Schubert Impromptu Op 90 No 2 Harmonic Analysis Now

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.

Key: E-flat major

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: schubert impromptu op 90 no 2 harmonic analysis

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?

Here, Schubert fully embraces the parallel minor.

The analysis is best broken down by its large-scale structure:

| 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) |

This Impromptu is a textbook example of how Schubert used harmony to create a "psychological" narrative—wandering through keys not just to fit a form, but to evoke a sense of longing and searching. Schubert does not treat minor keys as tension

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

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: Key: E-flat major

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

(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.

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.
