What is waltz? How to use in English

The word "waltz" originated in Austria during the 18th century. It comes from the German word "walzen," which translates to "to roll" or "to glide." This name was given to the dance because of the smooth, flowing movement of the couples as they waltzed around the floor. The waltz first gained popularity at the Ballhaus in Vienna, where it was performed at aristocratic ballroom events. It quickly spread to other European countries, including Germany, France, and England, and became a symbol of the upper class. The dance consisted of three people, a couple and a third person, called the promenade. The promenade was necessary to keep the rhythm of the dance moving as the dancers switched partners throughout the evening. The waltz underwent many changes over the years, including the introduction of the waltz orchestra and the development of new variations, such as the Viennese waltz and the American waltz. Today, the waltz is a popular ballroom dance enjoyed by people all over the world.
