Salve Regina: RV 616The Salve Regina is the Marian antiphon prescribed for the period running from Trinity Sunday to the Saturday preceding the first Sunday in Advent. This antiphon has six sentences, which Vivaldi sets as six contrasting movements in RV .
Vivaldi wrote three settings for the Salve Regina. The Salve Regina RV 616 is scored for alto, most probably for a female, and double orchestra which is laid out in two choirs. This setting requires the usual strings but also two recorders and a transverse flute in the first choir. The vocal writing has a great beauty to it and it does require some ornamentation.
The Latin text is as follows:
Salve, Regina, Mater misericordiæ,
vita, dulcedo, et spes nostra, salve.
Ad te clamamus exsules filii Hevæ.
Ad te suspiramus, gementes et flentes
in hac lacrimarum valle.
Eia, ergo, advocata nostra, illos tuos
misericordes oculos ad nos converte.
Et Jesum, benedictum fructum ventris tui,
nobis post hoc exsilium ostende.
O clemens, O pia, O dulcis Virgo Maria.
The following are the six versions that I have in my collection, interestingly four male and two female vocalists. The standard performance duration is around sixteen/seventeen minutes.
Scholl/Dyer: 
Scholl and Dyer deliver a fine performance. Scholl’s delivery is light but strong. The overall tone is devotional but when the Vivaldian moments are required Dyer delivers the requisite spirit and sense of vibrancy when called upon.
