Schubert now has to climb out of the minor tonality.
Schubert's Impromptu Op. 90 No. 2 in E-flat Major (D. 899) is a masterclass in tonal shifting and structural drama. Most notably, it is famous for starting in a bright E-flat Major
but concluding with a violent, tragic ending in the parallel minor ( E-flat minor Formal Structure The piece follows a Compound Ternary (A–B–A') Section A (mm. 1–82): moto perpetuo characterized by cascading E-flat Major scales in triplets. Section B / Trio (mm. 83–168): A stark, "bohemian waltz" in Section A' (mm. 169–250): A recapitulation of the opening material. Coda (mm. 251–end):
A final transformation based on the Trio's rhythm, ending in E-flat minor. Section-by-Section Harmonic Analysis 1. Section A (E-flat Major)
The opening is defined by a relentless triplet scale. While it begins firmly in E-flat Major, it quickly introduces darker colors. Sub-sections:
The A section itself is ternary (a–b–a). The middle "b" sub-section shifts to the parallel minor (E-flat minor) , creating a "poignant beauty" through its sudden shift to pianissimo Secondary Dominants:
Schubert uses sequences of secondary dominants to drive the melodic peaks before returning to the tonic. Transition:
The section closes with oscillating figures that act as a bridge into the dramatic Trio. 2. Section B / Trio (B minor) The Trio provides a heavy, "tempestuous" contrast. Tonal Shift: The shift from E-flat Major to
is a distant, chromatic relationship (enharmonically E-flat major to C-flat minor). Key Modulations:
It begins by establishing B minor through strong accents on the second beat. It eventually modulates to its dominant, F-sharp minor (mm. 83–102). A dramatic climax occurs featuring a Neapolitan cadence
(mm. 114–115), highlighting the "anguish" of this section. האוניברסיטה העברית בירושלים 3. The Coda (E-flat minor)
In a subversion of classical expectations, the piece does not end "happily" in E-flat Major. Final Tonality:
The Coda returns to the triplet rhythm but keeps the minor-key gravity of the Trio. Tragic Ending: It closes with emphatic E-flat minor chords
, a rare move for a piece that began in the major key, symbolizing a journey toward "alienation" or "tragedy". of the modulations in the Trio section?
The Tragedy of Schubert's Impromptu in E-flat major, D. 899 No. 2
Schubert's Impromptu Op. 90 No. 2 in E-flat Major (D. 899) is a swift moto perpetuo structured in a ternary (A-B-A') design
. It is technically demanding, often rated at a high difficulty level (e.g., Grade 10 on the RCM syllabus Sectional Analysis Section A (E-flat Major): Structure:
This section itself follows a compound ternary form (a-b-a'). It opens with rapid, scale-based triplets in E-flat major. Modulation:
A significant early transition occurs from E-flat major to its parallel minor (E-flat minor) , marked by a dynamic shift to pianissimo Harmonic Features:
The melody often uses secondary dominants for climactic sequences and "German sixth" chords (at bars 76 and 81) before closing the section. Section B / Trio (B Minor): The piece modulates abruptly to schubert impromptu op 90 no 2 harmonic analysis
(the enharmonic equivalent of C-flat minor). This provides a stark, "all'ongarese" (Hungarian style) contrast to the fluid A section. Structure: It consists of multiple four-bar phrases. Harmonic Path:
It establishes the tonic (B minor) and eventually modulates to its dominant, F-sharp minor . Some analysts interpret the internal harmony as using a iv chord with an added 6th i v raised to the a d d 6 power ), a signature Schubertian technique. Section A' and Coda:
The original A section returns with its characteristic swirling triplets. Conclusion: The piece ends with a
that is a variant of the B section. Unusually for a work that begins in a major key, it concludes forcefully in E-flat minor , subverting standard classical expectations. Summary of Harmonic Structure Primary Key Key Features E-flat Major Rapid triplets; moves into parallel E-flat minor.

Schubert's Impromptu Op. 90 No. 2 in E-flat Major is a masterclass in contrasting musical characters, moving from a light, "moto perpetuo" (constant motion) opening to a dark, tumultuous minor-key conclusion. This harmonic shift is particularly famous because it subverts the era's expectation that a piece starting in a major key should end happily. 1. Formal Structure: Compound Ternary Form
The piece follows a standard A–B–A'–Coda structure, but with unique internal variations:
Section A (E-flat Major): Characterized by rapid, descending scale triplets and arpeggios that feel fluid and etude-like.
Section B / "Trio" (B Minor): A stark contrast in 3/4 time, featuring "bohemian" rhythms with widely spaced octaves and heavy, off-beat accents.
A' Section: A return to the shimmering E-flat major triplets.
Coda (E-flat Minor): Instead of resolving to the home key of E-flat major, the piece ends forcefully in the minor parallel, reflecting what scholars often call a "tragic" arc. 2. Key Harmonic Highlights
The Tonal Leap to B Minor: The transition to the B section is a daring harmonic move. Schubert prepares the listener for C-flat major (the flat submediant) but instead pivots enharmonically to B minor for the Trio.
Internal Modulations in Section A: While Section A is primarily in E-flat major, its middle subsection shifts into E-flat minor, providing a "darker" lyrical contrast before the main theme returns.
Unstable Progressions: The harmonic rhythm is often tethered by a repetitive, insistent bass line, yet the swirling right-hand scales frequently lead the ear through "extraordinary harmonic predicaments" that delay resolution.
B - C# - D Motion: A notable harmonic motif in the B section involves a rising third move ( B→C#→Dcap B right arrow cap C # right arrow cap D ), which drives the tension in the melodic theme. 3.

A variant of the B section material that reasserts the minor mode for an emphatic, "angry" finish. 4. Interpretive Note: "The Lonely Traveller"
Harmonically, the shift from a bright major opening to a "violent" minor ending is often interpreted as a representation of Schubert's own emotional state in 1827—a "lonely traveller" (fremdling) whose pleasant recollections are eventually overtaken by anguish and reality. Traversing Schubert's Opus 90 Impromptus Schubert now has to climb out of the minor tonality
Schubert's Impromptu in E-flat Major, Op. 90 No. 2 (D. 899), is a masterclass in harmonic tension and structural subversion. While it begins with a bright, swirling moto perpetuo in E-flat major, it concludes in a "tragic" E-flat minor, breaking the classical expectation of a happy resolution. Structural & Harmonic Breakdown
The piece follows a ternary (A–B–A') design with an added coda. Primary Key Harmonic Features Section A Major
Characterized by sweeping triplets. Features frequent shifts to
minor and sequences of secondary dominants leading to climaxes. Section B (Trio) B Minor Enharmonically replaces the expected
minor. Uses sharp accents and a "bohemian waltz" rhythm. Modulates through minor and uses Neapolitan cadences. Section A' Major
A literal repeat of the first section, maintaining the "sunny" triplets until the transition to the coda. Coda Minor
Instead of resolving to major, the material is pulled into the parallel minor key, ending with forceful, dark chords. Harmonic Highlights
The Parallel Minor Shift: Early in Section A, the music transitions from
minor, signaled by a shift to pianissimo. This creates an underlying "ominous" quality even in the major sections. Enharmonic Pivot ( to B): Schubert prepares the Trio in minor (the submediant of
minor), but writes it in B minor for easier reading. This shift highlights his "anarchic" approach to traditional tonality.
Trio Progressions: The Trio utilizes complex voice-leading, such as moving from the dominant of
into a "dominant" diminished seventh in B minor. One notable cadence uses the progression to firmly establish
The "Tragic" Ending: The final cadence is a violent descent in minor, a rarity for a piece that starts in a major key. Traversing Schubert's Opus 90 Impromptus
This piece is a dazzling, perpetual-motion study with a deceptively simple right-hand melody over a relentless triplets accompaniment. The harmonic structure is a masterclass in Schubert’s signature techniques: rapid tonal shifts, third-related modulations, and the Neapolitan sixth.
The harmonic language of Schubert’s Op. 90 No. 2 is a perfect bridge between Classical clarity (clear phrase structures, functional harmony in the A section) and Romantic harmonic adventure (third relations, enharmonic modulations, Neapolitan and augmented sixth chords). The piece’s genius lies in how the relentless, toccata-like surface rhythm is underlaid with a deeply expressive and unpredictable harmonic journey—especially the shocking shift to B minor in the trio and the enharmonic tricks that frame it.
Schubert establishes the tonic not with a solid chord, but through a flowing accompaniment that hints at the minor mode immediately.
Though this is a small form (ABA), Schubert outlines three distinct tonal areas in the A section alone:
The analysis is best broken down by its large-scale structure:
The "False Tonic" – The ear expects a strong E-flat major resolution, but Schubert resolves V⁷ of E-flat (B-flat⁷) to a C-flat major chord (bar 61), which is enharmonically B major – the Neapolitan of the Neapolitan. This is a harmonic ellipsis. Schubert's Impromptu Op
Schubert does not treat minor keys as tension that needs to be resolved to a Major key. In this piece, E-flat Major and E-flat Minor are treated as equals. The Trio does not "resolve" into the A section; it merely contrasts with it. The Minor mode is viewed as a valid color, not just a functional dissonance.
Schubert’s harmonic language in this Impromptu is proto-Romantic:
This piece is less about functional harmony and more about harmonic color and narrative surprise – a hallmark of Schubert’s mature style, anticipating Liszt and even Wagner.
Schubert’s Impromptu Op. 90 No. 2 in E-flat Major (D. 899) is structured in a large ternary (A–B–A) form
, famously concluding with a coda that shifts the entire work’s tonal trajectory toward a tragic end האוניברסיטה העברית בירושלים 1. Section A: E-flat Major (mm. 1–82)
The opening section is characterized by a "perpetuum mobile" of rapid, scale-like triplets in the right hand over a steady, dance-like bass. The Cross-Eyed Pianist Tonal Stability: It begins firmly in E-flat Major
, but Schubert quickly introduces harmonic ambiguity by slipping into the parallel E-flat minor Harmonic Language: The meanderings of the triplets are often grounded by secondary dominants that build toward climactic peaks.
The bass line remains repetitive and tethered, providing a rhythmic "anchor" for the serpentine upper-voice scales. The Cross-Eyed Pianist 2. Section B (Trio): B Minor (mm. 83–168)
The middle section provides a stark, "stormy" contrast to the lyrical opening. Key Relationship:
Though technically prepared as if it were in C-flat Major (the flattened submediant of E-flat), it is enharmonically written in B minor , a distant and striking key choice. Phrase Structure:
This section consists of five four-bar phrases. It opens on a tonic B minor chord (i)
and utilizes contrapuntal neighbor and passing tones (like the F#–G–F# movement) to maintain tension. Modulation:
The trio frequently oscillates between the tonic and its dominant key, eventually modulating to F-sharp minor
of V chord. The section concludes with a perfect authentic cadence in the new key (I, bII6, V#, I). 3. Return of Section A and Coda
After the Trio, Section A returns largely unchanged, but its final resolution is subverted. האוניברסיטה העברית בירושלים
Unlike a standard classical return that would end in the home key of E-flat Major, the coda brings back themes from the B minor Trio but shifts them into E-flat minor Final Cadence: The piece ends forcefully in E-flat minor
, a rare move that subverts the listener's expectation for a "happy" major-key ending and reflects the "fremdling" (wayfarer) themes found in Schubert’s Winterreise The Cross-Eyed Pianist measure-by-measure breakdown of the chord progressions in the Trio section? Impromptu Es-dur Op. 90,2
Franz Schubert’s Impromptu in E-flat Major, Op. 90, No. 2 (D. 899) is a masterpiece of the early Romantic era. While it is beloved for its "infinity of melody" and restless energy, its harmonic structure is what truly sets it apart. Schubert moves away from the rigorous motivic development of Beethoven and toward a style based on harmonic wandering and color.
