Description
Chopin's contributions to sonata form, the principal form of the Classical era, are limited to a few works: the early piano trio, two piano concertos, three piano sonatas, and the late cello sonata op. 65. Of these, the Piano Sonatas opp. 35 and 58 are considered two of Chopin's most distinctive and acclaimed creations.
The Piano Sonata in B-flat minor, Op. 35, was written in 1839. However, the famous "Funeral March" that defines this work had been composed two years earlier. This sonata's unique blend of free and structured form, as well as its passionate expression balanced by clarity, culminates in a highly original final movement: 75 measures of surging, unison eighth-note triplets.
