The "Golden Age" of tango music and dance is generally agreed to have been the period from about 1935 to 1952, roughly contemporaneous with the big band era in the United States.
Some of the many popular and influential orchestras included the orchestras of Juan D'Arienzo, Francisco Canaro, and Aníbal Troilo. D'Arienzo was called the "Rey del compás" or "King of the beat" for the insistent, driving rhythm which can be heard on many of his recordings. "El flete" is an excellent example of D'Arienzo's approach. Canaro's early milongas are generally the slowest and easiest to dance to; and for that reason, they are the most frequently played at tango dances ( milongas); "Milonga Sentimental" is a classic example.
Beginning in the Golden Age and continuing afterwards, the orchestras of Osvaldo Pugliese and Carlos di Sarli made many recordings. Di Sarli had a lush, grandiose sound, and emphasized strings and piano over the bandoneon, which is heard in "A la gran muñeca" and "Bahía Blanca" (the name of his home town).
Pugliese's first recordings were not too different from those of other dance orchestras, but he developed a complex, rich, and sometimes discordant sound, which is heard in his signature pieces, "Gallo ciego", "Emancipación", and "La yumba". Pugliese's later music was played for an audience and not intended for dancing, although it is often used for stage choreography for its dramatic potential, and sometimes played late at night at milongas.
