A color which unbends the rainbow





Mixed music, Piano, Supercollider, Golden rate, Mouse writing


Having approximately 6’30” of length this piece was written in 2017 for piano and electronics. It has golden rate – and its ramifications like Fibonacci sequence – as an inspiration to organize harmony and form. Piano assumes a solo character and the electronics – operated by two performers in two PCs – mixes fixed sounds (written in Portuguese on the score) and live electronics synthesis generated by the SuperCollider software (these ones written in English) in both computers. Fixed sounds (birds, airplane, rain etc.) are mixed in real time by both electronic performers via a mixer while live electronics (synthesis) are controlled by computer mouse and also sent to the mixer. Piano elements are treated like “sound objects” which become denser, little by little, until reach two climaxes pre-established by the Fibonacci sequence.
