From 1984 to 1987, with a scholarship from the Calouste Gulbenkian Foundation of Lisbon, Chagas Rosa studied Contemporary Piano and Chamber Music with Alexander Hrisanide at the Sweelinck Conservatory in Amsterdam. Between 1987 and 1992, with a scholarship granted by the Portuguese government, he studied composition at the Rotterdams Conservatory under Klaas de Vries and Peter Jan Wagemans.
In The Netherlands, António Chagas Rosa worked as a repetiteur and assistant at the Dutch opera house, Het Muziektheater, and became a teacher of the opera class at the Sweelinck Conservatorium.

As a pianist he took part in many of the concerts organized by the Gaudeamus and "The Unanswered Question" foundations. In 1989, being invited by the dance group Dansproductie of Amsterdam, he performed music by John Cage for prepared piano in many Dutch cities as well as in London, Mulhouse and Gent.
In 1994, the Acarte department of the Calouste Gulbenkian Foundation commissioned him with the composition of the chamber opera "Canticles for the remission of hunger", upon a libretto by the Portuguese writer Paulo Lages. Further commissions were provided by the International Music Festival of Macau, the Portuguese Radio (Antena 2), the Teatro Nacional de São Carlos in Lisbon, the Casa de Mateus Foundation, the Nederlands Kamerkoor, and many others.
His works have been performed in several modern music festivals in Portugal, Spain, France, Holland, Austria, Germany, Sweden, Switzerland, Ukraine, the U.S.A., Macau and Hong-Kong, etc. In 1997 he represented Portugal in the Tribune Intérnationale des Compositeurs (UNESCO) in Paris with his concerto for piano and orchestra. During the 1998 edition of Wien Modern , the Austrian ensemble Klangforum premiered Moh (commissioned by the Portuguese festival Music in November); this piece was also performed in Spain (Ensems, Valencia) and Portugal ( Serralves hall, in Porto) by the Remix Ensemble, with Stefan Asbury as conductor.

António Chagas Rosa’s latest opera — Melodias Estranhas — upon a libreto by the Dutch writer Gerrit Komrij, was the result of a joint commission made by the cities of Oporto and Rotterdam, European Capital of Culture in 2001. It tells three episodes of the life of the 16th century humanist philosopher Damião de Góis, student and friend of Erasmus of Rotterdam. Also a composer, he was accused by the Inquisition of writing inappropriate (polyfonic) music, imprisioned and later killed. The premiere of this opera took place at the Schouwburg of Rotterdam, as a joint production of Casa da Música (Oporto) and the Onafhankelijk Toneel of Rotterdam.
