The Symphony No. 9 in D minor: Choral, Op. 125, is the final complete symphony of Ludwig van Beethoven. Completed in 1824, the symphony is one of the best known works of the Western classical repertoire, and has been adapted for use as the European Anthem. It is considered by critics to be one of Beethoven’s masterpieces] and one of the greatest musical compositions ever written. Beethoven started the work in 1818 and finished early in 1824. The symphony was the first example of a major composer using voices in a symphony (thus making it a choral symphony). The words are sung during the final movement by four vocal soloists and a chorus. They were taken from the “Ode to Joy”, a poem written by Friedrich Schiller in 1785 and revised in 1803, with additions made by the composer.
