Theodoro Cyro de Souza was a Portuguese composer and organ player, born in Caldas da Rainha in 1761. He was admitted as a pupil of the See Seminar (Seminário da Sé Patriarcal
) in Lisbon when he was six years old. After his formative period (probably tutored by music masters such as Souza Carvalho, Leal Moreira and David Perez), he left Portugal in 1781 to become the Chapel Master at the See Cathedral in Salvador under the sponsorship of the King Dom Pedro, as was expected with this kind of job. His predecessor was one of the most outstanding Brazilian music theorists and Chapel Masters, Caetano de Melo de Jesus. Of his musical production, there are only twenty-one manuscripts located in countries such as Portugal, Brazil and Italy, all of them composed for voices and continuo. The work Ascendit Deus
(completed with a final Alleluia section), described by the author as a Motet for five concerted voices for the Tuesday of Ascension, clearly shows the dominant music-writing in Luso-Brazilian religious repertoire where counterpoint, simple canonic and fugato passages (mostly for two of the five voices) form a clear and balanced counterpart with homophonic sections. The expressive technique of this composer was not completely known until recent researches.
