"Por Una Cabeza" - "One Step Away", this gorgeous, noble and moving tango song, has appeared in many movie soundtracks. It is the ultimate representative of Argentine tango dance music and is also loved by music fans all over the world. The most well-known and deeply loved tango melody was composed by Carlos Gardel, the most famous and uncrowned king of Argentine tango in the history of Argentina.

The violin leads the melody in a high-profile yet restrained manner, like a woman dancing in a tango. She has a noble step and a disdainful attitude. She is eager to welcome or refuse her dance partner, and is entangled in it. The piano is before the climax of the music. Powerful keystrokes, as if taking a deep breath before the next spin, and then setting off to conquer the dance floor.

Since its birth, it has become the preferred dance music for tango in movies. The soft and steely melody seems to adapt to the psychology of every character and the foreshadowing of any scene.

This Tango-style song has the form 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. The inconsistent and well-proportioned styles of the two parts fully demonstrate the tacit understanding between the two in tango dancing. 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.

When a song is finished, the melody lingers in the mind, like a dance that is not fully enjoyable, always only missing the last step, and always feeling lost.

Listen to it, you will never hear it again.
