Officium Ensemble has established itself as one of Portugal’s most prominent vocal groups devoted to early music. The purity of its distinctive sound stems from the ensemble’s sustained work on blend, vocal production, and balance, developed since its foundation under the direction of Pedro Teixeira. Combined with this defining quality, the singers’ commitment and expressive intensity have earned Officium Ensemble wide acclaim for performances of striking impact and consistency, in which responsiveness to the text plays a central role.

Officium Ensemble brings together solid interpretative practice with ongoing musicological research, drawing on period prints and manuscripts in order to offer historically informed performances, while also enabling audiences to encounter first modern performances of a number of works. 

The ensemble’s core repertoire and area of specialisation span the entire Renaissance and the early Baroque period, with particular emphasis on Portuguese early music—specifically the music of the Cathedral of Évora—while also embracing the Franco-Flemish, Spanish, and English Tudor traditions.

The ensemble has performed at numerous venues and early music festivals, including the International Early Music Courses of the Évora Cathedral School of Music, the São Roque Music Festival, Terras sem Sombra Festival, Dias da Música (CCB), the Lisbon Organ Festival, the Úbeda y Baeza Early Music Festival (Spain), the International Festival of Sacred Art (Spain), the Granada International Festival of Music and Dance (Spain), AMUZ Laus Polyphoniae Festival (Belgium), and the Utrecht Early Music Festival Oude Muziek (Netherlands).
