It is in ternary form.

• A[a(measures 1-8) + a1(measures 9-23)]
• B[b(measures 24-31) + b1(measures 32-38)]
• A1[a2(measures 39-46) + a3(measures 47-62)]

The key is C minor. In the A section, the theme is largely characterized by sharp rhythmic ascending and descending figures with accented staccato notes over two-measure phrases. In contrast, the middle section B is centered around a single melody, possessing more vocal elements, akin to a recitative.

From measures 36 to 38, the Neapolitan second chord (N6) effectively transforms into an augmented sixth chord of the dominant seventh, leading to a half cadence. (Note: The C-flat in the left hand at measure 38 would function as a leading tone if it were B natural, but it is inexplicably notated as C-flat.)

While there is a marking "returning to Tempo I" from measures 39 to 40, the interpretation should consider the balance with the significant accelerando from measure 49 onwards.
