I'm Scott Yoo. Join me on a trip through Buenos Aires to learn the tango. This is all part of getting to know Astor Piazzolla, an Argentine composer who fell in love with tango. The violín-corneta. Have you ever seen one of these? I've never - I've never seen this before. It is like the love child of a trumpet and a violin. ♪♪ Now Hear This "Piazzola's History with Tango" on Great Performances. ♪♪
