Pomàrico, Emilio

Spectralism is a movement in contemporary classical music that treats timbre and the acoustic spectrum as primary compositional materials. Rather than building music from abstract pitch-class sets or functional harmony, spectral composers derive harmonies, orchestrations, and formal processes from the real-world spectra of sounds. Using tools such as Fourier analysis, they decompose a sound into its partials and then re-synthesize or orchestrate those partials across instruments, often employing microtonality, extended techniques, and slow, morphing processes. The result is music where color, resonance, and perceptual phenomena shape structure as much as melody or rhythm.
