The tango dance number in "Scent of a Woman" is called "Por Una Cabeza (One Step Away)". Gardel, the uncrowned king of Argentine tango, composed "Por Una Cabeza (One Step Away)", which is a famous tango dance song that has appeared in "Schindler's List", "Scent of a Woman" and "True Lies".

This Tango-style song is in the form of ABAB. The first section presents a lazy and humorous tone. It enters the B section and changes to a minor key, then shows a passionate feeling, and then switches back to a major key. A performance of contrapuntal harmony by violin and harmonica.

Extended information:

The inconsistent and patchwork style of the two parts fully demonstrates the tacit understanding between the two in tango dance. The passion after entering the B section pushed the emotions of the dancers and the audience to the highest point. Then suddenly slow down and return to the first tune to finish. The whole music is euphemistic and exciting under Perlman's superb performance, showing the exquisiteness of tango dance.

It was composed by Argentinian singer Carlos Gardel in 1935 and the lyrics were written by Yafado Lepera. "Por una Cabeza" in Spanish is originally a term for horse racing, which means "one (horse) head short" in length. It is used in songs to express regret for the complicated and difficult relationship between lovers.
