Cuarteto
Cuarteto (Spanish: quartet), sometimes called cuartetazo, is a musical genre born in Córdoba, Argentina.
The roots of the cuarteto ensemble are in Italian and Spanish dance ensembles. The name was coined because the early dance-hall numbers were invariably four-piece bands (violin-piano-accordion-bass).
Cuarteto is almost always upbeat; its rhythm range is similar to that of modern Dominican merengue.
