What form does Handel's chorus "Hallelujah" take, given that each verse has its own melodic material?

The correct answer is B, which indicates that Handel's chorus "Hallelujah" features multiple distinct musical sections, each with its own melodic material. This structure allows for variety and keeps the listener engaged, as each verse presents new themes and musical ideas. Rather than repeating the same material or adhering to a more rigid form such as ABA or ABAB, "Hallelujah" showcases a sequence where each part (A, B, C, D) contributes to the overall progression of the piece, reflecting the celebratory and joyous nature of the text.

The chorus's diverse melodic lines work collectively to enhance the text's expression and help to build the climactic moments in the performance. This form is characteristic of many choral works in the Baroque period, where composers sought to create dramatic contrasts and emphasize important sections of the liturgical text through unique musical themes.
