Jazz worship is a sacred subgenre that sets Christian hymns, psalms, and contemporary worship songs within jazz idioms—swing, ballad, bossa, and gospel-inflected grooves. It retains congregational singability while enriching the harmony with jazz chord color, extended tertian voicings, modal interchange, and reharmonization. Arrangements typically feature small jazz ensembles—piano or organ, guitar, bass, drum set, and often saxophone or brass—supporting melodies drawn from hymnody or modern worship repertoire. Improvisation is present but framed to serve liturgical function: responsive readings, altar calls, communion, and reflective moments. The result bridges church liturgy and jazz aesthetics, emphasizing reverence, uplift, and communal participation.

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.
