Bossa Nova
It has been a long time since I done this dance probably over 30 years ago. As I remember it. I did three different styles.
First there was the Folk Dance style which was a left side, right behind, left side right point side. Then the same starting with the right. This was done to a 1, 2, 3, 4 count.
Then there was a step tap, step tap style with a 1, 2, 3, 4 count.
Then there was my favorite style which I called a triple rhythm style. The basic step went Left fwd. Right side, Left inplace, Right back Right side Left inplace. With a timing of 1&2 3&4. The foot work was ball-flat, ball, ball-flat Some where I have notes on the dance but it may take a little will to find.
I hope my memory served me well it is many years ago. This was back in the days of the Watusi, Pachanga, The Bird, The swim, The Pony, and La Bostella.
