A sequence of sacred choruses on texts from the prophecy of Isaiah. Pulitzer Prize-winning composer Douglas Moore (Chairman of the Music Department of Columbia University) wrote to Thompson in 1936, saying, "...I want to go on record in writing' as believing that you have written the best modern choral work I have heard. It is good from every point of view. Technical treatment of the voices, understanding and expression of the text, and actual musical content which is fresh and beautiful." His sentiments have been echoed by choral conductors ever since. The Peaceable Kingdom has become established as a masterpiece of unaccompanied choral writing.
