Juan Maglio: How "Pacho" Became the Record

Tango Orchestras explores the life and legacy of Juan Maglio, universally known as Pacho: the bandoneón master whose name became so synonymous with recorded music that Buenos Aires locals simply said "give me a Pacho" when buying a record. If you love tango or just great music history, this episode is unmissable — press play now.

Born around 1880 into a working-class Buenos Aires family, Pacho taught himself the bandoneón in secret before rapidly progressing from a 13-button instrument to a custom-built 75-button model. Mastering its notoriously bisonoric mechanics — where each button produces a different note depending on bellows direction — he built a technical command that redefined the instrument's expressive range. His four-piece Orquesta Típica Criolla paired his bandoneón with a violin-cornet hybrid that sliced through noisy cafés, while his recordings translated with remarkable clarity through the era's primitive phonograph technology, turning his name into a byword for the medium itself.

As tango evolved toward the sung canción form in the 1920s, Pacho adapted, collaborating with poets and building a close artistic friendship with Carlos Gardel. He mentored future icons including Aníbal Troilo and Rodolfo Biagi, amassed nearly 900 recordings, and laid the rhythmic foundations that Juan D'Arienzo later revived for a new generation of dancers — ensuring his music still echoes in milongas from Buenos Aires to Tokyo.
