A striking modal mixture occurs. Schubert dips into minor, using its flattened sixth degree ( ) to create emotional tension before snapping back to Sub-Section B within Section A (Bars 36–59)
The section concludes with a long, driving pedal point on the dominant (F) of the original key, preparing the listener for the return of the E major theme. 4. The Return: A′ Section (Measures 179–262)
A developmental sequence occurs. Schubert modulates rapidly through G major and E minor via secondary dominants, driving the emotional tension to its peak. schubert impromptu op 90 no 2 harmonic analysis

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. B Section/Trio (mm. 83–172):
[Theme 1: E-flat Major] ---> [Theme 2: B-flat Major (V)] ---> [Codetta: E-flat Major] The Initial Period (mm. 1–14)
The development section takes the listener to C minor and then to D-flat major, creating tension and contrast. This section is particularly notable for its complex harmonic progressions and thematic development. for the most challenging triplet passages
minor. This is a dramatic, often surprising harmonic pivot, highlighting the Romantic tendency for key contrasts.
The work opens in a bright , with a playful, cascading melody of triplet scales in the right hand over a waltz-like accompaniment. However, even this seemingly stable opening contains a seed of harmonic exploration, hinting early on at the remote key of G-flat major—a hint of the drama to come.
For performers and students, studying this piece requires focusing on the lyrical quality of the left-hand melodic line in the B section, while maintaining the light, flowing texture of the right-hand triplets.
Features a classical 4+4 phrase structure. The right hand performs rapid scalar passages over a relatively simple, repetitive bass line that provides a firm harmonic anchor. Key Transitions: Early in this section, there is a poignant transition from E-flat Major to the parallel E-flat minor , marked by a shift to pianissimo Chromaticism: rustic dance rhythm.
Discuss the tied to these harmonic changes.
Schubert initiates a gripping modulatory sequence to return to the home key. He passes through remote tonal areas, utilizing enharmonic spellings of diminished seventh chords as pivot points. The bass line climbs chromatically, building immense tension until it resolves to a prolonged
This section itself follows a compound ternary form (a-b-a'). It opens with rapid, scale-based triplets in E-flat major. Modulation:
Includes sequences of secondary dominants that build toward melodic climaxes. Features emphatic German augmented sixth chords
