What now follows is a hymn to the only god Aten, a long aria (alternating between A minor and A major) by Akhnaten, and the central piece of the opera. Notably, it is the only text sung in the language of the audience, praising the sun giving life to everything. After the aria, an off-stage chorus sings Psalm 104 in Hebrew, dating some 400 years later, which has strong resemblances to Akhnaten's Hymn, thus emphasizing Akhnaten as the first founder of a monotheistic religion.
