Schubert Impromptu Op 90 No 2 Harmonic Analysis
Here, Schubert fully embraces the parallel minor.
Before diving into specific chords, we must understand the layout. The piece is structured as a Rounded Binary Form (A-B-A’) , though it also carries the DNA of a miniature sonata form without a development section.
The harmonic genius lies not in the return to the tonic, but in the way Schubert leaves it and the path he takes to return.

Franz Schubert's Impromptu Op. 90, No. 2 in A-flat major is a solo piano piece that showcases the composer's mastery of harmony and melodic writing. The piece is characterized by a singing melody, nuanced dynamic shifts, and a range of emotions. This harmonic analysis will explore the piece's chord progressions, tonal harmony, and departures from traditional tonality.
Structure
The Impromptu Op. 90, No. 2 is structured in a modified A-B-A form. The A sections are in the tonic key of A-flat major, while the B section modulates to a series of related keys.
Section A (mm. 1-24)
The piece begins in A-flat major, with a gentle, lilting melody in the right hand accompanied by a steady, pulsing rhythm in the left hand. The chord progression is largely diatonic, with a I-V6/4-I progression in the first four measures:
m. 1: I (Ab major) - 3rd inversion (Ab - C - Eb) m. 2: V6/4 (Eb major) - 2nd inversion (Eb - G - Bb) m. 3: I (Ab major) - root position (Ab - C - Eb) m. 4: I (Ab major) - 1st inversion (C - Eb - Ab)
The A section continues with a series of connected phrases, each with its own unique harmonic interest. Notable moments include:
Section B (mm. 25-44)
The B section begins with a new theme in the key of E-flat major (V of Ab major). The harmony becomes more complex, with a series of secondary dominants and borrowed chords:
m. 25: V (Eb major) - root position (Eb - G - Bb) m. 27: vii°7/5 (Db7) - 3rd inversion (Db - F - Ab - Bb) m. 29: vi (Gb major) - root position (Gb - Bb - Db)
The B section modulates through a series of related keys, including:
Section A' (mm. 45-56)
The final A section returns to the tonic key of A-flat major, with a recapitulation of the opening theme. The harmony is largely similar to the first A section, with a few notable differences:

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 Here, Schubert fully embraces the parallel minor
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.

(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. 90 No. 2 in E-flat Major (D. 899) is a staple of early Romantic piano literature, characterized by its perpetual triplet motion and dramatic shifts between major and minor modes. Formal Structure
The piece is typically analyzed in Compound Ternary Form (A–B–A’), with a distinct coda:
Section A (mm. 1–82): Built in a nested ternary form (a–b–a).
a (mm. 1–25): Establishing the home key of E-flat Major with scale-based triplets.
b (mm. 26–51): Moves to E-flat Minor, introducing a darker, more lyrical tone.
a' (mm. 52–82): Returns to the home key before transitioning to the Trio.
Section B / Trio (mm. 83–158): Set in B Minor, this section contrasts the flowing triplets with a "rough, bohemian waltz" feel, featuring off-beat accents.
Section A’ (mm. 159–242): A varied return of the initial E-flat Major section.
Coda (mm. 243–end): Reasserts themes from the Trio but, unusually for a piece starting in a major key, concludes forcefully in E-flat Minor. Harmonic Analysis
The harmonic language is defined by Schubert's signature use of chromaticism and modal mixture. Key Areas and Modulations
The Tonic (E-flat Major): The opening establishes E-flat Major, though often with a chromatic "serpentine" scale that suggests restlessness.
The Trio (B Minor / Enharmonic C-flat): The shift to B Minor (m. 83) is harmonically striking. It is prepared as C-flat Major but enharmonically transformed to B Minor for ease of reading. This section modulates frequently, specifically moving from B Minor to its dominant, F-sharp Minor (mm. 98–102).
Neapolitan Relations: Significant dramatic climaxes (e.g., mm. 114–115) utilize Neapolitan cadences, emphasizing the tragic weight of the minor key. Significant Chord Progressions
Establishment of Key: The Trio uses clear harmonic cycles to anchor the new tonality, such as the i–bII6–V#–i progression in F-sharp minor. Before diving into specific chords, we must understand
Harmonic Ambivalence: Schubert frequently uses rapid interchanges between major and minor versions of the same motive, creating a sense of "poetic tension".
The Final Cadence: The piece ends with a descent into E-flat Minor, finalized by two forceful chords, rejecting the "happy ending" expected of the opening E-flat Major key. Thematic & Rhythmic Analysis
Triple vs. Duple: While the A section is dominated by triplets, the Trio introduces a waltz-like rhythm where the triplet often falls on beat two, adding a "stamping" accent.
Etude-like Texture: The A section functions similarly to an etude, requiring great wrist flexibility for the continuous scalic figures. AI responses may include mistakes. Learn more Schubert's Impromptu Op. 90 No. 2 Analysis | PDF - Scribd
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.

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:

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.
The A’ section repeats the A section’s harmony almost literally until the coda.
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.
