Ragtime is an African American–rooted piano style that flourished from the 1890s to the 1910s, characterized by lively syncopation in the right hand against a steady, march-like “oom‑pah” accompaniment in the left hand. Typically written in 2/4 or 4/4 time and notated with straight (unswung) eighth notes, classic rags unfold in multiple 16‑bar strains, often in the form AABBACCDD. The music draws on cakewalk rhythms, marching-band forms, and popular song, and it became a sensation through sheet music, piano rolls, and parlor performance. Scott Joplin, known as the “King of Ragtime,” helped codify the genre’s refined, compositional approach, calling for moderate tempos and a clear, singing melody. Beyond solo piano, ragtime was arranged for small ensembles and orchestras, found a home in vaudeville and dance halls, and laid essential groundwork for early jazz, stride piano, and much of 20th‑century American popular music.

Classic ragtime is a composed, syncopated style of American popular piano music that crystallized in the late 1890s and flourished through the 1910s. It pairs a steady, march-like left hand (bass note plus chord—“oom–pah”) with a highly syncopated right-hand melody that "rags" the beat. Unlike later jazz, classic ragtime is not primarily improvised; it was disseminated as notated sheet music and intended to be played at a moderate, even tempo without swing. Most rags follow a multi-strain march form (often AABBACCDD), with 16-bar sections and a trio that commonly modulates to the subdominant. Its harmonic language centers on diatonic progressions colored by secondary dominants, chromatic approach tones, and occasional diminished passing chords. The style is rooted in African American musical aesthetics and social dance (e.g., cakewalk), while drawing structural cues from European marches and ballroom dances. Though quintessentially a solo piano idiom, classic ragtime was also arranged for small ensembles and bands.

Ragtime song is a vocal, popular-song adaptation of ragtime that incorporates the style’s characteristic syncopated (“ragged”) rhythms into verse–chorus song forms. Compared with purely instrumental ragtime (especially piano rags), ragtime songs typically emphasize singable melodies, clear lyrical refrains, and dance-friendly tempos, while still using off-beat accents, stride-like accompaniment patterns, and sectional contrasts. It emerged in the U.S. commercial music world of Tin Pan Alley and vaudeville-era publishing, overlapping with coon songs and early musical theatre, and it helped bridge late-19th-century popular music and early jazz-era songwriting.
