Yes, it's correct that people say that. It's not right that it is "more correct" though. Here are a few possible origins of that attitude. "more correct": 1) mambo was danced on the 2 ( 2,3,4...6,7,8...) which directly interprets the Tumbao Moderna (the conga rhythm) which accents the following beats: Code: 220.127.116.11.18.104.22.168. ..x...xx..x...xx So if you focus on the conga you could feel on2 to be more correct 2) if you dance on the 1 you are counterpointing the conga but you are directly interpreting the cencerro (cowbell) which goes Code: 22.214.171.124.126.96.36.199. x...x...x...x... given these two styles, there are a couple of arguments that weaken the case for ET2: 1) ET2 is not the same as mambo, it's a hybrid. It catches the conga on 2 and 6 but misses it on 4 and 8. 2) The conga only showed up in the music in the late 1940s, so how "authentic" can it be? Then you can turn the argument back around the other way: 1) Cuban Son was danced contratiempo (2,3,4...6,7,8...) even before the tumbao showed up 2) "Salsa" is an urban dance born in New York. Its Cuban and Puerto Rican antecedents are no less valid, but they weren't called salsa. better for women: A better turn of phrase might be "better for showing off the woman". The theory here is that when you dance on2, the woman's part of most turn patterns happens around beat 1 rather than beat 5. In other words, when the music hits that crescendo around 1, she is spinning or whatever move has been led. So for performance, you could say she gets a better deal. In some sense the dance has become more about her. The flipside of this one is that on1 your musical accents come on your open break, allowing quick flashes of styling to express the musical crescendos and accents. (It looks a bit more like swing to me). better for spins: I agree that ET2 timing is better for spins. To understand this, we have to notice that ET2 is not just on1 shifted. If we took ET2 and moved it to the 1, the basic would go like this 1,2...4,5,6...7 with the break steps on 1 and 5. So the lead for a multiple spin would go 1,2 pause GO... she would have time on 3 to get stable before spinning on 4 and would not have to come out of it until the next 1. Yep, once you learn one way it can be very discouraging to try another way and to have to fight your instincts. For me it was just another interesting thing to try, I had maxed out on a local scale on 1 and wanted something interesting. Back then all my dancing was wooden by my current standards so maybe it didn't take much of a hit! Don't expect your on2 dancing to feel the same as your on1 dancing: if you are listening to the music then they feel very different. Even when your on2 feels as good as your on1 it won't feel the same as it. If you're listening to the music, it's likely that you'll start to feel that some music works better for you on 1 and some on2.
