1. Your Video Lessons are EXCELENT !!!
2. My sugestions for video lessons:
a-The "TANGO-Walk" (Forward, Backward, Side) and the difference between "Tango-Walk" and "Usual-Walk",
b- Tango Steps Theory, - The six Tango Steps :Forward, Backward, Side, Cross, Front, Back. Almost everyone (including tango instructors) mix between the "Forward-Step" and "Front-Step". The tango steps definition of the "Basico" and "Giro".
3. Again, you are doing a great job !!!
