If you have ears to hear lively music, you know the almost-magnetic attraction of ragtime.
Ragtime has syncopation. It has energy, it has off-beat notes, and a solid bottom-bass-line. Ragtime is a distinctively-American kind of music, originating in African-American culture.
Ragtime gets its name from being in “ragged time,” with syncopated off-beats, and it was about the most-popular type of music in America by the early 1900s.
