To be a great lead, do not love the woman you dance with; rather, listen to the music and love it! Beautiful tango is a process of transference - your love for the music will be transferred to the follower, and she will be enchanted.
Although the tango’s origin is still up for debate and I know its backstory is a *tad* misogynistic (depending on which style you dance), I still find the dancers’ lines and accompanying music alluring; not to mention the beautiful moments captured in mediums of pastels, oil, acrylic, and photography.
I will learn it someday. :)
