Down the line carnival steps were added and members of Rio's high society decided that once the dance had been modified to use the closed ballroom position it was then a proper dance. Eventually aspects from all these dances and probably others combined emerging as the Samba we know today. Some things the judges watch for in a good Samba are steps like the Volta (crossing in front of the body), the Samba Roll (moving the upper body in a circular motion while going through a six step turn), Botafogo (traveling walk that includes a direction change) and dancers who have a good balance of moving and stationary moves. For more contemporary ballroom dances, the dress is usually very lightweight and moves well with the dancer. A popular look for the top of the dress is either halter-style or sleeves that dangle from the shoulder. Strapless-style dresses are not very common in ballroom dancing, probably because of the risk of falling off during a fast-paced dance or not fitting properly while moving about on the dance floor. This would also explain the counter clockwise movement around the dance floor as the man would've stood on the inside of the circle so he wouldn't inadvertently hit any of the people watching the dancers with his sword as he danced past. In Latin American ballroom the postures vary from dance to dance with some using the closed hold and others where the partners hold each other with only one hand. Men often wore their swords while dancing with a woman and it is believed that this led to a woman placing her left hand on her partner's right shoulder, while grasping his left hand for additional balance. This is also where the concept of men leading on the dance floor was developed. As time passed throughout the centuries, many styles of ballroom dancing were born. Today, the swing dance is still performed in an old-fashioned manner using the exact same techniques developed decades ago. The jive is a very popular form of ballroom dance that is closely related to the swing. It involves several of the same steps and techniques, but is more fast-paced and involves more movements of the arms rather than the legs and feet. While working to help the dancers compete nationally and internationally they also helped to set things in motion to insure the availability of floors, music and locations for a group that turned out to be the backbone of the USABDA, the Social Dancers. The early years for the USABDA only saw a small number of members in New York state, a few in the Washington, DC area and a small number on the west coast.
