The ugly tone of U.S. politics and need for a fresh sound brings to mind a moment from the mid-1930s in Buenos Aires (BA). It’s early evening and the dance club is empty. Both economy and politics have turned sour during what comes to be known as Argentina’s Infamous Decade. The orchestra begins to jam, much to the staff’s delight. Pianist Rodolfo Biagi has injected a crisp, clean, foot-tapping rhythm—like nothing that’s been heard in BA for years. After conductor Juan D’Arienzo appears and customers roll in, the waiters clamor for the new tune. D’Arienzo is strict about arrangements, so the band is nervous about straying. But when Biagi kicks in and the crowd loves it, the conductor quickly approves. D’Arienzo’s orchestra lands a recording contract and their old-new dance beat proves a huge hit. Soon the salons and clubs are humming again. This moment marks the beginning of tango’s golden age, a twenty-year period in which a synergy of music, song and dance created a performative art combining wide social participation with high artistry. At mid-century, men still outnumbered women at the milongas (tango dance events). By convention, the place to meet a girl and win her over was on the dance floor. Teenage boys thus went to local clubs for instruction several times a week, first learning the “woman’s part” through an apprenticeship to older dancers lasting nine months before leader training began. At these prácticas, accomplished milongueros tutored novices and refined their own skills by partnering with other men. The best male pairs gave demonstrations. Novice training took three years before permission was granted to attend a milonga. Within this cultural milieu a young Jorge Bergoglio (b. 1936) came to love the tango. After more than a few turns on the floor as a fun-loving teen, he joined the Jesuits. Now flash forward eight decades to Rome and a huge flash mob of tangueras y tangueros celebrating Papa Francesco's 78th birthday in St. Peter's Square. "I love the tango a lot," Francis says, "it is something that comes from inside me." A new sound, a new dance coming from the inside out. May a river of movement arise in our time to overcome the politics of fear and resentment.
