This will seem like a too obvious topic to discuss but it isn't. Especially reading responses in many threads, it is also obvious each one of us has a different 'dancing' personality. Some are easy to read (hmm like for an example Sweavo's or at least what he projects) and others are not. E.g. none of us might dispute it is great to have musicality in our dancing, but what that musicality is or how much it needs to be will certainly differ. This is one person's take: I don't think it is necessary to understand the lyrics to become a better dancer or to express the music with your dancing. Will it be nice to understand what the singer is crooning? Sure. Will that help make you a better dancer? No. Though music and dancing are intricately intertwined, you can be good at one and suck at the other. I remember one thread where someone had posted about why most musicians don't make a good dancer. It is same as choreography - you can be a good choreographer and not-so-good of a dancer. Or you can be a good performer but a bad social dancer or vice-versa. If you don't know the correct technique or can't lead/follow simple CBL or spin or apply right amount of tension, no matter how much you understand your music, it is not going to help with your dancing. I also think too much emoting/expressiveness in dancing is equivalent of pattern-monkeyness (i.e. excessive focus on one aspect to exclusion of others). As much as it depends on your interpretation of the music, it should also depend on who you are dancing with. What I mean to say by "who you are dancing with" is that how much is your partner able to reflect back the feeling or its expression. It needs to be calibrated and toned downed or upped depending on your dance partner (and I think when we get that calibration right we call it "dance chemistry"). Many times I see one of the two in the pair come across as over the top. That's it for you now. Your take ..
