harmony--things sounding at the same time
Would you use that term to include non-pitched sounds occurring at the same time as well (or a combination of both)? Combinations of timbres (whether in an acoustic setting, e.g. through orchestration, or in electroacoustic works) seem very fundamental to music, especially in recent times; I wonder if there might be a better 'fundamental' term than harmony (which as I understand it privileges pitched sounds), which can encompass harmony itself and other types of sonic combination?
