– The ear expects a strong E-flat major resolution, but Schubert resolves V⁷ of E-flat (B-flat⁷) to a C-flat major chord (bar 61), which is enharmonically B major – the Neapolitan of the Neapolitan. This is a harmonic ellipsis .
Final cadence in Eb major. Notice the brief touch of bII (Fb major = E major? No – it’s a Neapolitan in Eb?) Wait – careful: At bar 55, there is a sudden F-flat major chord (spelled Fb-Ab-Cb). This is the Neapolitan of Eb ( N = Fb major ). But since Fb is enharmonic to E, it sounds like an E major chord crashing in – an abrupt, shocking color. It resolves deceptively through Cb (enharmonic to B) to Bb7 (V7) and back to I.
Throughout the piece, Schubert employs a range of harmonic techniques to add color and interest:
