The music for this ballroom dance is usually provided by an orchestra that has a piano, guitar, violin, flute and a bandoneon (an offshoot of a koncertina, which looks a little like a small accordion). The bandoneon is essential to Tango music. The Tango has always been a very popular dance with Hollywood moviemakers. For other movies the ballroom dancing is the basis of the story as in Shall We Dance, a Richard Gere, Jennifer Lopez film about a family man who signs up for ballroom dance lessons in the hope of meeting the beautiful woman he has seen through the window of the dance studio on his commute home each night. Often couples would congregate here to socialize and dance with other couples, and it wasn't long before dance competitions gained popularity. There are many different dances and versions of ballroom dancing. Each of these unique dances has specific steps and characteristics that make it different from other dances - but there is one aspect that remains constant throughout each style of dancing. Poise: In smooth dancing, the stretch of the woman's body upwards, outwards and leftwards into the man's right arm will achieve balance and connection with his frame, as well as to project outwards to the audience. Poise like posture and line has everything to do with the image you project as you move around the ballroom. The Fox Trot is danced with the same type of hold that is used in the standard waltz, with a combination of long slow steps and short lively ones. The timing of this ballroom dance is of great importance. The slower steps are done on the heels while the quick steps are done on the toes. The Fox Trot can be danced to most any music regardless of whether it is slow or fast. The foxtrot is one of the most popular ballroom dances, although it is also one of the most difficult to learn. The foxtrot is a very smooth dance with fluid movements, and the movements are "slow, quick, quick, slow". This dance is considered to be elite and one of the most formal, so choosing music can be quite a challenge.
