"Clair de Lune' is actually the third and most famous movement of Claude Debussy's "Suite Bergamasque." Although Debussy wrote the piece in 1890 at the age of 25, it was not published until 1905. By that time it had been partially re-written as well as re-titled. The original name of this piece was "Promenade Sentimentale." The new title for the movement comes from a poem by the same name written by Paul Verlaie and means "moonlight."
