Schubert Impromptu Op 90 - No 2 Harmonic Analysis //top\\

The most striking harmonic event is the transition to the "B" section. Schubert moves from the bright E-flat major to a dark, driving .

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.

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) schubert impromptu op 90 no 2 harmonic analysis

Schubert’s preference for moving keys by thirds (E-flat to G-flat or B/C-flat) rather than the traditional circle of fifths.

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 The most striking harmonic event is the transition

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 triplet scales return, but they are now shadowed by the flattened 3rd (G-flat), 6th (C-flat), and 7th (D-flat). Section B: The B-Minor Shift (The Enharmonic Pivot)

Using the pivot between G-flat and F-sharp to bridge distant keys.

The frequent interplay between major and minor modes.
