The fourth movement of Beethoven's Symphony No. 9 in D minor, Op. 125 (1824) — culminating in the famous "Ode to Joy" chorus — is one of the most iconic works in Western music history, and the first symphony to incorporate vocal soloists and a choir. Beethoven, completely deaf at the time of its premiere, set Friedrich Schiller's poem "An die Freude" as a hymn to universal brotherhood.
