Most organs in Europe, the Americas and Australasia can be found in Christian churches or Jewish synagogues. The introduction of church organs is traditionally attributed to Pope Vitalian in the 7th century. Due to its ability to simultaneously provide a musical foundation below the vocal register, support in the vocal register, and increased brightness above the vocal register, the organ is ideally suited to accompany human voices, whether a congregation, a choir or a cantor or soloist. Most services also include solo organ repertoire for independent performance rather than by way of accompaniment, often as a prelude at the beginning the service and a postlude at the conclusion of the service.
Today this organ may be a pipe organ
