Maybe any analogy that we think of will only describe some aspect of the music and there are multiple analogys that are true?
That's probably true.
I wonder if maybe the music can be seen as a key and as a catalyst.
I kind of responded to your post backwards (last to first) so if you read the response below I've tried to put things a different way by describing in terms of energy rather than chemistry. Hopefully it makes more sense that way. Your example of opening doors works well. Especially if you see the opening of multiple doors as the key to increasing the flow of emotion during a dance. You could have a door for each of the senses, doors for different aspects of the music and so on.
You're asking a very interesting question here. If we consider your assumption to be true, wouldn't we notice this mistake when we try to just listen to the music without taking any steps?
Sure. I'm still not clear on the distinction between between passion for the music and passion for dancing or even if there is one. This one has me stumped. Once again, you think you understand something only to realise you don't have a clue.
Going back to a post by Salseralon:
"I have been thinking about this post, my question is, where should the source of passion come from? Is it the 2 individuals love of the dance, or passion that 2 dancers feel for each other to make the salsa passion seem real."

Maybe it 'is' all about emotion. Maybe music is simply the expression of raw emotion that when played becomes entangled with our own feelings which is why it is so hard to talk about without going around in circles like ants on a Möbius strip

. Maybe they are one in the same. Dance is the visual/physical, music is the aural. So to answer you question, we don't need music to be passionate dancers but music certainly amplifies whatever we feel without it. Just as a partner amplifies and changes what we feel compared to when dancing alone.
Back to the energy aspect. Maybe there is no need for a distinction. It's all energy (light, sound, vibrations). When we are exposed to energies with familiar and pleasing vibrations to our own then those energies are amplified within us. It could be your partner, the music or both. Perhaps on some level being a passionate dancer is about being aware of this effect and letting it influence your actions in a positive way. We could say that a potentially passionate dancer would have an awareness of the effect music & dance have on them. The next step would be to learn how to express it; to translate the emotional into the visual.
Right, passion is only one very specific of a vast array of emotions. So I'm mostly talking about the emotions that the music creates. And only sometimes stray into the specific emotion named passion, but then I try to make it obvious.
I'm not sure what you mean chrisk...could you put it a different way?
Not completely, salsa means sauce, but spice would be especia and flavour is rather the often talked about sabor.
Thanks. Sauce has flavour though doesn't it? Sauce can be spicy as well as sweet. It can be many things depending on your taste. Sensual, hot, racy, mellow, take your pick.
I was rather thinking if there's any connection between the passion in our dance and the often mentioned 'flavour' that you can see in some dancers.
Isn't flavour a product of expression? Trust me, it would be a little scary for some to let their passion run free on a crowded floor, especially if you are excitable or a bit of a nutter.
Right, but I wonder how many members of SF have been afraid of us and are afraid of dancing with us in the future. But then again it's for me just about exploiting and trying to understand the emotional side of the music.
Hahaha. I hear you chrisk. There's nothing wrong with trying to understand something you are curious about even if it does make people think you are weird.
And yes, the posts are getting longer again. This one is huge! We don't have to reply to 'everything' you know even though it's hard to see anything in your posts that can be left without a response. I did try to merge some questions into one so if I've missed any of your points please let me know.
