Chopin's works for piano and strings were usually made for a specific occasion, and we owe their existence to the repertoire needs of specific individuals. The exception is the Sonata in G minor for cello, the last work by the composer intended for publication, a work reflecting his current style, highly reflective, the result of imagination encroaching into post-romantic areas. Chopin's chamber works belong to the regular concert repertoire. These works were edited by I. J. Paderewski, L. Bronarski, and J. Turczynski.
