Mussorgsky in the context of "Maurice Ravel"

Orchestration is the study or practice of writing music for an orchestra (or, more loosely, for any musical ensemble, such as a concert band) or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orchestration is the assignment of different instruments to play the different parts (e.g., melody, bassline, etc.) of a musical work. For example, a work for solo piano could be adapted and orchestrated so that an orchestra could perform the piece, or a concert band piece could be orchestrated for a symphony orchestra.

In classical music, composers have historically orchestrated their own music. Only gradually over the course of music history did orchestration come to be regarded as a separate compositional art and profession in itself. In modern classical music, composers almost invariably orchestrate their own work. Two notable exceptions to this are Ravel's orchestration of Mussorgsky's solo piano work Pictures at an Exhibition and Malcolm Arnold's orchestration of William Walton's String Quartet in A minor, producing the latter's Sonata for Strings.

Joseph Maurice Ravel (7 March 1875 – 28 December 1937) was a French composer, pianist and conductor. He is often associated with Impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.

Born to a music-loving family, Ravel attended France's premier music college, the Paris Conservatoire; he was not well regarded by its conservative establishment, whose biased treatment of him caused a scandal. After leaving the conservatoire, Ravel found his own way as a composer, developing a style of great clarity and incorporating elements of modernism, baroque, neoclassicism and, in his later works, jazz. He liked to experiment with musical form, as in his best-known work, Boléro (1928), in which repetition takes the place of development. Renowned for his abilities in orchestration, Ravel made some orchestral arrangements of other composers' piano music, of which his 1922 version of Mussorgsky's Pictures at an Exhibition is the best known.

The Mariinsky Theatre (Russian: Мариинский театр, romanized: Mariinskiy teatr, also transcribed as Maryinsky or Mariyinsky) is a historic opera house in Saint Petersburg, Russia. Opened in 1860, it became the preeminent music theatre of late 19th-century Russia, where many of the stage masterpieces of Tchaikovsky, Mussorgsky, and Rimsky-Korsakov received their premieres. Through most of the Soviet era, it was known as the Kirov Theatre. Today, the Mariinsky Theatre is home to the Mariinsky Ballet, Mariinsky Opera and Mariinsky Orchestra. Since Yuri Temirkanov's retirement in 1988, the conductor Valery Gergiev has served as the theatre's general director.
