Modest Petrovich Mussorgsky (1839 – 1881) was a Russian composer, one of the group known as "The Five". He was an innovator of Russian music in the romantic period. He strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music. Many of his 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.

While not utterly incomprehensible, the task of explaining the compositional history of Khovanshchina is blessedly beyond the scope of this article. Left unfinished at his death as a mass of disorderly manuscripts, Khovanshchina resists comprehension either as a drama, an opera or even a piece of music. It also resisted successful completion: after Mussorgsky's death in 1882, his friend Rimsky-Korsakov tried to put his manuscripts in order and to create a performing edition of Khovanshchina. Part of this task, the least part of this impossible task, was the opera's orchestration, including its prelude, called Dawn on the Muscovy River.

The curtain rises during the prelude to reveal the pre-dawn city of Moscow at the end of the seventeenth century, the period which marks the rise of Peter the Great. Mussorgsky had left only indications as to how the scoring was to be handled, and Rimsky understandably chose to orchestrate it in his own manner. One might not think that this would make an enormous difference in the essence of the music. But, to a surprising extent, Dawn on the Muscovy River is orchestral in its essence, and Rimsky's orchestration, with its bright woodwinds and light basses, with its tempo rubato and its languorous tempo, makes the work seem more like a pastoral than a city scene, more like a light elegy than the prelude to a historical tragedy which would end with the deaths of many of the characters and the mass self-immolation of most of the rest.

Although Rimsky did succeed in creating a performing edition of the Khovanshchina and of the prelude, much of Mussorgsky's essence was lost in the recomposition.
