The purpose of this study is to explore and analyze the ars poetica in the work of Eladia Blázquez (1936-2005), and to appreciate to what extent it converges or separates detaches itself from the traditional tango lyrics. Due to her numerous pieces, she is the first and only woman to write both music and lyrics consistently, while proposing a different viewpoint in tone and themes in order to update them to current times. Among them, the major are Buenos Aires, life and identity. The researcher proposes that Blázquez nourished herself on the classics, recreating them while offering new expressive possibilities, shifting at times from their melancholic tone and the moaning sound of the bandoneón, tango’s soul-haunting instrument, to a more hopeful one. Definitely, Blázquez’s renovated vanguard brought about change in Argentinean tango poetry, and the genre back to life when it was agonizing.
