Jacob Gade (1879-1963) – Danish composer and violinist – is world famous as the composer of Tango Jalousie. In 1925 the Palads Theatre in Copenhagen was the natural choice when the new Zorro film with the superstar Douglas Fairbanks in the title role was to have its Danish premiere. All the sails were set; the conductor of the cinema orchestra Jacob Gade composed a new tango for one of the scenes, and he called it Jalousie – tango tsigane. Since the first performance in 1925, what we now simply call Tango Jalousie has become the absolutely most frequently played piece of Danish music for almost a century. The sheet music was published both in Denmark and internationally, and the gramophone and radio made all the difference; innumerable orchestras, violinists and conductors have dipped into the score in the course of time. And now the turn has come to one of the world’s absolutely leading orchestras, the tradition-conscious Vienna Philharmonic.
