Franz Schubert's Impromptu Op. 90 No. 2 in Major (D. 899) is characterized by its perpetuum mobile triplet scales and a dramatic shift between major and minor modes. While it begins in a bright
major, its structural and harmonic journey leads to a "tragic" conclusion in
minor, breaking the typical Classical expectation of returning to the home major key. 1. Structural Overview
The piece follows a Compound Ternary (A–B–A') form, with a substantial Coda that serves as a final variation of the B section. Section A ( major): A ternary structure within itself (a–b–a'). Section B (Trio -
minor): A starkly contrasting "storm" section with off-beat accents. Section A' ( major): A return to the opening material. Coda (
minor): A final, aggressive section that firmly establishes the parallel minor. 2. Harmonic Analysis by Section Section A: The Diatonic and Chromatic Scales Exposition (mm. 1–24): The main theme establishes
major through rapid triplets. However, it is highly chromatic, often inserting half-steps and secondary dominants to reach climaxes.
Middle Subsection (mm. 25–50): The music shifts to the parallel minor (
minor), providing a darker, more poignant contrast. It modulates briefly to the submediant major ( major) before returning to
Transition (mm. 75–82): Emphatic German Augmented Sixth chords (mm. 76 and 81) prepare the move away from the home key toward the B section. Section B: The Trio in
Enharmonic Shift: Although the previous section prepares for minor, Schubert uses the enharmonic equivalent,
minor, for the Trio. This is a distant relationship to the original Harmonic Movement: This section establishes minor (tonic) before modulating to its dominant, Internal Progressions: mm. 83–86: Establishes minor using a progression. mm. 87–90: Continues the minor tonality, ending on a chord to maintain tension. Coda: The Final "Tragedy" Minor Resolution: Instead of ending in the bright major of the opening, the Coda (based on the section's material) forcefully pulls the piece into
Final Cadence: The piece concludes with two "forceful closing chords" in
minor, marking an unusual and dark end for a work that began so lightheartedly. 3.

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 schubert impromptu op 90 no 2 harmonic analysis
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

Harmonic Analysis of Schubert’s Impromptu in E-flat Major, Op. 90, No. 2 Franz Schubert’s Impromptu in E-flat Major, Op. 90, No. 2
(D. 899) is a staple of the Romantic piano repertoire, renowned for its "moto perpetuo" triplet scales and dramatic tonal shifts. While it begins with a light, shimmering character, a harmonic analysis reveals a darker undercurrent that eventually consumes the piece, leading to a tragic conclusion in the parallel minor key. Structural Overview The piece follows a compound ternary (A–B–A) form with a distinct Section A (E-flat Major): Characterized by rapid, scale-based triplet passages. Section B (B Minor/Trio):
A starkly contrasting "bohemian waltz" marked by heavy accents and wide-spaced octaves. Section A' (Return to E-flat Major): A restatement of the opening material. Coda (E-flat Minor):
A final, accelerating section that shifts permanently into the minor mode. Harmonic Progression and Key Relationships The Ambiguity of Section A Although ostensibly in E-flat Major , Section A frequently veers into the parallel minor ( E-flat Minor
). The harmonic rhythm is relatively slow, often tethered by a repetitive bass line that grounds the swirling right-hand triplets. A key transitional moment occurs as the music moves through a sequence of secondary dominants to reach a climax, followed by a shift to pianissimo in E-flat minor. The Remote Trio (Section B)
The Trio section is notable for its distant harmonic relationship, modulating from E-flat to
(the enharmonic equivalent of C-flat minor). This section consists of five four-bar phrases that establish B minor before modulating to F-sharp minor Key Modulations: The transition to F-sharp minor is achieved through a chord of V (G# diminished 7th). Counterpoint:
Schubert employs passing tones and neighbor tones (e.g., F#–G–F#) within the inner voices to add melodic interest to the block chords. The Coda: Final Resolution to Minor Franz Schubert's Impromptu Op
Franz Schubert’s Impromptu Op. 90, No. 2 in E-flat Major is a masterclass in perpetual motion and harmonic fluidness. Published in 1827, just a year before his death, it exemplifies Schubert’s unique ability to blend Classical structures with the burgeoning expressive freedom of the Romantic era.
While the piece appears to be a light, bravura study in scales, a deep harmonic analysis reveals a sophisticated exploration of tonal relationships, particularly the tension between E-flat major and its parallel minor, E-flat minor. Structural Overview
The piece follows a Ternary (A-B-A) form with a substantial Coda. Section A: E-flat Major (perpetual motion triplet scales). Section B: B-minor (the dramatic "Trio" section). Section A': Return to E-flat Major. Coda: E-flat Minor (a tragic reversal of the opening). Section A: The Fluidity of E-flat Major
The "A" section is built on a non-stop stream of triplets. Harmonically, it is less about complex chords and more about tonal grounding.
The Diatonic Foundation: Schubert begins with a simple I - V7 - I progression in E-flat major. However, he quickly introduces chromatic passing tones within the scales to blur the lines of the key.
The Shift to G-flat Major: A hallmark of Schubert’s style is "modal mixture." Early in the first section, he pivots briefly to G-flat major (the bIII). This creates a momentary "shimmer" before returning to the home key, signaling that the piece isn't as harmonically stable as it first seems. Section B: The B-Minor Shift (The Enharmonic Pivot)
The most striking harmonic event is the transition to the "B" section. Schubert moves from the bright E-flat major to a dark, driving B minor.
The Relationship: On paper, E-flat major and B minor are distantly related. However, Schubert treats them as enharmonic neighbors. He uses G-flat (the 3rd of E-flat minor) as a pivot to F-sharp, which becomes the dominant (V) of B minor.
The Character: This section utilizes heavy accents and syncopation. The harmony moves through a series of Secondary Dominants, pushing the tension until it reaches a climax that eventually winds back down to the E-flat major scales of the "A" section. The Coda: The Final Transformation
Perhaps the most famous aspect of this Impromptu’s harmonic analysis is the ending. Rather than concluding in the triumphant E-flat major, Schubert shifts the entire theme into E-flat minor.
The Tragic Turn: The triplet scales return, but they are now shadowed by the flattened 3rd (G-flat), 6th (C-flat), and 7th (D-flat).
Finality: The piece ends with a forceful E-flat minor cadence. This harmonic choice transforms the "impromptu" from a lighthearted exercise into a serious, almost desperate work of art. Key Takeaways for Analysis
Modal Mixture: The frequent interplay between major and minor modes.
Enharmonicism: Using the pivot between G-flat and F-sharp to bridge distant keys.
Tertian Relationships: Schubert’s preference for moving keys by thirds (E-flat to G-flat or B/C-flat) rather than the traditional circle of fifths.
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: Tonality is a suggestion, not a rule
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
This is a detailed harmonic analysis of Franz Schubert’s Impromptu in E-flat major, Op. 90, No. 2 (D. 899). This piece is a favorite for examining Schubert’s early Romantic harmonic language—particularly his use of mediant relationships, chromatic voice-leading, and sudden tonal shifts within a largely ternary (ABA) structure.
Below is a structured, paper-ready analysis focusing on harmony, form, and function.
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.
| Feature | Example in the Piece | Effect | |---------|----------------------|--------| | Third-related modulations | Eb → Cm → Ab → Fm | Smooth but unexpected key changes | | Enharmonic respelling | Eb major to B minor (Eb = D#) | Sudden, dramatic contrast | | Neapolitan sixth chord | Fb major (spelled Fb-Ab-Cb) in bars 55 & 185 | Chromatic color, expressive tension | | Augmented sixth chords | German (bar 14) and French (bar 105) | Intense dominant preparation | | Chromatic mediants | Eb to G major (bar 33) | Romantic, lush sound | | Abrupt juxtaposition | End of B section (F# major) to A’ section (Eb major) | Disorienting, magical return |
Though this is a small form (ABA), Schubert outlines three distinct tonal areas in the A section alone:
Schubert loves moving to the flat submediant (C Major/Minor from E-flat).
Key: E-flat major (nominal) → quickly moves to B-flat minor
The piece begins with an implied tonic chord (E-flat – G – B-flat) arpeggiated in triplets. However, Schubert immediately tonicizes B-flat minor (the dominant’s parallel minor).
| Bar Range | Key Area | Harmonic Function | Notable Feature | |-----------|----------|------------------|------------------| | 1–4 | E-flat major | Tonic prolongation (I) | Arpeggiated I – V⁷ – I | | 5–12 | B-flat minor | Modulation via C°⁷ (vii°⁷ of B-flat minor) | Uses melodic minor #6 (G-natural) and #7 (A-natural) to pivot | | 13–20 | A-flat major | Submediant of E-flat, relative major of F minor | Surprise German Augmented 6th (Ger⁺⁶) in bar 18: A-flat – C – E-flat – F# | | 21–28 | F minor | Chromatic mediant of A-flat | Descends via diminished 7ths (D°⁷, G°⁷) | | 29–36 | D-flat major | Flat submediant (bVI of F minor) | Resolves deceptively back to E-flat via a common-tone diminished 7th (C°⁷) | | 37–44 | E-flat major | Neapolitan relationship? No – direct return | Sudden Picardy effect but quickly destabilized | | 45–52 | B major (C-flat major) | Enharmonic shift: E-flat → B is a tritone | Uses F-flat to pivot to E-flat again | | 53–69 | E-flat major | Extended dominant preparation (V⁷) | False arrival at bar 61 (C-flat major chord) |
| Technique | Example in Op. 90 No. 2 | |-----------|--------------------------| | Chromatic Mediant | E-flat major → E major (B section) | | Enharmonic Reinterpretation | C-flat major chord (bar 61) heard as B major (dominant of E) | | German Augmented 6th | Bar 18: A-flat – C – E-flat – F# resolves to G (V of F minor) | | Common-Tone Diminished 7th | Bar 36: C°⁷ (C – Eb – Gb – A) resolves to E-flat major chord | | Neapolitan as Structural Pivot | F-flat major in coda (enharmonic to E major from Trio) | | Deceptive Cadence (V – bVI) | B-flat⁷ (V of E-flat) to C-flat major (bar 61) |
The piece is in E-flat Major and follows a loose A-B-A form (or Rounded Binary).
