Lùmina is a piece of electronic music made with acoustic instruments. In fact, it consist of two different concepts, each one recalling a particular approach to electronic music.
Sections 1, 3 and 5 draw inspiration from musique concrète, where the tape was cut into slices and recombined. Such sections examine the juxtaposition and superimposition of tape slices cut in different manners and filled with various materials, as well as fade in and out techniques.
Sections 2, 4 and 6 refer to sound synthesis (and analysis). They gradually cover the whole acoustic spectrum by means of partials calculated as harmonics shared by respectively two, three or four fundamentals, with an approximation of an eighth of a tone.
“Lùmina” is a Latin word which means “light”, but also “aperture”. In this metaphorical view of electronic music, aperture is the abrupt or smooth switching from one tape slice to another, or the slow opening of a lowpass filter which lets out more and more higher frequencies, thus letting the “light” (white noise) pass at last.
