According to my ever-at-hand "Harvard Brief Dictionary of Music,"
"Krakowiak, Cracovienne (kra-KAW-vyak, kra-ko-VYEN). A Polish dance
named after the city of Cracow. The music is in quick 2/4 time. It
was in vogue in the earlier part of the 19th century, and was executed
by large groups, with shouting, improvised singing, and striking of
the heels. Chopin wrote a Krakowiak for piano and orchestra (op.
14)."
"Varsovienne (vahr-so-VYEN:F.). A Polish dance, named after the city
of Warsaw (F., Varsovie), in slow mazurka rhythm, usually with an
accented dotted note on the first beat of each second measure. It was
popular in ballrooms from about 1850 to 1870."
