Final answer:
Ragtime is characterized by its syncopated, or 'ragged', rhythms primarily played by the pianist's right hand or on the banjo, being a precursor to jazz with notable figures like Scott Joplin.
Step-by-step explanation:
Ragtime was named for the "ragged" or syncopated rhythms played by the pianists right hand, or the main melody played by the banjo or the band. This uniquely American form of music compelled listeners to dance or tap their feet with its strong beat. Notably, Scott Joplin was a famous composer and performer of ragtime, contributing to its rise in popularity. The spread of ragtime helped foster the environment for the birth of jazz, another uniquely American genre of music.
