Tango is a song-and-dance music from the Río de la Plata region, crystallizing in Buenos Aires (Argentina) and Montevideo (Uruguay) in the late 19th century. It is characterized by a melancholic, dramatic tone; richly expressive melodies; and a distinctive rhythmic feel rooted in the habanera and milonga. Core ensembles feature bandoneón, violin(s), piano, double bass, and sometimes guitar, forming the famed orquesta típica. Across the 1920s–1950s it became a worldwide craze, moving from rough immigrant bars to grand salons and radio, developing highly sophisticated arranging and performance practices. Lyrics often employ lunfardo (Buenos Aires slang) and dwell on urban nostalgia, love, betrayal, and the neighborhood (el barrio). Note on terminology: in flamenco, “tangos” is a distinct palo (song form) with a lively 4/4 compás, often in A Phrygian, closely related in feeling to rumba flamenca. Although it shares the name and a spirited character, flamenco tangos is a different tradition from the Río de la Plata tango described above.

Polka paraguaya is Paraguay’s distinctive take on the European polka, transformed in the Southern Cone into a vibrant dance-music idiom. Unlike the Central European 2/4 polka, the Paraguayan variant is commonly felt in 6/8 and features a hallmark sesquiáltera (hemiola) interplay between 6/8 and 3/4, producing a buoyant, forward-driving swing. The Paraguayan harp (arpa paraguaya) and guitars are core timbral signatures, with violin and sometimes accordion supplementing the ensemble. Two principal subtypes coexist: the faster instrumental galopa (dance-oriented) and the more lyrical polca canción (song form), often sung in Guaraní or in Jopará (a Spanish–Guaraní mix). Melodic lines tend to be diatonic and singable, harmony typically revolves around I–IV–V with occasional dominant preparations, and textures showcase arpeggiation, rasgueado strumming, and characteristic harp glissandi.
