Dona Nobis Pacem (Grant Us Peace) is a cantata by Ralph Vaughan Williams, written in 1936. It is scored for chorus and orchestra, featuring soprano and baritone soloists. Written in the wake of the Great War and amidst growing unrest across Europe, Vaughn Williams’ piece blends the poetry of Walt Whitman and biblical passages in an exploration of humanity's capacity for violence – and humanity’s yearning for peace. As the choir's voices rise and fall with a sense of both anguish and hope, the brass fanfares evoke the chaos and brutality of the battlefield. Vaughan Williams’ piece remains evergreen, inviting modern audiences to consider as the original audiences did 90 years ago: is war worth the cost?
