Christian music is music that has been written to express either personal or a communal belief regarding Christian life and faith. Common themes of Christian music include praise, worship, penitence and lament and it's forms vary widely around the world. Church music, hymnals, gospel and worship music are a part of Christian media and also include contemporary Christian music which itself supports numerous Christian styles of music, including hip hop, rock, contemporary worship and urban contemporary gospel.
Like other forms of music the creation, performance, significance and even the definition of Christian music varies according to culture and social context. Christian music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes or with a positive message as an entertainment product for the marketplace.
Church music
Among the most prevalent uses of Christian music are in church worship or other gatherings. Most Christian music involves singing, whether by the whole congregation (assembly), or by a specialized subgroup—such as a soloist, duet, trio, quartet, madrigal, choir, or worship band— or both. It is frequently accompanied by instruments, but some denominations such as some Exclusive Brethren, the Churches of Christ, the Primitive Baptists and the Free Church of Scotland prefer unaccompanied or a cappella singing. Other denominations such as Baptists, Methodists, and Presbyterians sing alongside some form on accompaniments. Some groups, such as the Bruderhof, sing songs both with religious and non-religious meanings and words. For them, the act of singing is important. One of the earliest forms of worship music in the church was the Gregorian chant. Pope Gregory I, while not the inventor of chant, was acknowledged as the first person to order such music in the church, hinting the name "Gregorian" chant. The chant reform took place around 590–604 CE (reign of Pope Gregory I) (Kamien, pg. 65–67). The Gregorian chant was known for its very monophonic sound.
