MUSICA 5 SUNSET: The Trio in E-flat, Opus 100, D. 929 by Franz Schubert, 1827

From Wikipedia: Piano Trio No. 2 (Schubert)

The Trio No. 2 in E-flat major for piano, violin, and violoncello, 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. The Trio was among the few of his late compositions Schubert heard performed before his death.[1] It was given its first private performance by Carl Maria von Bocklet on the piano, Ignaz Schuppanzigh playing the violin, and Josef Linke playing cello. 

Like Schubert's other piano trio, in B-flat major, this is a comparatively larger work than most piano trios of the time, taking almost 50 minutes to perform. The second theme of the first movement is based loosely on the opening theme of the Minuet and Trio of Schubert's G major sonata (D. 894). 

The main theme of the second movement was used as one of the central musical themes in Stanley Kubrick's Barry Lyndon. 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, the HBO miniseries John Adams and The Mechanic. It is supposedly based on a Swedish folk song "se solen sjunker" ("See, the sun is sinking") by Berg.

Structure 

The piano trio contains four movements: 

1. Allegro 

The first movement is in sonata form. There is disagreement over the break-up of thematic material with one source claiming six separate units of thematic material while another source divides them into three themes each with two periods. There is to an extent extra thematic material during the recapitulation. At least one of the thematic units is based closely on a theme in an earlier piano sonata. The development section focuses mainly on the final theme of the exposition. 

2. Andante con moto 

The second movement takes the form of an asymetrical-double-ternary form. The opening theme has been used extensively in popular culture.

3. Scherzando. Allegro moderato 

The scherzo is an animated piece in standard double ternary form. 

4. Allegro moderato 

The finale is in an uncommon form where Schubert layers the sonata form with the outline of rondo form. Schubert also includes in two interludes the opening theme of the second movement in an altered version.
