in his scherzos, ballades, and polonaises. As titles for independent piano pieces, scherzo (Italian for "joke") and ballade (usually a lyrical vocal work) had no specific meaning for nineteenth-century audiences, so Chopin was free to define these genres himself. Unlike the other composer-pianists of his time, however, Chopin rarely gave public concerts; his performing was generally confined to the salons of wealthy aristocrats and businessmen. Public awareness of Chopin's music came about primarily through its publication, and the process of shepherding his works into print assumed great importance for him. However, this was not simply a matter of converting his manuscripts into printed form. Chopin felt that many performance details regarding expression were not fixed elements of his music, even though they have a substantial impact on the way it sounds. He was inconsistent about including performing instructions in his manuscripts, and when publishers asked him to supply them at the proof stage, he often changed his mind several times. Some musical changes also appeared first in proofs and were never copied into his manuscripts. Moreover, due to the inconsistencies of contemporary copyright law, nearly all of Chopin's works had to be issued simultaneously by publishers in France, Germany, and England in order to discourage piracy.
