2 in E-flat major for piano, violin, and cello, D. 929, was one of the last compositions completed by Franz Schubert, dated November 1827.

It was published by Probst as Opus 100 in late 1828, shortly before the composer's death and first performed at a private party in January 1828 to celebrate the engagement of Schubert's school-friend Josef von Spaun.

It has also been used in a number of other films, including The Hunger, Crimson Tide, The Piano Teacher, L'Homme de sa vie, Land of the Blind, Recollections of the Yellow House, The Way He Looks, The Mechanic, Miss Julie, The Congress, the HBO miniseries John Adams, the FX miniseries Mrs. America, two episodes of American Crime Story, as the opening piece for the ABC documentary The Killing Season, used throughout the BBC documentary Auschwitz: The Nazis and 'The Final Solution', and in the 2023 biographical film, Dance First, about Irish playwright Samuel Beckett.

At least one of the thematic units is based closely on the opening theme of the third movement of the earlier Piano Sonata in G major, D 894.

The principal theme is inspired by the Swedish folk song Se solen sjunker, which the composer had heard in the Fröhlich sisters' house, sung by the tenor Isak Albert Berg.
