Does anyone here ever wonder why there are so many discussions about cabeceo, and very few discussions about inviting in other partner dances?
Mystique, plain and simple. Like any pastime, tango has its terminology and secret codes – the things that set it apart from other pastimes (in this case, other dances). So, tango dancers like to bring up these elements: reactionaries, to glorify tradition; progressives, to question it; elitists, to establish dominance and exclusivity; beginners, to belong; troublemakers, to get a rise out of others; and so on.
I mean, in my other major hobby – mixology – people discuss traditions that other food-and-beverage hobbyists don't care about. Everybody in those hobbies stirs stuff, for instance, but only mixologists get obsessive about wrist angle. Lots of them use ice, too, but only mixologists are nutty about achieving perfectly clear ice carved a certain way. It's like that.
In the case of cabeceo, its
existence isn't what's talked about – as others have pointed out, any dance where people hang out in crowded, noisy rooms develops visual invitations. It's the degree of ritualization and glorification above all other forms of invitation that's discussed. Most other dances are very open about what constitutes a visual invitation, and are just as relaxed about verbal ones, but tango elevates the visual invitation.
I think the cabeceo is cool and use it almost exclusively when I invite others. But I'm also fine with being invited verbally by others, and I have never witnessed the pandemonium and social chaos that supposedly descend upon milongas where people don't use it at all. Its perceived value is blown out of proportion to its actual importance.
But again, it's mystique. A rock 'n' roller's thumbs-up would work just fine, but some tango traditionalists would be shocked by its difference from the tango ritual.
