Influence

Many later composers of the Romantic period and beyond were influenced by the Ninth Symphony.

An important theme in the finale of Johannes Brahms ' Symphony No. 1 in C minor is related to the "Ode to Joy" theme from the last movement of Beethoven's Ninth Symphony. When this was pointed out to Brahms, he is reputed to have retorted "Any fool can see that!" Brahms's first symphony was, at times, both praised and derided as "Beethoven's Tenth".

The Ninth Symphony influenced the forms that Anton Bruckner used for the movements of his symphonies. His Symphony No. 3 is in the same key (D minor) as Beethoven's 9th and makes substantial use of thematic ideas from it. The slow movement of Bruckner's Symphony No. 7 uses the A–B–A–B–A form found in the 3rd movement of Beethoven's piece and takes various figurations from it.

In the opening notes of the third movement of his Symphony No. 9 (From the New World), Antonín Dvořák pays homage to the scherzo of Beethoven's Ninth Symphony with his falling fourths and timpani strokes.

Béla Bartók borrowed the opening motif of the scherzo from Beethoven's Ninth Symphony to introduce the second movement (scherzo) in his own Four Orchestral Pieces, Op. 12 (Sz 51).

Michael Tippett in his Third Symphony (1972) quotes the opening of the finale of Beethoven's Ninth and then criticises the utopian understanding of the brotherhood of man as expressed in the Ode to Joy and instead stresses man's capacity for both good and evil.

In the film The Pervert's Guide to Ideology, the philosopher Slavoj Žižek comments on the use of the Ode by Nazism, Bolshevism, the Chinese Cultural Revolution, the East-West German Olympic team, Southern Rhodesia, Abimael Guzmán (leader of the Shining Path), and the Council of Europe and the European Union.
