Sonata no. 3 in B minor, op. 58

The Piano Sonata No. 3 in B minor, Op. 58, is a piano sonata in four movements composed by Polish composer Frédéric Chopin; it is the second of the composer's three mature sonatas (the others being the Piano Sonata No. 2, Op. 35, and the Sonata for Piano and Cello in G minor, Op. 65). Completed in 1844 and published in 1845, the work is considered to be one of Chopin's most difficult compositions, both technically and musically. The work has a structure similar to Piano Sonata No. 5, Op. 81 by Johann Nepomuk Hummel.
