No, you misunderstand what I meant. I was suggesting that if you were really
free to improvise, then just like monkey # 7,854,459 (who has just typed the first Act of Hamlet with only two typos), I might 'improvise' what, coincidentally, is identical to an extended advanced BR tango amalgamation. If you were to observe at the milonga long enough, it should be a mathematical certainty that someone
will - except that very probably it would never happen. We are not free to 'improvise', except with the tango vocabulary, of necessity, that vocabulary is made up of short and mostly simple patterns. The building blocks have to be bigger than just single steps in any available direction, because they could produce BR tango, and that would
never do.
It prompted me to look up 'improvise' in my Concise OED. I found:
- Create and perform spontaneously or without preparation.
- Produce or make (something) from whatever is available.
Is my tango spontaneous? Increasingly, I hope so. Is it made from whatever is available - no, not really. I only use the elements permitted. For elements, you could perfectly easily substitute patterns, and it is a short step from there to figures, and once you have put two figures together, you have satisfied the definition of an amalgamation.
Hmm.
