Roberto Firpo is considered to be the first serious musician of tango. Little by little, the unforgettable nights of the cabaret Armenonville saw the birth of what it would be a long list of musicians and styles.
Leopoldo Thompson, a bass player who had joined Firpo’s group, created a special effect striking with the arc and the extended hand the cords of the instrument. That particular sound was named the canyengue effect. The word, very controversial and used and abused too much, has a clear and specific meaning, deteriorated, lethargic. Its application to the rhythm of the tango seems to be a consequence of the turn of the century choreography. The ostentatious dancers showed their skills affecting indolence, laziness, and reluctance. At the beginning of the twentieth century there exist numerous prejudices, among which was the belief that the lower layers of the society produced lethargic and useless individuals. The tango may evolved as a much needed way of expression for a social class.

The situation of postwar period and the international prices of Argentine farming products allowed President Marcelo T. de Alvear to administer a prosperous country without any acute social conflicts. The new ruling class under the conservative regime, one step below the aristocracy, became a tango consumer and constituted the new customer of the night clubs. The cabarets of the nineteen twenties witnessed the arrival of conservatory musicians that were going to give to tango music a greater melodic and sonorous richness.
These are the times of the first book of Borges, Fervor of Buenos Aires, the astonishment of fascism in Italy, and the films of Charlie Chaplin and Rodolfo Valentino. In the nineteen twenties, a melody with a calmer rhythm, to be danced by walking, is the founder of a lineage that persists until the present.

These are the times when Boca Juniors becomes the first Argentine futbol team that tours Europe, when Luis Angel Firpo knocks Dempsey off the ring, when the voice of the tango is Carlos Gardel, and music is Julio De Caro. The Decarean sound becomes the foundation of all the typical orchestras that helped the tango become the music of Buenos Aires. The music that has captivated the entire world with his musical and poetic wealth, with its melodic variety and its unmistakable beat.
