A string orchestra is an orchestra consisting solely of a string section made up of the bowed strings used in Western Classical music. The instruments of such an orchestra are most often the following: the violin, which is divided into first and second violin players (each usually playing different parts), the viola, the cello, and usually, but not always, the double bass. String orchestras can be of chamber orchestra size ranging from between 12 (4 first violins, 3 second violins, 2 violas, 2 cellos and 1 bass = 12) and 21 musicians (6 first violins, 5 second violins, 4 violas, 4 cellos and 2 double basses= 21) sometimes performing without a conductor. It could also consist of the entire string section of a large symphony orchestra which could have 60 musicians (16 first violins, 14 second violins, 12 violas, 10 cellos and 8 double basses = 60; Gurre-Lieder calls for 84: 20.20.16.16.12).

Fantaisie for piano and orchestra (L.73/CD.72), is a composition for piano and orchestra by French composer Claude Debussy. It was composed between October 1889 and April 1890, but only received its first public performance in 1919, a year after Debussy's death. The work is dedicated to the pianist René Chansarel, who had been scheduled to play the solo part for the cancelled premiere in 1890.

Images pour orchestre, L. 122, is an orchestral composition in three sections by Claude Debussy, written between 1905 and 1912. Debussy had originally intended this set of Images as a two-piano sequel to the first set of Images for solo piano, as described in a letter to his publisher Durand as of September 1905. However, by March 1906, in another letter to Durand, he had begun to think of arranging the work for orchestra rather than two pianos.

La mer, trois esquisses symphoniques pour orchestre (French for The sea, three symphonic sketches for orchestra), or simply La mer (The Sea), L. 109, CD. 111, is an orchestral composition by the French composer Claude Debussy. Composed between 1903 and 1905, the piece premiered in Paris in October 1905. It was initially not well-received; even some who had been strong supporters of Debussy's work were unenthusiastic, even though La mer presented three key aspects of Debussy's aesthetic: Impressionism, Symbolism and Japonism. The work was performed in the US in 1907 and Britain in 1908; after its second performance in Paris in 1908, it quickly became one of Debussy's most admired and frequently performed orchestral works. The first audio recording of the work was made in 1928. Since then, orchestras and conductors from around the world have set it down in many studio or live concert recordings.

Achille Claude Debussy (French pronunciation: [aʃil klod dəbysi]; 22 August 1862 – 25 March 1918) was a French composer. He is sometimes seen as the first Impressionist composer, although he vigorously rejected the term. He was among the most influential composers of the late 19th and early 20th centuries. Born to a family of modest means and little cultural involvement, Debussy showed enough musical talent to be admitted at the age of ten to France's leading music college, the Conservatoire de Paris. He originally studied the piano, but found his vocation in innovative composition, despite the disapproval of the Conservatoire's conservative professors. He took many years to develop his mature style, and was nearly 40 when he achieved international fame in 1902 with the only opera he completed, Pelléas et Mélisande. Debussy's orchestral works include Prélude à l'après-midi d'un faune (1894), Nocturnes (1897–1899) and Images (1905–1912). His music was to a considerable extent a reaction against Wagner and the German musical tradition. He regarded the classical symphony as obsolete and sought an alternative in his "symphonic sketches", La mer (1903–1905). His piano works include sets of 24 Préludes and 12 Études. Throughout his career he wrote mélodies based on a wide variety of poetry, including his own. He was greatly influenced by the Symbolist poetic movement of the later 19th century. A small number of works, including the early La Damoiselle élue and the late Le Martyre de saint Sébastien have important parts for chorus. In his final years, he focused on chamber music, completing three of six planned sonatas for different combinations of instruments. With early influences including Russian and Far Eastern music and works by Chopin, Debussy developed his own style of harmony and orchestral colouring, derided – and unsuccessfully resisted – by much of the musical establishment of the day. His works have strongly influenced a wide range of composers including Béla Bartók, Igor Stravinsky, George Gershwin, Olivier Messiaen, George Benjamin, and the jazz pianist and composer Bill Evans. Debussy died from cancer at his home in Paris at the age of 55 after a composing career of a little more than 30 years.

Claude Debussy completed his String Quartet in G minor, Op. 10 (L.91), in 1893, when he was 31 years old. It is Debussy's only string quartet.

Prélude à l'Après-midi d'un faune (L. 86), known in English as Prelude to the Afternoon of a Faun, is a symphonic poem for orchestra by Claude Debussy, approximately 10 minutes in duration. It was composed in 1894 and first performed in Paris on 22 December 1894, conducted by Gustave Doret. The flute solo was played by Georges Barrère. The composition was inspired by the poem L'après-midi d'un faune by Stéphane Mallarmé. It is one of Debussy's most famous works and is considered a turning point in the history of Western art music, as well as a masterpiece of Impressionist composition. Pierre Boulez considered the score to be the beginning of modern music, observing that "the flute of the faun brought new breath to the art of music." The work is dedicated to the composer Raymond Bonheur, son of the painter Auguste Bonheur. Debussy's work later provided the basis for the ballet Afternoon of a Faun choreographed by Vaslav Nijinsky and a later version by Jerome Robbins.

The Première rhapsodie (First Rhapsody), L. 116, CD. 124, by Claude Debussy is a piece for accompanied clarinet. Composed between December 1909 and January 1910, it was dedicated to the French clarinet professor Prosper Mimart. In 1909, Gabriel Fauré, Director of the Conservatoire de Paris, named Debussy to its board of directors (le Conseil Supérieur). One of Debussy's first duties was to supply two works for the next year's clarinet examinations. The Rhapsodie was first performed as part of the examinations on July 14, 1910. The original composition was for clarinet and piano; Debussy published his own orchestration of the accompaniment in 1911, after the official premiere with Mimart. In 1901, Debussy had been commissioned to write a work for alto saxophone and orchestra by Elise Hall, but never finished the 1903 draft during his lifetime. This "Second Rhapsody" was later completed by Jean Roger-Ducasse as Rapsodie pour orchestre et saxophone.

La mer, trois esquisses symphoniques pour orchestre (French for The sea, three symphonic sketches for orchestra), or simply La mer (The Sea), L. 109, CD. 111, is an orchestral composition by the French composer Claude Debussy.

Rhapsodie for saxophone and orchestra, L.98, also known as Rhapsodie mauresque or Rhapsodie orientale, is a piece for alto saxophone and accompaniment by Claude Debussy. Completed in solo and piano form in 1911, the piece is most well known through its 1919 orchestration of the accompaniment by Jean Roger-Ducasse.

Suite bergamasque (L. 75) (French pronunciation: [sɥit bɛʁɡamask]) is a piano suite by Claude Debussy. He began composing it around 1890, at the age of 28, but significantly revised it just before its 1905 publication. The popularity of the third movement, Clair de lune, has made it one of the composer's most famous works for piano, as well as one of the most famous musical pieces of all time.
