port areas of Buenos Aires, where waves of Europeans poured into the country mixing various forms of music. The result, tango, came about as a fusion of disparate influences including: old milonga – songs of the rural gauchos habanera – Cuban music polka and mazurka – Slavic music contradanse – Spanish music flamenco – Andalusian Italian folk music That combination of European rhythms, brought to Argentina and Uruguay by traders and immigrants, developed into the swinging milonga around 1900. The milonga quickly became the popular dance of Buenos Aires and slowly evolved into modern tango; since 1930, tango has changed from a dance-focused music to one of lyric and poetry, thanks to vocalists like Carlos Gardel, Roberto Goyeneche, Hugo del Carril, Tita Merello, Susana Rinaldi, Edmundo Rivero and Ignacio Corsini, was equally well known as a folk singer. The golden age of tango (1930 to mid-1950s) mirrored the golden age of Jazz and Swing in the United States, featuring large orchestral tango groups, too, like the bands (known as "Orquestas típicas") led, in particular, by Francisco Canaro, Julio de Caro, Osvaldo Pugliese, Aníbal Troilo, Juan d'Arienzo, and Alfredo De Angelis.
