4Assist Our Song combines accessible teaching about the theology and shape of worship with essential information about the forms of music used, including congregational hymns, songs, canticles and psalm chant, and music performed by choirs and musicians. It explores the range of resources available, how to extend repertoire, blending the old with the new, changing patterns of church life, and other practical issues. Its aims are the heightening of the profile of music within the church, increasing the skills and understanding on the part of musicians and choirs, assisting leaders of worship and empowering congregations to see themselves also as 'ministers of music'

It offers practical assistance for the 'delivery' of music - choosing music, making the most of choirs and working with musicians. It will be welcomed by all who lead, provide or curate music in worship, as well as clergy and ordinands who lack musical expertise or confidence.
