The Christian church creates Christian music or adapts existing music for Christian use. Contemporary Christian music explores Christian themes, but not always in the confines of the church. Music makes up a large part of Christian worship and includes the singing of hymns, vocalized psalms, vocal and instrumental versions of spiritual songs for the purpose of uplifting and praising God. Musical instruments often accompany singing in the service, either through live performance or the use of soundtracks. Some churches employ only a cappella music to worship God. On other occasions instrumental music only expresses praise toward God. Churches today use these methods of musical expression in many different combinations to offer their praise to God.
Being Jewish, Jesus and his disciples would most likely have sung the psalms from memory.
