In Koramachine two different sound systems are contrasted, an instrumental group and a violin electronically processed in real time with a ring modulator. The contrast between the two groups is not only of a timbral nature, but it is the very procedure of creating the sound that follows conceptually opposite criteria: the traditional instrumental group produces a timbre that is given by the sum of each individual instrument, while the
sound result of the modulated violin is given by progressive transformations of a single starting sound.
“Koramachine” was written in 1981 and is the first in a series of works for solo instrument with electronic processing created by the author. To this follow: “Incontro con Rama” for trombone, “Titanic & Icarus s.p.a.” for percussion and “Etaoin Shrdlu” for double bass.
These works were composed using the harmonic natural scale.
