krakowiak - polish folk dance from cracow, in live tempo (i'm totally not familiar with music vocabulary. hope you know what i mean..), measure for 2/4, with syncopic (?? i didn't find a word..) rhythm.
introduced to artistic music by chopin, kurpiński, paderewski...

but krakowiak is also an inhabitant of cracow (me for example :)). exactly: krakowiak is a man, krakowianka - a woman.
