High Quality Content by WIKIPEDIA articles! Ragtime (alternatively spelled rag-time) is an original musical genre which enjoyed its peak popularity between 1897 and 1918. Its main characteristic trait is its syncopated, or "ragged," rhythm. It began as dance music in the red-light districts of American cities such as St. Louis and New Orleans years before being published as popular sheet music for piano. It was a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music. The ragtime composer Scott Joplin became famous through the publication in 1899 of the "Maple Leaf Rag" and a string of ragtime hits that followed, although he was later forgotten by all but a small, dedicated community of ragtime aficionados until the major ragtime revival in the early 1970s. For at least 12 years after its publication, the "Maple Leaf Rag" heavily influenced subsequent ragtime composers with its melody lines, harmonic progressions or metric patterns.
