This is a story of discovery. It describes how a Welsh choir perfected its music making by deepening the relationships between the members and healing any personal antagonism amongst them. In particular it follows the fortunes of the choir's conductor as, through parallel experiences leading the choir in various competitions and helping injured and dying miners in a horrifying mining disaster, he 'finds his soul' and deepens his understanding of the music his choir is able to make. It uses Henry Vaughan's Seventeenth Century poem 'My Soul' as the basis of the journeys of discovery made by the conductor, his choir and their local mining community.
