found: New Grove, 2nd ed. WWW site, Nov. 15, 2002(Chaconne: before 1800, a dance, often performed at a quite brisk tempo, that generally used variation techniques, though not necessarily ground-bass variation; in 19th- and 20th-century music, a set of ground-bass or ostinato variations, usually of a severe character; the term is sometimes used interchangeably with "passacaglia"; many composers drew a distinction between the chaconne and the passacaglia, the nature of which depended on local tradition and to some extent on individual preference)
found: New Harvard dict. mus.(Chaconne: a continuous variation form of the Baroque, similar to the passacaglia, based on the chord progression of a late 16th-century dance imported into Spain and Italy from Latin America; although 18th-century theorists attempted to distinguish between the chaconne and the passacaglia, no consistent differences are readily apparent from the 18th century onward, except that the chaconne was more frequently in major)
found: Oxf. comp. mus., 2002(chaconne: a form of continuous variation, similar to the passacaglia, which became popular during the Baroque era; in the 20th century the term was sometimes used to denote an instrumental piece of a particularly austere character using ground-bass variations)
