The real origin of the Waltz is rather obscure but, it can be traced back as far as 400+ years. The Waltz regained its real popularity in the 20th Century when it blossomed out as the Hesitation Waltz in 1913. Until the development of the hesitation, couples had waltzed in one direction until dizzy and then reversed the spin until ready to drop. The Waltz had degenerated into an endurance contest. The addition of the Hesitation resulted in the Waltz as it is done today. The slow Waltz was once known as the Boston Waltz. Today the slow Waltz is the go to dance for weddings, anniversaries and other formal occasions.
