| Technique | Example in Op. 90 No. 2 | |-----------|--------------------------| | | E-flat major → E major (B section) | | Enharmonic Reinterpretation | C-flat major chord (bar 61) heard as B major (dominant of E) | | German Augmented 6th | Bar 18: A-flat – C – E-flat – F# resolves to G (V of F minor) | | Common-Tone Diminished 7th | Bar 36: C°⁷ (C – Eb – Gb – A) resolves to E-flat major chord | | Neapolitan as Structural Pivot | F-flat major in coda (enharmonic to E major from Trio) | | Deceptive Cadence (V – bVI) | B-flat⁷ (V of E-flat) to C-flat major (bar 61) |

The piece ends with a descent into E-flat Minor , finalized by two forceful chords, rejecting the "happy ending" expected of the opening E-flat Major key. Thematic & Rhythmic Analysis

Schubert’s harmonic language is saturated with —the borrowing of chords from the parallel minor while remaining in a major mode. The A section already contains a long passage in E‑flat minor (mm. 25–51), where the triplets continue but the harmony becomes darkly coloured. This episode goes through a complete circle of fifths, touching D♭, G♭, and C♭ in addition to the signature flats.
