Chamber music played a substantial role in the renewal of Portuguese music that took place during the 20th century. Freitas Branco’s kaleidoscopic Trio has an experimental feel, brimming with his typical rhythmic fluidity and sweeping melodic style, while Frederico de Freitas’s Prelúdio, coral e fuga is both colourful and technically impressive. Braga Santos’s infectious lyricism is evident in his Trio, and the origins of Delgado’s Trio Camoniano as a sequence of songs connects the worlds of classical music and fado.
