Organology (from Ancient Greek ὄργανον (organon) 'instrument' and λόγος (logos), 'the study of') is the science of musical instruments and their classifications.[1] It embraces study of instruments' history, instruments used in different cultures, technical aspects of how instruments produce sound, and musical instrument classification. There is a degree of overlap between organology, ethnomusicology (being subsets of musicology) and the branch of the science of acoustics devoted to musical instruments.
