The waltz is often danced to orchestrated music with strong melodic instruments and can be either vocal or instrumental in nature. The first beat of each measure is dominant with a strong accent on the downbeat, with the next two beats being much lighter. The waltz was first developed in Vienna as a fast-paced dance to music of the time. The Waltz came into the United States in the mid-1800s, first appearing as a vigorous, demanding dance. Eventually, it evolved into the slower version we know today.
