Marinera Norteña
This Marinera had its origins in the Tondero of Piura. It acquired characteristics of the Marinera Limeña, and soon enough it became a new variation of the dance. The dance itself tends to be quick-paced and though not as "elegant" as the Limeña, it can also be very stylish. Even though the dance originated in the Northern coasts of the country, it has become quite popular throughout Peru.
It is thanks to that popularity that the Marinera is considered the National Dance of Peru, along with the Peruvian Waltz.
