Portuguese composer. Rebelo came to the attention of Dom João, later D. João [John] IV, when the future king was studying music in Vila Viçosa with Roberto Tomar (1587-1629) and Rebelo became a singer in the ducal chapel in 1624. With the death of D. Teodosio II in 1630, João became the eighth Duke of Braganca. Ten years later, he went on to free Portugal from the dominance of Spain and was proclaimed King. His passion for music is well known. he became an avid collector of manuscripts and prints - the surviving first part of the index to his Library indicates an impressive collection, including the names of many works that would otherwise have remained unknown. D. Joao IV was also a composer, though there are now doubts about some of the most popular pieces attributed to him. D. João brought Rebelo to the Lisbon court. Rebelo's music has survived in part due to a testamentary disposition of the King that led to publication in Rome of Psalmi tum vesperarum tum completarum, item Magnificat, Lamentaciones, para efectivos entre 4 e 14 vozes, most of the contents of which are works written between 1635 and 1653, including two motets by D. >João IV. Rebelo's works reflect an opulent compositional style reminiscent of Gabrieli and Moneteverdi
