There are several documents and much footage on YT from tango the 70s, and also of social tango. And in these videos you can clearly see that everyone was dancing on the spot socially back then. The ronda and the walk isn't part of the tango's DNA,
JournalInTime! The ronda was brought to BsAs from Europe by the Guardia nueva; and found its place in the expensive cabarets (not downtown). The Guardia vieja hadn't anything like that. During the tango craze the ronda disappeared again. The tango nuevo of Copes, Todaro, M. Pugliese and Dinzels didn't know the ronda, because that generation saw itself as a revival of the Guardia vieja. It wasn't until the rediscovery of elegant tango in the clubs of Villa Urquiza that the ronda was reintroduced, because they now saw themselves as a revival of the Guardia nueva and tango de salón. Tango has always experienced ebbs and flows, movement and countermovement, instream and outlier niches. Hence my appeal to appreciate tango in all its plurality and diversity. I can understand that
JournalInTime is annoyed by dancers blocking the lanes. But the fact that one is only allowed to dance on the spot in the center of the dance floor essentially is an act of oppression of other tango traditions.
