the loss deeply. There are sources indicating Mussorgsky composed more but did not write down some further scenes, in particular a love scene featuring Mathô and Salammbô. A 1872 drawn-up catalogue mentions a Salammbô scene, unlike the presently known material, completed in 1865.

The following is a list of compositions by Russian composer, Modest Mussorgsky.

Night on Bald Mountain (Russian: Ночь на лысой горе, romanized: Noch′ na lysoy gore), also known as Night on the Bare Mountain, is a series of compositions by Modest Mussorgsky (1839–1881). Inspired by Russian literary works and legend, Mussorgsky composed a "musical picture", St. John's Eve on Bald Mountain (Russian: Иванова ночь на лысой горе, romanized: Ivanova noch′ na lysoy gore) on the theme of a Witches' Sabbath occurring at Bald Mountain on St. John's Eve, which he completed on that very night, 23 June 1867. Together with Nikolai Rimsky-Korsakov's Sadko (1867), it is one of the first tone poems by a Russian composer. Although Mussorgsky was proud of his youthful effort, his mentor, Mily Balakirev, refused to perform it. To salvage what he considered worthy material, Mussorgsky attempted to insert his Bald Mountain music, recast for vocal soloists, chorus, and orchestra, into two subsequent projects—the collaborative opera-ballet Mlada (1872), and the opera The Fair at Sorochyntsi (1880). However, Night on Bald Mountain was never performed in any form during Mussorgsky's lifetime. In 1886, five years after Mussorgsky's death, Rimsky-Korsakov published an arrangement of the work, described as a "fantasy for orchestra." Some musical scholars consider this version to be an original composition of Rimsky-Korsakov, albeit one based on Mussorgsky's last version of the music, for The Fair at Sorochyntsi: I need hardly remind the reader that the orchestral piece universally known as 'Mussorgsky's Night on the Bare Mountain' is an orchestral composition by Rimsky-Korsakov based on the later version of the Bare Mountain music which Mussorgsky prepared for Sorochintsy Fair. It is through Rimsky-Korsakov's version that Night on Bald Mountain achieved lasting fame. Premiering in Saint Petersburg in 1886, the work became a concert favourite. Half a century later, the work obtained perhaps its greatest exposure through the Walt Disney animated film Fantasia (1940), featuring an arrangement by Leopold Stokowski, based on Rimsky-Korsakov's version. Mussorgsky's tone poem was not published in its original form until 1968. It has started to gain exposure and become familiar to modern audiences.
