RV 591 has four movements. In a style similar to his psalm setting of In exitu Israel (RV 604), the first movement adorns the chorus' simple rhythms of crotchets and minims with the orchestra playing semiquavers and quavers. The second movement is a brief choral episode in the stile antico, borrowing thematic material from the composer's
Magnificat. The fourth movement is based on a semiquaver-quaver motif similar to the first movement, and closes with a fugue.
The first (and final) movements open with a motif which bears similarity to a brief passage found in the first movement of the Gloria (RV 588).
