Disco is a dance style that became popular during the late 1960's and well into the 1970's. Disco was not only a dance, it was a music, a fashion, and a lifestyle.
There are many symbols associated with Disco. There were clubs that always had a big dance floor, and the floor, along with all the rest of the club, had lights inside it. A very popular symbol is the disco ball, every club had at least one of these revolving, sparkling balls hanging from the ceiling.
Along with disco came a new wave of fashion. Mens shirts were always made of polyester, and had outrageously large collars. These shirts were full of bright colors or had pictures of people or maybe designs on them. These shirts were never buttoned up. It was essential that all men had to expose as much chest hair as possible without being to vulgar. The hair was always slicked back and many wore big gold chains.
Disco music is mostly danced to a 4/4 beat. The steps are simple because there is no fixed routine, only different moves and styles. This is a very social dance because it is easy to have a conversation while dancing. Disco is a dance that is more for entertainment purposes than anything else.
