"Por Una Cabeza" is one of the most famous tangos ever written, composed by the legendary Argentine tango singer Carlos Gardel with lyrics by Alfredo Le Pera. The title translates to "By a Head" and refers to a horse winning a race by a head. This passionate and melancholic melody has been featured in numerous films, most notably in "Scent of a Woman" (1992) where Al Pacino performs a dramatic tango, and in "Schindler's List" (1993). Gardel's composition remains the quintessential Argentine tango known worldwide.
