The tango is manifested in the lyrics - many of the words used in the tango come from lunfardo (porteños' slang); in the music - the large accordion provided the music from the Río de la Plata with that melancholic and somewhat sullen sound that characterizes tango today; and in the dance - which is seen in tango shows and practiced in milongas).
Tango Shows: Buenos Aires is full of tango houses with live orchestras and dancers. The most important places that offer live shows usually include dinner (with options in Argentine beef or international menus).
Milongas: You may also go to the milongas, places where you dance tango. Many of them organize classes - given by specialized teachers - before the dancing. For beginners and more experienced dancers, the offer includes group or individual classes. Tango, milonga or vals.
