Tarragó Ros was an emblematic figure in the Argentinian folk genre known as chamamé, a traditional form of music that originated in the northeast of the country, specifically in the province of Corrientes. He was best known for his distinctive expression through the accordion, which is a central instrument in chamamé music. Born Antonio Tarragó Ros on September 30, 1923, in Curuzú Cuatiá, Corrientes, he grew up in a musical environment which helped him to cultivate a deep love for his regional music from a very young age.

Throughout his career, Tarragó Ros solidified his reputation as "El Rey del Chamamé" (The King of Chamamé) and was instrumental in popularizing chamamé beyond the rural confines of Corrientes, bringing it to the national stage and even international audiences. His body of work includes numerous albums that showcase his prowess and the infectious rhythms of chamamé that compel listeners to dance and celebrate the rich tradition of Argentinian folk music. With releases such as "Rey del Chamamé," "Chamamé para Todo el Mundo," and "20 Superéxitos Originales," Tarragó Ros demonstrated the enduring appeal of chamamé and played a pivotal role in its preservation and evolution. He passed away on December 19, 1978, but his legacy lives on through the many recordings and the continued appreciation for chamamé music he inspired.
