Harmonically, the shift from a bright major opening to a "violent" minor ending is often interpreted as a representation of Schubert's own emotional state in 1827—a "lonely traveller" (fremdling) whose pleasant recollections are eventually overtaken by anguish and reality.

Schubert’s harmonic language in this Impromptu is proto-Romantic: Harmonic Analysis of Schubert’s Impromptu in E-flat Major,
- B minor (bar 71)
- D major (bar 72 – the relative major)
- B-flat major (bar 73 – chromatic mediant of D major, flat VI of D)
- G major (bar 74 – dominant of C? No, just a bright shift)
- E-flat major (bar 75 – the home key, appearing like a ghost!)
Rounded Binary Form (A-B-A’)
Before diving into specific chords, we must understand the layout. The piece is structured as a , though it also carries the DNA of a miniature sonata form without a development section. B minor (bar 71) D major (bar 72
minor), but writes it in B minor for easier reading. This shift highlights his "anarchic" approach to traditional tonality.
Return:
Bars 33–48:
The melody rises, and harmony moves to III (G major) – another third relation (from Eb). This is a false dawn. Schubert then slips through G minor (bar 39) and back to V (Bb) by bar 48.
