The correct answer is ragtime. Ragtime, a popular musical style in the late 19th and early 20th centuries, played a significant role in shaping various other styles of music, including jazz, blues, and rock and roll. It also influenced country music, although to a lesser extent. Ragtime's syncopated rhythms, lively melodies, and distinctive piano techniques had a profound impact on the development of American music during and after the 1800s.
