UKDancer, you may find this thread somewhat interesting. http://www.dance-forums.com/showthread.php?t=30478 The evolution of AT, and the multiple ways of dancing it, makes it hard to know where to start. Personally, I think anyone arguing that there is one right way to do just about anything is on very unstable ground . Their Ho is untenable. (Ho is statistics speak for "null hypothesis", in case that was never followed up on.) I've written this before... I think it is unfortunate that this is taught. On the other hand, I've had one woman tell me she could follow so well because she watched my shoulders. But then, that's something you can't do in "close embrace". I have been very surprised at the similarities of instruction in many dance texts (some of them with "ballroom" in the title!) when it comes to fundatmentals, and what I was taught in my AT classes. Other things are different. I don't think of AT as a latin dance and will give the minimization of hip movement as perhaps the main reason. The prominence of the German bandoneon in the music, and the lack of percussion are other things that are "non latin". And the dance reflects the music. Hey, does anyone think of Italy as a Latin country? (Really, I don't. But I'm curious, too.) The Italianization of Tango with the deemphasis of African movements was was of the main phases in the early development of AT. But, you know, doesn't matter so much what you call it. It is what it is.
