of the Reformation. Worship in such a context also generally features spoken prayer (either unscripted or prepared), Scripture readings, congregational singing of hymns, and a sermon. Some liturgy is normally used but may not be described as such. The Lord's Supper, or Communion, is celebrated less frequently (intervals vary from once a week to annually according to the denomination or local church). Vestments are less elaborate or absent. Charismatic tradition In Charismatic Christianity (including pentecostalism, the charismatic movement, neo-charismatic movement and certain parts of nondenominational Christianity), worship is viewed like an act of adoration of God, with a more informal conception. Some gatherings take place in auditoriums with few religious signs. There is no dress style. Since the beginning of charismatic movement of the 1960s there have been significant changes to Christian worship practices of many denominations. A new music-centered approach to worship, known as contemporary worship, is now commonplace. This replaces the traditional order of worship based around liturgy or a "hymn-prayer sandwich" with extended periods of congregational singing sometimes referred to as "block worship". The worship has two parts; one in the beginning with music and the second part with sermon and Lord's Supper. In the 1980s and 1990s, Contemporary worship music settled in many evangelical churches. This music is written in the style of popular music, christian rock or folk music and therefore differs considerably from traditional hymns. It is frequently played on a range of instruments that would not have previously been used in churches such as guitars (including electric) and drum kits. Types of Christian worship Regular Sunday services are a part of most traditions. The Eucharist may be celebrated at some or all of these; often it is included either once a month or once a quarter. A few denominations have their main weekly services on Saturday rather than Sunday. Larger churches often tend to have several services each Sunday; often two or three in the morning and one or two in the late afternoon or evening.
