The term contemporary worship generally refers to a form of christian worship that emerge within western evangelical protestantism towards the end of the twentieth century. It was originally confined to the charismatic movement, but is now found to varying extents in a wide range of churches, including many that do not subscribe to a charismatic theology. Contemporary worship is generally characterised by the use of contemporary worship music in an informal setting. Congregational singing typically comprises a greater proportion of the service than in conventional forms of worship. Where contemporary worship is practiced in churches with a liturgical tradition, elements of the liturgy are frequently kept to a minimum. The terms historic worship or traditional worship are sometimes used to describe conventional worship forms and distinguish them from contemporary worship.
