Symphony No. 4 is a composition by the Brazilian composer Heitor Villa-Lobos, written in 1919. This symphony is subtitled A Vitória (The Victory), while its predecessor and successor are subtitled A Guerra (War) and A Paix (Peace), respectively. It is also the fourth in a cycle of five symphonies in the style of Vincent d'Indy.
Villa-Lobos composed his Fourth Symphony in Rio de Janeiro in 1919, beginning in October, as the second in a trilogy of programmatic symphonies based on arguments by . It was first performed at the Theatro Municipal in Rio de Janeiro, together with the Third Symphony, in September 1920 by the Orchestra do Theatro Municipal conducted by the composer.
A recording conducted by the composer lasts just over 30 minutes.
The symphony is scored for a large orchestra and brass band.
The work is in four movements:
The Fourth Symphony employs the principle of cyclic form. The main theme of the first movement recurs in all of the following movements, with the aim of providing unity to the whole work. Moreover, themes from Villa-Lobos's Third Symphony are also quoted here, which has sometimes incorrectly been assumed to imply that these two symphonies were originally a single work.
