Which American genre is characterized by its syncopated rhythm and was popularized by artists like Scott Joplin?

The genre marked by its syncopated rhythm and most commonly associated with artists like Scott Joplin is ragtime. This style emerged in the late 19th century and is distinguished by its distinct rhythmic pattern, which features a steady bass line paired with a syncopated melody. Joplin, often referred to as the "King of Ragtime," contributed significantly to the popularity of the genre through his famous compositions, including "The Maple Leaf Rag."

Ragtime serves as a bridge between classical music and the jazz that would follow, emphasizing the importance of syncopation—playing off the beat—which created a lively and energetic sound. The genre's influence can be seen across various musical forms that evolved later, illustrating its foundational role in American music history.
