I normally teach 8-week tango series, however these are on hold until it is safe to dance together once again. I suggest immersing yourself in the Golden Era tango music, such as the orchestras listed on my tango music for dancing page.
Meanwhile be safe and stay sane.
We hope to be back with new beginner series on Sunday afternoons in Boulder. These classes are scheduled so that they don't interfere with the monthly Tea Dances sponsored by Jim Borzym, nor with the twice-monthly Locotango dances sponsored by Halina Morgucz
