Hymnals are books or collections that contain hymns, which are religious songs typically sung in worship services. They serve as a guide for congregations, providing the lyrics and often musical notation for various hymns used in different faith traditions. Hymnals can vary widely in content, reflecting the beliefs and practices of specific denominations or communities. Many hymnals also include additional elements, such as prayers, scripture readings, and liturgical instructions. They play a significant role in enhancing the worship experience, allowing congregants to participate actively in singing and expressing their faith through music. Some well-known hymnals are associated with specific religious groups, like the United Methodist Church or the Roman Catholic Church.
