His oeuvre revolutionized the traditional tango into a new style termed nuevo tango, incorporating elements from jazz and classical music. A virtuoso bandoneonist, he regularly performed his own compositions with a variety of ensembles.

In 1992, American music critic Stephen Holden described Piazzolla as “the world’s foremost composer of tango music”.

His mother was the daughter of two Italian immigrants from Lucca in Tuscany.
