Geralda with Tato Taborda (Rio/Brasil)
(built by Alexandre Boratto of AVLTech)Geralda is a multi-instrumental structure, an “one-man-band”, constructed
by the composer Tato Taborda and Alexandre Boratto. It’s origin was a
project supported by a grant from the Vitae Foundation, which included both
the construction of the instrument and the composition of Canções
de Musgo e Pó, inspired on writings of the brazilian poet Manoel de
Barros.
Since then, like a living being, Geralda has evolved under the influences of
the different projects that took part. In each new piece, instruments are added,
taken, processed, deconstructed, fragmented, in a dynamic process toward a
experimental territory that could be called “pointless technology”.
In fact, although the orchestra exists since 1993, it was just “baptized” in
2002, by a female friend who discovered that not just that instrument was a
female entity, Geralda, but that it was also pregnant. From this bombastic
revelation on, my interaction with the instrument dramatically changed, and
I turned to a more delicate and sweet stile of playing. As a result, a whole
different set of sonorities emerged. Sonorities that her old identity (or no
identity) had kept in secret, women’s secret.
In it’s present state, Geralda is equipped with approximately 70 different
sound sources, among acoustical, electro-acoustical and electronic sources,
comprising several species of formal and not formal wind, strings and percussion
instruments. All these sources are amplified and can be recorded in real time
by a loop generator developed by the swiss engineer Matthias Grob. Among these
instruments, an adapted old typewriting machine keyboard, in which each key
is connected to a different percussion instrument, a vertical acordeon controlled
by foot, a mechanic rhythmic machine that triggers several instruments in different
parts of the structure, in a mechanism that remind us that of the music box,
and a metallic plate suspended by coils in the roof of Geralda, that serves
as vibrating field for small circular metallic pieces, producing different
frequencies, buzzings and feedbacks. Besides, Geralda has it’s own
amplification and diffusion system, which allows her to move graciously with
the aid of wheels.
