Piano Sonata No. 3 (Chopin)

Frédéric Chopin composed his Piano Sonata No. 3 in B minor, Op. 58, in 1844 and dedicated it to Countess Emilie de Perthuis. It has been suggested that this was his attempt to address the criticisms of his earlier Sonata No. 2, Op. 35. Along with the previous sonata, this is considered to be one of Chopin's most difficult compositions, both technically and musically.

The sonata consists of four movements, a similar structure to the second sonata, with a lyrical largo rather than a funeral march.

Among Chopin's piano sonatas this is the only one ending in a major key. A performance of the work lasts around 25–30 minutes.

The work opens on a martial note, the heavy chords and filigree in the opening of the first movement giving way to a more melodic second theme, eventually leading to the conclusion of the exposition in the relative major, D. This exposition is quite long compared to other sonatas and it may be for this reason that many pianists choose to omit the exposition repeat. Motives of the original theme emerge in the development, which, unconventionally, returns to the second theme (as opposed to the first) for the recapitulation, which is in B major.

The scherzo, in the distant key of E-flat major and in strict ternary form, characterised by ebullient quaver runs in the right hand, with a more demure chordal middle section in B major. If played slowly, the main E-flat major theme sounds somewhat similar to the E-flat major melody from the composer's First Ballade. Unlike the scherzo of the B-flat minor sonata (and, indeed, the rest of Chopin's contributions to the genre outside of the sonatas), it is exceptionally short, typically lasting barely two minutes in performance.

Despite a stormy introduction in dotted rhythm, the largo is serene, almost nocturne-like; an immensely beautiful melody is introduced, followed by a mellow and expansive middle section, again characterised by quaver figuration in the background of an intensely harmonic line, separating the more cantabile outer sections in B major. It is the most musically profound of the movements (Kraemer, 1991), in terms of a sustained melody and innovative harmonic progression; it rivals the extensive first movement in length alone.
