This piece by Hans Christian Lumbye is a delightful blend of polka energy and mazurka elegance. It features the characteristic dotted rhythms of the mazurka interspersed with the more driving feel of a polka.
Developing a nuanced understanding of the mazurka's rhythmic flexibility and a clean, sparkling articulation is crucial.
