for upper voices, SATB, and piano or chamber ensemble This vibrant nine-movement work presents a collaboration between Bob Chilcott and Charles Bennett that unites upper- and mixed-voice choirs in a multi-faceted exploration of colour. Bookended by a prologue and epilogue, The Rainbow devotes a movement to each of the rainbow's colours, with each one assigned its own identity and framed as an element of the natural world. A richly scored instrumental accompaniment, which may alternatively be performed by piano, demonstrates Chilcott's vivid musical palette and helps to characterize each colour within the over-arching narrative of the value of your own self-expression.
