There is a new music journal out titled Journal of interdisciplinary music studies, and which seems to be freely available online. I was particularly pleased to read Richard Parncutt’s opening paper on the history and future of systematic musicology. While it has been overshadowed (and to some extent suppressed) by historical musicology for the last decade, there seems to be a growing interest for systematic musicology today.
However, as Parncutt argues, much of this research is carried out under other names and in other departments, e.g. music psychology, music cognition, music technology, etc. Placing music psychology in a psychology department is like historical musicology should be placed in a history department, and ethnomusicology in social anthropology. Parncutt argues that it is important that all of these disciplines should be considered musicology and gathered in musicology departments to avoid musicology from totally breaking apart.
