To get back to E-flat major for the return of Section A, Schubert employs a brilliant enharmonic pivot. He lands on a , transforming it into a dominant pedal point. The right hand spins out chromatic triplets that wind down dynamically from fortissimo to pianissimo , smoothing the transition back into the bright daylight of the primary theme. Section A′: The Exact Reprise (Bars 169–250)
The melody often uses secondary dominants for climactic sequences and "German sixth" chords (at bars 76 and 81) before closing the section. Section B / Trio (B Minor): The piece modulates abruptly to
How do we get back to E-flat major from B minor? Schuber uses an enharmonic pivot of breathtaking ingenuity. The G-sharp diminished seventh (again!) can be respelled as a C-flat diminished seventh . And C-flat is the leading tone to D-flat major, which is the Neapolitan of C, which leads to F... No, simpler: He resolves the diminished chord directly to a C-flat major chord (bar 111), which then becomes the Neapolitan of B-flat (the dominant of E-flat). After a final, shuddering B-flat 7 chord (bars 113-114), we crash-land back into the opening theme.
: The left hand takes over the driving rhythm with syncopated chords, while the right hand plays accented, leaping octaves. The progression sits firmly in B-flat minor using a jagged i – iv – V7 – i cadence. schubert impromptu op 90 no 2 harmonic analysis
The Coda returns to the triplet rhythm but keeps the minor-key gravity of the Trio. Tragic Ending: It closes with emphatic E-flat minor chords
minor for the Trio) to create a dramatic narrative that starts in major and ends "tragically" in
Schubert employs passing chords and gentle chromaticism within the scalar passages to add color, without disrupting the overall stability of the major key. The melody often features descending lines, giving the section a playful yet delicate character. 3. Harmonic Analysis of the B Section (Trio in b minor) To get back to E-flat major for the
A significant early transition occurs from E-flat major to its parallel minor (E-flat minor) , marked by a dynamic shift to pianissimo Harmonic Features:
The Impromptu opens with a fast, scalar triplet theme in the right hand. While the home key is E-flat major, Schubert immediately destabilizes the tonal center using modal mixture. The Diatonic Opening (Bars 1–12)
Schubert pulls off one of his most brilliant harmonic deceptions in this subsection. He modulates from B-flat minor to . Harmonically, F-flat major is the Neapolitan chord ( Section A′: The Exact Reprise (Bars 169–250) The
However, a simple "which notes occur in the bar" can be a misleading criterion for harmonic analysis. To understand the underlying harmony, one must consider the notes that fall on the main beats, as these typically outline the fundamental chord structure.
The piece opens with an unharmonized E-flat in the right hand, instantly establishing the tonic pitch.
