This book is an attempt to dive into the roots of tango to help understanding how such a characteristic style originated: where came this african-named style from? Which mixture allowed tango to emerge? How did this unprecedented phenomenon occur? What was the uplift? Which were the influences? Which idiosyncrasy accompanied this process? Which social background escorted its evolution? It's an invitation to spy into the historical foundation of tango to reconstruct the history, the development and the actuality of a music and dance style, which remains over the times one of the strongest basis of Argentina's culture and even a cliché of its capital, Buenos Aires. From the origins through the lyrics, the dance, vocal- or instrumental tango, the typical instruments and ensembles in each decade, the influence and repercussion of tango and its connection to other styles.
