Yes, if you dance the Viennese Waltz. But it's not about that; it's about AT.Sorry, but this is an attitude I deeply reject.
Musicality isn't an instrument to perfect AT. Musicality is universal; even your Viennese waltz will benefit from it.
Of course, if you have other dance interests, then musicality can assist those. Why would I specifically learn, say, disco structure, if I have no interest and no interest in dancing 'disco'? Hardly 'universal' unless you aim to be a general musician (and they don't always make good dancers).
