A musicologist is someone who studies music (see musicology). A historical musicologist studies music from a historical perspective. An ethnomusicologist studies music from the perspective of different world cultures (see ethnomusicology). A systematic musicologist asks general questions about music from the perspective of relevant disciplines (psychology, sociology, acoustics, philosophy, physiology, computer science) (see systematic musicology). Systematic musicologists often identify more strongly with their non-musical discipline than with musicology.
