It was written by Carlos Gardel, the most famous uncrowned king of Argentine tango in Argentine history. The violin leads the melody in a high-profile and restrained way, just like a woman stepping on the tango. She has a noble attitude and refuses to welcome her other half, and she is entangled in it. The piano hits the keys forcefully before the climax of the music, as if taking a deep breath before the next rotation, and then setting out to conquer the dance floor. Since its birth, it has become the first choice dance music for tango in movies, and the melody of combining rigidity with softness seems to adapt to the psychology of each character and the foreshadowing of any scene. This tango-style song, in the form of ABAB, has a lazy and humorous tone in the first paragraph, then goes to the minor in the second paragraph, then to the passionate feeling and then to the major. The counterpoint and harmony of violin and harmonica. The inconsistency and patchwork of the styles of the two parts fully show the tacit cooperation between the two in tango dance. The passion after entering the B section pushes the emotions of dancers and audiences to the highest point. Then suddenly slow down and go back to the first tune. The whole music is euphemistic and moving under the exquisite performance of Paalmann, which shows the exquisiteness of tango dance music. A song is finished, but the melody in my head is lingering, just like a dance that I have never appreciated. There is always only the last step, and I am always disappointed. Listen to it, and only once.
