[Tango-L] What to call the normal tango walking beat?

[Jamie Gifford]

I am interested in what terminology people use to refer to the tango 
walking beat. I'd like to find terms that are precise but which don't 
create unnecessary confusion.

By the "tango walking beat", I mean the natural walking beat that 
usually has a speed of about 1 beat per second, that appears in the 
usual "caminata". I want to distinguish it from the faster (double 
speed) beat that appears in the "corrida".

I have heard some people talk about "slow" and "quick". I am interested 
in more precise terms than this.

An obvious possibility would be to borrow terms from musical theory - 
"half note", "quarter note" or "eighth note" (or minim, crotchet, quaver 
if you are not from the US, or blanca, negra, corchea if you prefer 
Spanish...)

My question is: of those of you that are familiar with the terms "half 
note/minim" and "quarter note/crotchet", which would you associate with 
the normal tango walking beat? Is it a half note or a quarter note or 
something else?
