Following God's instruction, the people and animals leave the ark singing a thankful chorus of Alleluias with more bugle fanfares in B flat. The appearance of the rainbow is accompanied by handbell chimes, a sound which dominates the final stages of the work. In the final canonical hymn, the main tune moves from F major to G major and is sung over reiterated bugle calls, joined by the handbells. In the third verse, the organ provides a brief discordant intervention, "the one jarring note in "Noye's Fludde"" according to the musicologist Peter Evans. Graham Elliott believes that this may be a musical joke in which Britten pokes gentle fun at the habits of some church organists. The mingled chimes of slung mugs and bells continue during God's final valedictory blessing. As Noye leaves, the full orchestra provides a final fortissimo salute, the opera then concluding peacefully with B flat chimes of handbells alternating with extended G major string chords – "a hauntingly beautiful close", says Roseberry.
