Video Example 1

Notes
-29 shows a Running Spin Turn slightly different to the one listed in the IDTA syllabus. It features an extra step on the final (&) count, leaving free the Man's RF back and the Lady's LF forward. 

Other than this final (&) count, the timing and alignment of this video example is identical to what is described in Guy Howard's 
The Waltz and Basic Principles.
