We Beat The Bounds (2017). Commissioned by Tate St Ives.A work for local choirs, commissioned by Tate St Ives to celebrate the opening of an extension that doubled the size of the gallery. In the UK the ancient custom of beating the bounds marks the edge of a parish by beating it with a willow wand. Starting from the logia, the choirs repeatedly traced the full extent of the new bounds of the Tate, crossing in the new gallery. The galleries resound to voices and sticks, and are reflected in mirror-tipped wands. The score composed by Gareth Churcher is also mirrored: sung in a round, the notes are inverted horizontally and vertically through successive bars.
