Waltz music is a type of dance music characterized by a 3/4 time signature, which means there are three beats in each measure. This rhythmic pattern creates a flowing and graceful feel, making it ideal for couples to dance together. The tempo can vary, but waltzes are typically played at a moderate speed, allowing dancers to glide smoothly across the floor. Originating in the late 18th century in Austria and Germany, waltz music gained popularity in the 19th century, especially through composers like Johann Strauss II. Today, it remains a staple in ballroom dancing and is often featured in classical music concerts and social events.
