Musicology (from Greek 'μουσική' (mousikē) for 'music' and 'λογος' (logos) for 'domain of study') is the scholarly analysis and research-based study of music. Musicology departments traditionally belong to the humanities, although music research is often more scientific in focus (psychological, sociological, acoustical, neurological, computational). A scholar who participates in musical research is a musicologist.

Musicology departments traditionally belong to the humanities, although music research is often more scientific in focus (psychological, sociological, acoustical, neurological, computational). A scholar who participates in musical research is a musicologist. Musicology traditionally is divided in three main branches: historical musicology, systematic musicology and ethnomusicology. Ethnomusicology is the study of music in its cultural context. Systematic musicology includes music theory, aesthetics, pedagogy, musical acoustics, the science and technology of musical instruments, and the musical implications of physiology, psychology, sociology, philosophy and computing. Cognitive musicology is the set of phenomena surrounding the cognitive modeling of music. When musicologists carry out research using computers, their research often falls under the field of computational musicology. Music therapy is a specialized form of applied musicology which is sometimes considered more closely affiliated with health fields, and other times regarded as part of musicology proper. The 19th century philosophical trends that led to the re-establishment of formal musicology education in German and Austrian universities had combined methods of systematization with evolution. These models were established not only in the field of physical anthropology, but also cultural anthropology. This was influenced by Hegel's ideas on ordering 'phenomena' from the simple to complex as the stages of evolution are classified from primitive to developed, and stages of history from ancient to modern. Comparative methods became more widespread in diverse disciplines from anatomy to Indo-European linguistics, and beginning around 1880, also in comparative musicology.
