The mazurka (Polish: mazurek, name after Poland's Mazury (Masuria) district; mazurka is the genitive and accusative case of mazurek) is a stylized Polish folk dance in triple meter with a lively tempo, containing a heavy accent on the third or second beat. Its folk originals are: slow kujawiak and fast oberek. It is always found to have either a triplet, trill, dotted eighth note pair, or ordinary eighth note pair before two quarter notes. The dance became popular at Ballroom dances in the rest of Europe during the nineteenth century. The Polish national anthem has a mazurka rhythm, but is too slow to be considered a mazurka.
