SDA a cappella is the unaccompanied vocal-harmony tradition within the Seventh-day Adventist (SDA) church. It blends hymnody, spirituals, and Black gospel quartet practice with choral blend and, in some scenes, jazz-influenced harmonies. Typical ensembles range from male TTBB quartets to mixed SATB groups and large choirs. Repertoires emphasize Scripture songs, traditional hymns, spirituals, and contemporary worship pieces, often arranged for close harmony, precise tuning, and text-forward delivery. Outside the United States, especially in parts of Africa and the Philippines, the style incorporates local languages, call-and-response patterns, and regional vocal timbres while preserving the core a cappella ethos.
