Schubert Impromptu Op 90 No 2 Harmonic Analysis [portable] (2025-2026)

minor , for the Trio. This is a distant relationship to the original 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

Before diving into the harmonic analysis, let's set the stage with some background information. Schubert composed his Op. 90 impromptus in 1827, during a particularly productive period in his life. These pieces were intended for solo piano, and their title, "Impromptu," was chosen by the publisher, rather than Schubert himself. The impromptus are characterized by their poetic, expressive nature and technical challenges, making them a staple of the piano repertoire.

Schubert loves moving to the flat submediant (C Major/Minor from E-flat).

Impromptu Op. 90, No. 2, is written in the key of A-flat major, with a tempo marking of "Allegretto." The piece follows a modified sonata form, comprising an exposition, development, and recapitulation. The structure can be outlined as follows:

Schubert briefly relaxes the tension by shifting to the parallel major (

Summary at a glance

The transition into Section B (m. 83) represents one of the most radical harmonic shifts in the nineteenth-century piano literature. Schubert moves from . The Chromatic Third Relationship (Mediant Modulation) Enharmonically, B minor can be understood as C-flat minor ( ) .

Instead of resolving to major, the material is pulled into the parallel minor key, ending with forceful, dark chords.
