[Tango-L] Why is it so hard to walk?

[Sharon Pedersen]

I've been watching some new leaders in our community, and they struggle with
walking.  Huge steps leading with their legs, or holding themselves in an
awkward contorted stance and walking with always-bent legs, or taking very
wide steps when walking forwards, or being unable to coordinate to a
relatively slow beat and having to hover the foot in the air waiting for the
beat to catch up before putting it down.  Why is it so hard for people to
walk?

I leave aside the problems for followers in walking backwards as being
obviously a new motion to learn -- but maybe I'm wrong that the follower has
the uniquely difficult walking challenge.  Maybe walking forwards to the
beat of music is inherently difficult as well.

How do you help your beginners to walk reasonably and musically?
