Musicology also has two central, practically oriented sub-disciplines with no parent discipline: performance practice and research, and the theory, analysis and composition of music. The disciplinary neighbors of musicology address other forms of art, performance, ritual, and communication, including the history and theory of the visual and plastic arts and architecture; linguistics, literature and theater; religion and theology; and sport. Musical knowledge is applied within medicine, education and music therapy—which, effectively, are parent disciplines of applied musicology.
