I crossed with two sentences:
Tango is a partner dance and social dance that originated in the 1880s along to the Río de la Plata.
How to dance the Tango.
So, I got very confused because the definite article "the" is not used before proper nouns usually, and "Tango" is a proper noun. Thereby, why does one sentence use "the" and the other not? Is there any rule in this case?
I think that the same happens with the dance named Waltz.
Furthermore, why with some dances, it's not used any article, such as Ballet, gayageum and samulnori?
EDIT: It's been recommended this source:“the top levels of government” -- why not "of THE government"?. Nevertheless, I think this question is more related to the generic topic.
