This is an easy, 32-count tango sequence described by Albert Newman of Philadelphia in 1914.
The Position
Tango Position and Closed Position, as illustrated below.
The Footwork
Part I - Three-Step Promenade (8 counts): Promenade three steps along LOD in tango position (1, 2, 3), then point second foot against LOD. Promenade three steps against LOD (5, 6, 7), then point first foot toward LOD. (Position and hand hold are not specified for the promenade against LOD.)
Part II - Rocking Turn (8 counts): Lead steps back left as the Follow steps forward right. Then the Lead rocks forward right, as the Follow rocks back left, turning 1/4 to the right. Repeat three more times, rotating one full turn in total.
Part III - Double Overlapping Step (Scissors Step) (4 counts): Lead crosses left foot in front of right (1), steps side right (2), crosses left foot in front of right (3), then points right to the side (4), as the Follow mirrors him. Repeat opposite, traveling to the Lead's left (5, 6, 7, 8).
Part IV - Walking Pivots (4 counts): Two traveling, half-turning pivot steps, Lead backing and then Follow backing in closed position (1, 2), followed by two promenade steps in tango position (3, 4). Repeat (5, 6, 7, 8). According to Newman, the pivots "should be quite rapid, with the appearance of a whirl, and the forward steps should be long and stealthy."
The Music
No music is specified, so any square tango tune of the era will work.
