Samba
Although samba exists throughout Brazil – especially in the states of Bahia, Maranhão, Minas Gerais, and São Paulo – in the form of various popular rhythms and dances that originated from the regional batuque of the eastern Brazilian state of Bahia, a music form from Cape Verde, samba is frequently identified as a musical expression of urban Rio de Janeiro, where it developed during the first years of the 20th century. Early styles of samba - and specifically samba de roda - are traced back to the Recôncavo region of Bahia during the 17th century, and the informal dancing following a candomblé ceremony. It was in Rio de Janeiro that the dance practiced by former slaves who migrated from Bahia came into contact with and incorporated other genres played in the city (such as the polka, the maxixe, the lundu, and the xote), acquiring a completely unique character and creating the "samba carioca urbana" (samba school) and "carnavalesco" (Carnaval school director). Samba schools are large organizations of up to 5,000 people which compete annually in the Carnival with thematic floats, elaborate costumes, and original music.
Samba (Brazilian dance)
"Samba no pé" (literally, "samba in the foot") is a solo dance that is commonly 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.
