Composition of tango by Maestro Astor Piazzolla, and in this case with an arrangement by José María Gallardo del Rey. In 1954, Piazzolla received a scholarship from the Conservatory of Paris, and due to the lack of opportunities in his country, he decided to travel to France with his wife, two children, and parents. Shortly after, he renounced the scholarship and began studying with the renowned musicologist Nadia Boulanger.
