Cartas Celestes (Celestial Charts) is one of prolific Brazilian composer José Antônio Rezende de Almeida Prado’s most important achievements. Exploring every kind of resonance and sound the piano has to offer and using a new harmonic language called “transtonality”, this set of works is described by pianist Aleyson Scopel as “a heroically audacious cycle” that depicts the sky and constellations in “colours, light, darkness and an almost mythological understanding and approach to the universe”.
