Hailing from the Northeast of Argentina and Southern Brazil, Chamamé is a spirited, accordion-led rhythm that sounds like a cross between a waltz and a polka, but with a complex Guarani-influenced swing. It is faster than the Guarânia and more rhythmically "jagged" than a standard waltz. The rhythm is characterized by a strong syncopation where the bass hits the first beat, skips the second, and catches the third. It is the sound of the "Litoral" region, representing a unique cultural blend of European immigrant instruments (accordion/concertina) and Indigenous rhythmic sensibilities.
