Drastic changes were made to music as well. Western music theory partly displaced the traditional Eastern concepts. The Protestant missions introduced Christian hymns and other Western songs that created a strong impetus to modernize Korean ideas about music. The organ and other Western musical instruments were introduced in 1890, and a Christian hymnal was published in the Korean language in 1893 under the commission of the Queen Consort. She herself, however, never became a Christian, but remained a devout Buddhist with influences from shamanism and Confucianism; her religious beliefs would become the model, indirectly, for those of many modern Koreans, who share her belief in pluralism and religious tolerance.
