Spectral music

A spectrogram of a violin playing a note and then a perfect fifth above it with the shared partials highlighted by the white dashes (harmonic spectra)
Harmonic spectrum (containing only harmonic overtones)

Spectral music uses the acoustic properties of sound – or sound spectra – as a basis for composition.[1]
