Although tango music was strictly circumscribed to the tango interpreters, it was the classically trained Argentinian pianist Arminda Canteros (1911–2002) who used to play tangos to satisfy the requests of her father, who could not understand classical music. She developed her own style and had a weekly program of tango music for a radio station in Rosario, Argentina in the 1930s and 1940s. Since tango playing was considered the epitome of machismo, she had to take the masculine pseudonym "Juancho" for the broadcasts.
