Commissioned and dedicated to Roberto Oliveira. First performance was given by Roberto Oliveira in the 'Extravaganza Percussion Festival', at Royal Irish Academy of Music, Dublin, Ireland, February 14, 2016. The third movement, deciso, was recorded in the album "Diáspora", released in 2017 by Roberto Oliveira.
A hologram is obtained by superimposing a second wavefront (normally called the 'reference beam') on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest.
With this idea in mind, I set out to design a work in which the fixed electronics would interacting not only as an overlay of sonic elements, but also as the 'double', somewhat 'doppelgänger', of the soloist acoustic instrument; so that listeners would not be able to clearly perceive which sounds come from which particular source. To reinforce this ambiguity, the acoustic vibraphone is manipulated both analogically and virtually, firstly, by the use of exogenous elements to the instrument itself (e.g. objects of any kind of materials, a trombone plunger mute, extended techniques, etc.); and secondly, by 'filtering' the acoustic sound through a set of effect pedals like those used by electric guitars. The final result is that of a multi-stylistic work which spans about 20 minutes of length, with the ambiguity as the unifying element of the three movements that form it, being: the timbral ambiguity, the formal ambiguity and the rhythmic ambiguity developed respectively.
