There are instrumental tangos and vocal tangos. Each orchestra has its own unique style. Troilo evokes a different feeling than Di Sarli, especially when it's a tango with singer. Each dancer feels differently with each orchestra as well as dancing tango, vals and milonga. That's a given.
I agree wth this, but I would add to (or complicate) it a little bit more. While the orchestra is a major variable to the equation, the type of song is everybit as important. You mentioned Triolo, so I ask to listen to these two songs (I'm making the assumption that you have easy access to lots of tango music) by him and tell me if they invoke the same feelings. To me, they do not.
If you have these songs (by Troilo) at your access, compare these two:
Te aconsejo que me olvides
La Bordona
I thought the purpose of a man and woman dancing is to connect with each other and the music. I don't understand what you are hearing differently in a "connection tanda."
Yes, those are both purposes (connecting to each other, and connecting to the music). I'm just not sure they are the only two (but that's the subject for a different debate). One way to explain this comes down to what is the more dominant goal in a given song, connecting to (or possibly interpreting) the music, or connecting to your partner.
A connection tanda for me, is when my primary goal (or more dominant goal) is to connect to my partner. Other songs make me want to focus more on connecting to the music. Obviously, both are always desirable, but for me, different songs will make me focus more on achieving one, more than the other.
The interesting thing, is that if the follower feels similar emotions from the music to what I feel, she will seem to enjoy it quite a bit, even though I was more focused on expressing the music (and she'll often compliment me on my musicality). To be clear you can't ignore connecting to the follower though. It's more about what has the priority (or how the music inspires you).
Here are some more songs for you to compare. They are all by Rodriguez.
Connection:
Mirame De Frente
Yo No Se Porque Razon
Rhythm:
En La Buena Y En La Mala
Jueves
Now this gets rather complicated, (because a song can invoke more than one emotion), but when I DJ, I build tandas based upon an attribute (a connection tanda, a rhythmic tanda, a dramatic tanda, A lyrical tanda), and with in the tanda, I try to pick songs that build on whatever feeling I'm going for. Example, in a rhythmic tanda, each song would have either a slightly higher emo or energy level. In a connection tanda, I'd try to increase the emotion.
Perhaps your short time dancing limits your knowledge of the golden age recordings. Believe me, women want connection so they can fly.
While I'm quite sure that's what
you want, I'm a lot less convinced that's what all women want. Example, a lot of women really like nuevo, (even if its not my favorite). From my perspective, these people are putting a high priority on connecting to (or interpreting) the music, (a lot more than connecting to each other in the traditional sense).
I have never heard "neotango" which is composed for dancers who don't know what tango music is. Alternative music is used to prevent dancers from having to listen to all that old music from the 40s. If it's not tango music, then what you are dancing is something other than tango.
The first sentence in this paragraph is unclear as to what you are trying to say, so I can't comment on it.
About the other two sentences, I'll say that I respectfully (and whole heartedly) disagree with them. I don't think alternative songs are about preventing, as much as it is about trying to expand on what songs tango can be danced to. We also disagree about whether you can dance tango to non-tango song.
As I write this, I'm now laughing at myself for trying to defend alternative music. If you knew how much I sit out alternative tandas (which is a lot BTW), you'd know why I find my defense of it rather funny. Basically, I do find a lot of the alternative music to be crap for tango, but I also find the same to be true for many songs from the Golden Era of tango. I guess I'm just selective about what I really like.
