Sebastián de Vivanco, born around 1551 in Ávila and passing away in 1622 in Salamanca, was a Spanish priest and composer of the Renaissance period. His works, primarily choral, offer a glimpse into the sacred music of the Spanish Golden Age. Vivanco's compositions, such as his Requiem and the motets in "Sancti et Justi," showcase his mastery of polyphony and his significant contribution to Renaissance music. His pieces, like "Versa est in luctum," continue to captivate audiences with their rich harmonies and profound spiritual depth, making him a notable figure in the history of sacred choral music.
