The tango andaluz is one of the main musical genres which came into the creation of Argentine tango. It became popular in Buenos Aires in the middle of the 19th century through Spanish theater and inspired the creation of local songs which evolved into one of the primitive form of tango criollo.
The history of the tango andaluz is complex and raises many difficult questions including that of the origin and meaning of the the term “tango”. According to the Argentine musicologist Carlos Vega, (1) when Spanish sailors came to South America at the end of the 18th century, they discovered afro-american rhythms which were integrated into their musical tradition along with the word “tango”. This is the origin of the tango flamenco which in itself has little or nothing to do with Argentine tango.
When the tango flamenco was integrated into Spanish theater in the 19th century it went through a process of transformation which led to the creation of the tango andaluz. Because theaters worked with piano and orchestra rather then guitars, the tango flamenco began to incorporate elements of the habanera, a Cuban rhythm which was very popular in Hispanic countries at that time and better adapted to orchestra instruments. This blend of tango flamenco and habanera is at the origin of the tango andaluz which entered Buenos Aires through the genero chico, a short genre of musical play or zarzuela.
In those days when there was no radio, movies or sound recording of any kind, theater was an important vehicle through which new songs were made popular. This is how the tango andaluz entered Buenos Aires where local versions were invented to better reflect the life situations and linguistic expressions of the Porteños. Many of those tangos acriollados were directly based on an original tango andaluz as Carlos Vega pointed out comparing the “Tango de la casera” with “Andate a la recoleta” (1880). Another example of an early tango which is little more then an adaptation of a tango andaluz is “Ay, qué gusto que placer” (1897) which can be compared to “Ar sal’i los nazarenos”.
Other primitive tangos of andaluz influence include “Bartolo” (1900), “El cochero de tramway” (1900), “La morocha” (1905), “Cuidado con los cincuenta” (1907), “Hotel Victoria” (1906) and “El caburé” (19). These are the tangos which were popularized by interpreters such as Angel Villoldo and Alfredo Gobbi. They contributed to the creation of other genres of tango criollo and disapeared around 1910 in favour of another current related to the milonga.
