Second edition cover of "Maple Leaf Rag." It is one of the most famous rags.

Ragtime (or rag-time) is a 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.
