Rainbow Revisited

Marabi is a South African urban dance music that emerged in the townships around Johannesburg during the 1920s. It is built on hypnotic, cyclical chord vamps—often a simple I–IV–I–V loop—played on cheap pedal organs or upright pianos in informal drinking houses known as shebeens. Blending African melodic phrasing and call-and-response with the syncopation and harmonic language of American ragtime, stride, and early jazz/swing, marabi created an irresistibly danceable groove. As the style moved from small shebeen settings to larger ensembles, saxophones, trumpets, guitar/banjo, bass, and drums amplified its energy and helped define what became known as “township jazz.” Marabi’s infectious vamps and social vitality laid the groundwork for later South African genres such as kwela and mbaqanga.

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.
