The Symphony No. 9 in D minor, Op. 125 is the last complete symphony composed by Ludwig van Beethoven. Completed in 1824, it incorporates part of the Ode an die Freude ("Ode To Joy"), a poem by Friedrich Schiller, with text sung by soloists and a chorus in the last movement. It is the first example of a major composer using the human voice on the same level with instruments in a symphony.
The Symphony No. 9 by the composer Gustav Mahler was written in 1909 and 1910, and was the last symphony that he completed. At this point in time, the infidelity of his wife Alma had been revealed to him and this personal crisis led to what is the most intense of all Mahler's symphonies.
Symphony No. 9 in E flat major, Op. 70 was composed by Dmitri Shostakovich in 1945. It was premiered on 3 November 1945 in Leningrad by the Leningrad Philharmonic Orchestra under Evgeny Mravinsky.
