Sociomusicology (from Latin: socius, "companion"; from Old French musique; and the suffix -ology, "the study of", from Old Greek λόγος, lógos : "discourse"), also called music sociology or the sociology of music, refers to both an academic subfield of sociology that is concerned with music (often in combination with other arts), as well as a subfield of musicology that focuses on social aspects of musical behavior and the role of music in society.
The work of scholars in sociomusicology is often similar to ethnomusicology in terms of its exploration of the sociocultural context of music; however, sociomusicology maintains less of an emphasis on ethnic and national identity and is not limited to ethnographic methods. Rather, sociomusicologists use a wide range of research methods and take a strong interest in observable behavior and musical interactions within the constraints of social structure. Sociomusicologists are more likely than ethnomusicologists to make use of surveys and economic data, for example, and tend to focus on musical practices in contemporary industrialized societies. For instance, proposed the hypothesis of "Biliterate and Trimusical" in Hong Kong sociomusicology.
Since the field of musicology has tended to emphasize historiographic and analytical/critical rather than sociological approaches to research, sociomusicology is still regarded as somewhat outside the mainstream of musicology. Yet, with the increased popularity of ethnomusicology in recent decades (with which the field shares many similarities), as well as the development and mainstreaming of "New Musicology" (coinciding with the emergence of interdisciplinary cultural studies in academia), sociomusicology is increasingly coming into its own as a fully established field. The values and meanings associated with music are collectively constructed by both music listeners and performers. When listening to a piece, they reflect upon their own values and use the music to make connections between their own experiences and what the piece is perceived as communicating.
