Antonio Vivaldi's Stabat Mater (RV 621) is a sacred work for alto solo, strings, and basso continuo, setting the medieval Latin poem Stabat Mater Dolorosa, which meditates on the suffering of the Virgin Mary during Jesus's crucifixion. Composed around 1712, it is a fine example of Vivaldi's early sacred vocal music, characterized by its expressive and somber mood, contrasting with the rhythmic vitality often found in his concertos.
