Great Sacred Music, a free lunchtime event of spoken word and music for choirs and congregations, is a regular feature of the life at witness of St Martin-in-the-Fields. Each week, a themed programme is offered which combines music with stories of how the pieces came to be written and some reflections on the theme. As well as a celebration of music, it has proved to be instrumental in the mission of St Martin’s, attracting many people to the church. Great Sacred Music offers 52 complete and ready-to-use choral music-themed programmes for occasional celebrations in local churches, or as an alternative to evensong. All the sheet music chosen is available either in the public domain or from major publishers. Scripts for introducing the theme and stories about the music are included. Choral music is one of the great treasures of the Anglican tradition. Great Sacred Music will support the missional work of the church in drawing in people who would not ordinarily attend a service, but who enjoy its rich musical heritage.
