Gloria (Vivaldi)

Antonio Vivaldi wrote at least three settings of the hymn Gloria in excelsis Deo, whose words date probably from the 4th Century and which is an integral part of the Ordinary of the Mass. Two survive: RV 588 and RV 589. A third, RV 590, is mentioned only in the Kreuzherren catalogue and presumed lost. The RV 589 Gloria is a familiar and popular piece among sacred works by Vivaldi. It was probably written at about the same time as the RV 588, possibly in 1715.

As with other choral pieces the composer, Vivaldi, wrote many introduzione (introductory motets) that were to be performed before the Gloria itself. Four introduzioni exist for these Glorias: Cur Sagittas (RV 637), Jubilate, o amoeni cori (RV 639) (the last movement of which is compositionally tied with the first movement of RV 588), Longe Mala, Umbrae, Terrores (RV 640), and Ostro Picta (RV 642).

The lesser known of the two surviving Glorias, RV 588 was most likely composed during Vivaldi's employment at the Pio Ospedale della Pietà, known for its advanced choral ensemble. The first movement is interwoven with the last aria of RV 639, as explained above. The date of composition between this Gloria and RV 589 is still disputed, but both show compositional inspiration from each other.

RV 588 borrows extensively from a double orchestra-and-choir setting of the same text by Giovanni Maria Ruggieri (which will henceforth in this article be referred by its RV cataloguing number of RV. Anh. 23). Many movements show inspiration from this composition, and two movements ("Qui Tollis" and "Cum Sancto Spiritu") are plagiarised from the original Ruggieri setting (although "Qui Tollis" completely omits the second coro (chorus), and "Cum Sancto Spiritu" is slightly modified). The first movement of RV 588 is also an extended version of RV Anh. 23, sans the second coro employed in RV Anh. 23, among other musical modifications. The second movements of both RV 588 and RV 589 ("Et in Terra Pax") both show chromatic patterns and key modulations similar to that of the second movement of RV Anh. 23.

This is the better known setting of the Gloria, simply known as the Vivaldi "Gloria" due to its outstanding popularity. This piece, along with its mother composition RV 588, was composed at the same time during Vivaldi's employment at the Pieta. Two introduzioni exist as explained in the aforementioned article.

As in RV 588, there exists evidence of influence by RV Anh. 23: the first movement's chorus shares similar key modulations to that of the first movement of RV 588, only modified to fit a duple meter instead of the triple meter of RV 588. Motivic material present in the orchestral parts of either piece are also shared, including octave jumps in the opening motives of the piece. The second movement is significantly more chromatic in RV 589, but nonetheless is texturally similar to the setting present in RV Anh. 23, with the use of repeating rhythmic figures underneath harmonic motion. The "Qui Tollis" movement of RV 589 is rhythmically similar to the first few measures of RV 588 (and ultimately RV Anh. 23). The last movement, "Cum Sancto Spiritu," is essentially an "updated" version of movement present in both RV Anh. 23 and RV 588, except extensively harmonically modified, becoming more chromatic than its predecessors, reflecting a maturity in Vivaldi's output and the emerging style of the late Italian Baroque.
