About the Viennese Waltz
28 bars per minute, 3/4 time. Basic Rhythm is 123 123 (strong accent on 1)
In some countries (for example, Austria) Viennese is known as the Waltz, while Waltz is recognized as English or Slow Waltz. What is now called the Viennese Waltz is the original form of the waltz. It was the first ballroom dance performed in the closed hold or “waltz” position. It is a fast paced (180 beats a minute) rotary dance where the dancers are constantly turning either in a clockwise (natural) or counter-clockwise (reverse) direction interspersed with non-rotating change steps to switch between the directions of rotation. A true Viennese waltz consists only of turns and change steps.
