The Mazurka is a traditional Polish dance in triple time, featuring a dotted rhythm and a certain accentuation on the second beat. Originating in Mazovia near Warsaw, the Mazurka's popularity was established by Chopin who wrote fifty or so for piano from 1830-49. These examples show his wide-ranging orginality in this most elegant and aristocratic of dance forms.
