The dance stabilized during the 19th century its popularity was helped along by the music of Josef and Johann Strauss. You can find references to the Waltz that go back more than 400 years, however the popularity of the dance had started to wane until 1913 and the advent of the Hesitation Waltz which, as the name implies, slowed the dance down considerably incorporating hesitations and poses throughout the dance. They also expect the dancers to project the great emotion the dance needs to convey. Although the Tango's moves are staccato you don't want your dance to look mechanical, but rather give the impression of feline grace. The woman should project a haughty attitude while at the same time seeming to meld into the man's body. The instructor will give a sign for each step in much the same way hearing dancers will get a vocal count from their instructor. Deaf and hearing-impaired dance students work had to remain "in time" with or without music. The most important things for teaching these students to dance are a visual count, high quality sound systems and use of sign language. 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. 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. Types of Ballroom Dancing With ballroom dancing growing in popularity, more and more people are choosing to learn how to dance. Until recently, ballroom dancing wasn't an ideal activity for everyone - it was mainly reserved for the older generations and the wealthy. When most people think of ballroom dancing, they tend to think of a gentle trot around the dance floor to slow, acoustic music.
