Officium Ensemble has established itself as one of the most prominent Portuguese vocal ensembles dedicated to early music. Since its foundation by director Pedro Teixeira, the ensemble has achieved a noted purity of sound; a result of the group’s constant striving for balance, blending, and pure vocal emission. The commitment and expressiveness of this select group of 12 singers has lead Officium Ensemble’s performances to be acclaimed for their vivacity, expressive contour, and responsiveness to the text. The core repertoire of Officium Ensemble ranges from Renaissance music to the Early Baroque. Music of the Portuguese, Spanish, Franco-Flemish and English Schools is performed, whilst special attention is placed on early music of Portugal and, more specifically to the music of Évora Cathedral. The ensemble has performed in numerous early music venues and festivals, from the International Days of the Évora School of Music and Festival Música em São Roque, to the festivals Terras sem Sombra, Dias da Música (CCB), Festival de Órgão de Lisboa , Marvão and Cistermúsica International Music Festival (Alcobaça). Since a few years ago, Officium Ensemble has been a regular presence in important international early music festivals, such as the Festival AMUZ Laus Polyphoniae, in Antwerp, and the Festival of Early Music in Utrecht – Oude Muziek.
