Schubert Impromptu Op 90 No 2 Harmonic Analysis Patched
Schubert modulates from E-flat major to its dominant, B-flat major , via a standard pivot chord (E-flat acting as IV in B-flat). This is classical procedure. But the second theme (bar 21) is where things get strange.
Instead of resolving to the home key of E-flat major, the piece ends forcefully in the minor parallel, reflecting what scholars often call a "tragic" arc. 2. Key Harmonic Highlights
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.
After the repetition of Section A, the Coda (m. 251) returns to the dark material of the Trio, now firmly rooted in E-flat minor .
