The Samba music rhythm has been danced in Brazil since its inception in the late 19th century. There is actually a set of dances, rather than a single dance, that define the Samba dancing scene in Brazil; thus, no one dance can be claimed with certainty as the “original” Samba style. Another major stream of the Samba dance besides the Brazilian Samba dancing styles is Ballroom Samba which differs significantly. This style is done with a partner in closed hold or open positions including but not limited to hand to hand hold, or side by side positions.
Samba no pé is a solo dance that is most often danced impromptu when samba music is played. The basic movement involves a straight body and a bending of one knee at a time.
The feet move very slightly – only a few inches at a time. The rhythm is 2/4, with 3 steps per measure. It can be thought of as a step-ball-change. It can be described calling it and-a-one, and-a-two, then back to one. The basic movement is the same to either side, where one foot moves to the outside lifting up just before the first beat (i.e. the right leg moves slightly to the right) and leg is kept as straight as a pole. The other foot moves slightly towards the front, and closer to the first foot.
The second leg bends lightly at the knee so that the left side of the hip lowers and the right side appears to move higher. The weight is shifted to this inside foot briefly for the next “and-a”, then shifted back to the outside foot on the two, and the same series of actions is repeated towards the other side.
