Beethoven's ninth symphony

The Symphony No. 9 in D minor, Op. 125 (also known as "the Choral"), is Ludwig van Beethoven's final complete symphony. Completed in 1824, the symphony is one of the best-known works in classical music. It is almost universally considered by critics to be one of Beethoven's greatest works, and many consider it one of the greatest compositions in the western musical canon. 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 text additions made by the composer. In the 2010s, it stands as one of the most performed symphonies in the world.

In 2001, Beethoven's original, hand-written manuscript of the score, held by the Berlin State Library, was added to the United Nations Memory of the World Programme Heritage list, becoming the first musical score so honored.

The Philharmonic Society of London originally commissioned the symphony in 1817. The main composition work was done between autumn 1822 and the completion of the autograph in February 1824. The symphony emerged from other pieces by Beethoven that, while completed works in their own right, are also in some sense musical "sketches" (rough outlines) for the future symphony. The Choral Fantasy Opus. 80 (1808), basically a piano concerto movement, brings in a choir and vocal soloists near the end for the climax. As in the Ninth Symphony, the vocal forces sing a theme first played instrumentally, and this theme is reminiscent of the corresponding theme in the Ninth Symphony (for a detailed comparison, see Choral Fantasy). Going further back, an earlier version of the Choral Fantasy theme is found in the song "Gegenliebe" ("Returned Love"), for piano and high voice, which dates from before 1795. According to Robert W. Gutman, Mozart's K. 222 Offertory in D minor, "Misericordias Domini", written in 1775, contains a melody that foreshadows "Ode to Joy".
