Schubert Impromptu Op 90 No 2 Harmonic Analysis Guide

) of E-flat major—a standard Romantic surrogate key. Schubert takes this relationship a step further by slipping into the minor mode of that distant region ( The B Theme Progressions (mm. 83–168)

Section B abandons the flowing triplets for a sharp, syncopated rhythm. The harmonic language here is highly unstable:

The opening section is characterized by its light, scalar triplets. The harmonic rhythm is relatively slow compared to the melodic activity, relying on simple tonic-dominant relationships, yet it is colored by Schubert’s signature harmonic shifts. The theme starts firmly in major, alternating between V7cap V to the seventh power

Section A is driven by continuous eighth-note triplets in the right hand over a simple, dance-like accompaniment in the left hand. Despite the rapid surface motion, the underlying harmonic rhythm is slow and deliberately structured.

The piece follows 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 piece opens directly on a tonic E-flat major chord in root position ( ) of E-flat major—a standard Romantic surrogate key

Arrives at ii (F minor) – a standard diatonic chord, but approached by the unusual Ab major, creating a smooth chromatic descent: Eb – Cm – Ab – Fm.

The frequent interplay between major and minor modes.

Schubert pivots by treating Eb as D# (enharmonic). D# is the leading tone of E minor, but he lands on B minor (relative of D major). More simply: Eb = D# → leads to E minor? No, he lands on B minor via a deceptive enharmonic respelling of the dominant 7th of Eb as a German 6th in B minor. The effect is a shock.

Schubert Impromptu Op. 90 No. 2: A Deep Harmonic Analysis Franz Schubert’s Impromptu in E-flat major, Op. 90, No. 2 (D. 899), composed in 1827, is a cornerstone of the Romantic piano repertoire. While it is often praised for its technical brilliance and charming, dance-like flow, a detailed reveals a sophisticated structural design that balances light virtuosity with characteristic Schubertian dramatic shifts . The piece is structured as a ternary (A–B–A') form followed by a coda, with a striking contrast between the major-key outer sections and a dark, moody inner section in 1. Overall Structure and Key Centers The piece is divided into three main sections: A Section (mm. 1–82): E-flat major ( Major), featuring cascading triplet passages.

Schubert’s Impromptu Op. 90 No. 2 in E-flat Major (D. 899) is structured in a large ternary (A–B–A) form

The A section ends with an emphatic, unharmonized B-flat octave. Schubert treats this B-flat enharmonically as an . In the context of B minor, A-sharp is the leading tone (
