PIANO TRIO IN E-FLAT MAJOR, OP. 100, D. 929 (1827)

Composition dated November 1827; 42 minutes

“To The Snail, where we jubilated till midnight,” wrote Schubert’s friend Franz von Hartmann in his diary, March 26, 1828. Schubert and his friends were marking a milestone at their favorite Viennese watering hole, Zur Schnecke (The Snail Shell) in the Petersplatz. Earlier that day, at 7:00pm, Schubert had mounted a benefit concert devoted entirely to his own music. The Vienna Musikverein placed its hall at his disposal free of charge, and a paying audience heard a substantial mixed program—songs, including the newly written Auf dem Strom for tenor, horn and piano, the first movement of the G major String Quartet, D. 887, the choral Schlachtgesang, and, as the centerpiece, the new Piano Trio in E-flat, D. 929.

The trio was by far the most ambitious work on the program. It was performed by the brilliant young pianist Karl Maria von Bocklet, dedicatee of Schubert’s D major Piano Sonata, D. 850, and members of the renowned Schuppanzigh Quartet—Viennese veterans who had given the premières of Beethoven’s late quartets. March 26 marked the first anniversary of Beethoven’s death. But that night belonged to Schubert. The hall was full, and he cleared 800 florins. To many present, Beethoven’s heir was evident.

The success of this—the only public concert of Schubert’s music in his lifetime—strengthened his growing self-confidence. The previous month, the German publishers Schott of Mainz and Probst of Leipzig had inquired about new works. Schubert offered Schott the E-flat Piano Trio, two string quartets, the second set of Impromptus, two recent fantasias, a comic trio, and a list of operas, a symphony, and a mass—“to acquaint you with my striving after the highest in art.” By May, Schott had declined the trio as “probably too long.” Schubert promptly sent it to Probst, adding detailed instructions—tightening its finale—that continue to provoke debate. Probst issued the work in October 1828, but although Schubert knew publication was imminent, he likely never saw it in print. Not until December 11 did the Vienna publisher Artaria report that copies had reached the city.

The period of the two piano trios—roughly the final eighteen months of Schubert’s life—yielded a remarkable number of masterpieces that stretch the limits of their genres. He completed the final songs of Winterreise, the last three Piano Sonatas, the C major String Quintet, the Symphony in C—the ‘Great’—the Fantasias in F minor for piano duet and in C for violin and piano, the Opp. 90 and 142 Impromptus, the Mass in E-flat, and other large-scale choral works, alongside numerous songs including The Shepherd on the Rock and the poignantly, but posthumously titled Schwanengesang (Swan Song) collection.

Both trios—along with a rejected slow movement of the B-flat, later published as Notturno—were composed within a short span. Documentation is sparse, and the manuscript and parts of the B-flat are lost. The surviving E-flat manuscript is dated November 1827. For the March 1828 concert, Schubert advertised a ‘new’ piano trio, and a first-hand report by Leopold von Sonnleithner identifies it as the E-flat.

Yet an earlier concert on December 26, 1827, in the same hall and with the same group of leading players, also featured a ‘new’ trio. “Recently, a new Trio of mine for pianoforte, violin and violoncello was performed at Schuppanzigh’s [series] and pleased very much,” Schubert wrote to Anselm Hüttenbrenner. “It was admirably executed by Bocklet, Schuppanzigh, and Linke.” This is widely believed to have been the B-flat Trio. Schubert’s first biographer, consulting many of his friends, concluded that it was written in September/October 1827, “a little earlier” than the E-flat. However, it was not to be published until 1836. “One glance at Schubert’s B-flat Trio,” wrote Robert Schumann, “and all the troubles of our human existence disappear; the world shines in new splendor… Time, though producing much that is beautiful, will not soon produce another Schubert!”

From its opening, joyous first theme in octaves on the strings, the Piano Trio in B-flat major, D. 898 unfolds on a grand scale, closer to Beethoven’s Archduke Trio than to the three-movement models of Haydn and Mozart. The radiant second theme, first heard high in the cello’s register, sings expansively. Schubert delights in subtle shifts of tonality, teasing the ear while always returning securely to the home key of B-flat. The slow movement ventures boldly through remote keys, glancing back to the harmonic play of the first. The Scherzo glances back further still to the buoyant spirit of the ‘Trout’ Quintet with what appears to be a loose inversion of this work’s scherzo theme. Its high spirits yield in the trio to a lyrically gliding waltz in the same tempo. The finale, labeled Rondo, offers only two literal statements of its theme, interwoven with development and metrical transformation, unified by the rhythm of its first three notes. As musicologist Alfred Einstein observed, these echo Schubert’s early song Skolie, whose opening words offer a poignant reflection on the life of the composer himself: “Let us, in the bright May morning, take delight in the brief life of the flower, before its fragrance disappears.”

The Piano Trio in E-flat major, D. 929 matches the four-movement design of its companion with a breadth that later prompted Robert Schumann to speak admiringly of Schubert’s “heavenly length,” a phrase that has clung to Schubert’s mature, expansively scaled masterpieces ever since. The opening movement achieves symphonic dimensions—1,868 measures, more than all Beethoven’s symphonies except the Third and Ninth. A fanfare-like unison statement launches the work, followed by a terse cello counter-motif that proves central. This, together with a delicate second theme of repeated notes, first heard in distant B minor before settling into B-flat, generate by far the most development throughout the movement.

The slow movement inhabits the emotional world of the Winterreise song cycle, which Schubert completed in the same month as the trio. Its melody, first sung by the cello over a steady tread, has been traced to the Swedish folksong Se, solen sjunker (“See, the sun sets”), which Schubert heard in Vienna. Schubert carefully extracts elements from the folksong including its slowly trudging accompaniment, transforming its melody into something entirely his own. For its form, Schubert may have taken the funeral march from Beethoven's Eroica symphony as a model and recast its three sections, with the melody, first heard on cello, making its final appearance both compressed and in slower tempo. 

The Scherzo—a scherzo in spirit, but a minuet in tempo, Schubert instructed his publisher—is graceful and light-footed, remarkably so given it richness in canonic writing. It contrasts beautifully with a more rustic trio. Like the previous movements, it closes quietly. After a private performance January 28, celebrating a friend’s engagement, after Schott’s rejection of the manuscript, and the March 26 public concert, Schubert heeded the advice of friends and possibly performers, and advised his publisher that cuts should be made in the finale, the longest of the movements. His cuts total some 100 measures, plus the exposition repeat. The original version has since been reinstated by the editors of the Complete Schubert edition. With its buoyant theme, this expansive music goes through many harmonic changes. The piano writing is brilliant and delicate, even as the sad cello theme from the slow movement reappears at the beginning of a busy development section. This comes as a surprise—a sad, even poignant pause in an optimistic movement. Schubert allows himself one more reflection on the cello folksong melody (“See, the sun sets”) immediately before the music joyously switches to the major key for an invigorating close.

Together, the B-flat Trio and the E-flat Trio stand among Schubert’s most ambitious chamber works—public in gesture, symphonic in scale, yet rooted in the intimate lyric voice that defines him.
