TheCredo inE minor (RV 591) is the only extant setting of theNicene Creed byAntonio Vivaldi. Another setting exists (RV 592) but is of dubious authenticity.
Figure 1. Measures 1 and 2 of the Violini I e II staff of RV 591.
RV 591 has four movements. In a style similar to his psalm setting ofIn exitu Israel (RV 604), the first movement adorns the chorus' simple rhythms ofcrotchets andminims with the orchestra playing semiquavers and quavers. The second movement is a brief choral episode in thestile antico, borrowing thematic material from the composer'sMagnificat. The fourth movement is based on a semiquaver-quaver motif similar to the first movement, and closes with a fugue.
Figure 2. Measures 129 and 130 of the Violino I staff of RV 588.
The first (and final) movements open with a motif which bears similarity to a brief passage found in the first movement of theGloria (RV 588).
