The Suite bergamasque (IPA: /'bɛʀgamask/) is one of the most famous piano suites by Claude Debussy. It was likely named after Paul Verlaine's poem "Clair de lune", which possibly alludes to a bergamask. It is also commonly believed that the Suite Bergamasque is derived from Fêtes Gallantes, a poem by Paul Verlaine. The suite was composed in 1888 but published in 1903, and consists of four parts, or movements.

1. Prélude
2. Menuet
3. Clair de lune
4. Passepied

Clair de lune is the third movement and the most famous, it means 'Moonlight' in French.

Yes it's also that song from Twilight and Ocean's 11. But please, please don't tell your children that. (Note: I have not watched Twilight)
