Sinfonia (Symphony) is a composition by the Italian composer Luciano Berio which was commissioned by the New York Philharmonic for its 125th anniversary. Composed in 1968–69 for orchestra and eight amplified voices, it incorporates musical quotations to represent an abstract and distorted history of culture. The eight voices are not incorporated classically but rather speak, whisper and shout excerpts from texts including Claude Lévi-Strauss' The Raw and the Cooked, Samuel Beckett's novel The Unnamable, instructions from the scores of Gustav Mahler and other writings.

La mer, trois esquisses symphoniques pour orchestre, or simply La mer, L. 109, CD. 111, is an orchestral composition by the French composer Claude Debussy.
