Tango music is the most sincere confession of love . It is like a complex and affectionate dialogue, intertwining desire and struggle, proximity and alienation, and expressing every emotion of love with melody。From the streets of Buenos Aires to the stage of the world, tango music carries the multiple aspects of love: the fervor of passion, the lingering of yearning, and even the loneliness of loss.The soul of tango music is to condense these complex emotions into a heartbreaking and moving piece of music.
