Christian music has been a long time tradition for Christians to express either personal or a communal belief regarding Christian life and faith. Common themes of Christian music include praise, worship, repentance and lament.
Like other forms of music, the creation, performance, significance and 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 as entertainment.
One of the most prevalent uses of Christian music is during church worship or other gatherings. Most Christian music involves singing, either by the entire congregation or by a group of people such as a choir. It is frequently accompanied by musical instruments or a cappella singing. One of the earliest forms of worship music in the church was the Gregorian chant which was known for its very monophonic sound.
In the present day, various genres of music originally related to pop rock have been created under the label of Contemporary Christian Music. When a song is identified as a Christian song, it takes into account the lyrics, the song writers and the performers, rather than musical style. Therefore Contemporary Christian Music can be said to be diverse and there are Christian songs that are sung to the rhythm of salsa, rock, folk, hip-hop rap and pop.
