Tata Vasco is an opera in five scenes composed by Miguel Bernal Jiménez to a Spanish libretto with nationalistic and devoutly Roman Catholic themes by the Mexican priest and poet, Manuel Muñoz. It premiered in Pátzcuaro, Mexico on 15 February 1941. The opera is based on the life of Vasco de Quiroga, the first Bishop of Michoacán and known to the indigenous Purépecha of the region as 'Tata Vasco'. Considered one of Bernal Jiménez's most emblematic scores,[1] the music incorporates native melodies, dances, and instruments as well as elements of Gregorian chant.
