I agree totally with both Rachel and Amir - there is much to be said for technique, but absolutely for feeling comfortable with your own body and how it moves. It's not about 'wow' movements, just about knowing what your body does/doesn't feel comfortable with.
But on the flip side, I've danced solo all my life. I've had no proper training in any style/technique, I've just danced whatever comes out of my heart/soul. I feel completely confident and comfortable with how my body moves, but am not confident dancing solo in front of people unless it's choreographed (and I'm not good at learning choreography, so I'm not that confident even then!) This is because my solo dancing comes from my soul, and as such I feel very vulnerable when solo dancing as my soul is bared, so to speak, and there is much to see for those who can read it.
Does all this make me a better partner dancer? Initially, absolutely not!!! I was so used to moving on my own and having control of my own dance that I REALLY struggled to follow. It took probably 18 months before I grasped the notion of following properly.
Now? I'm probably not the best person to comment on my own dancing. But I know that I enjoy my partner dances. I can follow, and I enjoy the feel of my partner dances. And I am confident to move my body and express myself to the music and my partner. I am confident improvising and interpreting the music within the conversation of the dance.
But I do sometimes get frustrated because there are occasions when I can't dance how I would like to to a piece of music when I'm with a partner. And if I'm dancing to music I've often danced to solo then I would say I'm probably not so good to dance with as I tend to be listening more to what my body wants to do than to the lead. Sorry.
