I am one contestant that is common, thinking toward everyone to study some choreographic knowledge, hoping to get the support of everyone, I want to ask how tango is what stalk turn?Thanks

Stalk walks.
Please visit the danceuniverse.TV. Andrew Sinkenson and William Pino will show you what is it . and how to do it .
Initially , Andrew emphasized keeping touch floor, but the rule changed for more attractive outlook now.
When I danced this figure , I gathered my energy, with maximum stride, very quietly and carefully shape my knee and foot ,to close and hunt something...
Said by a newbie, so just for reference.

Books and instructional video with top dancers enable us to expand knowledge within a few months and guide us in practice.
An interesting appearance is that Top latin dancers explained excellent body weight distribution. weight center, movement , speed , rolling, timing... I believed , sports and dances involve common rules. The solutions were always found in varying fields.
