Explanation:

Systematic musicology has traditionally been conceived as an interdisciplinary science, whose objective is to explore the foundations of music from different points of view, such as acoustics, physiology, psychology, anthropology, music theory, sociology and aesthetics.

 Systematic musicology is different in that it tends not to put these specific manifestations in the foreground, although of course it refers to them. Instead, the most general questions about music are raised.

Since systematic musicology brings together several parent disciplines, it is often considered as intrinsically interdisciplinary, or as a system of interacting subdisciplines.
