Spectral music is an avant-garde genre that emphasizes the analysis and manipulation of the overtone spectrum—focusing on the acoustic properties of sound itself rather than traditional harmonic or melodic development. Emerging in the late 20th century, it uses advanced techniques such as Fourier analysis and microtonality to derive compositional material from the inner workings of sound. The genre often results in immersive, evolving textures that highlight timbre and resonance over rhythm or narrative form. Ensembles and composers in this realm explore complex sonorities and extended instrumental techniques, crafting soundscapes that are both abstract and deeply rooted in natural acoustics.
