Multidimensional representation of electroacoustic music

Abstract A five‐layered system of graphical representation has been created for the analysis of electroacoustic compositions. Electronic music often contains spectral changes and other timbral aspects that make traditional music notation inadequate. The sonogram is a useful representation of the frequency spectra and their evolutions. Additional layers have been included to clarify various aspects such as pitch relationships, phrasing, overall dynamic levels and processing techniques. Pitch notation, a phrase analysis, amplitude lines and a text line of comments have been combined to form more accurate visual representations of music.
