Déjà vu is a piece inspired by the mysticism of the déjà vu effect, and by Conlon Nancarrow's impossible music for player piano (pianola).
The piece explores the déjà vu effect by the presentation and transformation of several themes and sound events between the performers and the electronics through procedures such as cross synthesis, granular synthesis, frequency processing, echo, reverberation, panning, chorus, etc., and an especial effect from the extreme amplification of an audio silence period after the use of noise reduction, inspired by the theories on the silence by John cage and Luigi Nono.
Another important inspiration in the piece is Conlon Nacarrow's impossible music for pianola. Nancarrow was one of the first composers to use musical instruments as machines, making them play far beyond human performance ability. In Déjà vu a dialogue between the human quartet and the computer quartet is established, where the computer also explores the déjà vu effect with the use of previous motives adding a different transformation to the previous: An extremely high tempo with impossible melodies. All the solo melodies of the final part were composed using Nyquist algorithmic composition application.
The piece starts in a misterious and disonant mood which is later transformed into a rhythmic section. The material of the last part is presented with humor, and both human and computer end their competition in a collaboration to produce what is really important: Music.
Dedicated to Erberk, Laura, Annie and Cody with especial thanks.
