Sextet was by the Polish composer who has completed how many operas?
Sextet (Penderecki) The Sextet is a two-movement composition for clarinet, horn, violin, viola, cello, and piano by Polish composer Krzysztof Penderecki. The composition was written in 2000 and is, according to some critics, the composer's most substantial chamber work to date.
String Quartet No. 14 (Dvořák) The String Quartet No. 14 in A-flat major, op. 105, B. 193, was the last string quartet completed by Antonín Dvořák, even though it was published before his Thirteenth Quartet (which appeared with the higher opus number 106). Dvořák finished his Fourteenth Quartet in 1895, when he had returned to Bohemia after his visit to America. The gestation of the Quartet had actually begun in America and lasted six months, which was rather protracted for the composer. This Quartet marked an important point in Dvořák's development because he would devote himself almost exclusively to writing explicit program music, namely symphonic poems and operas, afterwards.
