Symphony no. 2 "Ascensão"

Symphony No. 2, subtitled Ascensão (Ascension), is a composition by the Brazilian composer Heitor Villa-Lobos. Villa-Lobos composed (or began composing) his Second Symphony in Rio de Janeiro in 1917, but the piece was not completed until late in 1943 or early in 1944.

It was first performed on 6 May 1944 in a radio broadcast by the Orquestra Sinfônica da Rádio Nacional, conducted by the composer. The first North American performance took place a little more than six months later, on 26 November 1944 in Philharmonic Auditorium, Los Angeles, by the Janssen Symphony of Los Angeles, conducted by Villa-Lobos. It is the second in a cycle of five symphonies written in the style of Vincent d'Indy.

The symphony takes approximately 50 minutes to perform. This makes it the second-longest of Villa-Lobos' symphonies, after No. 10.
