This chapter offers a brief and necessarily incomplete overview of what has been written on the interdisciplinary arts within academic scholarship on the creative arts. The author identifies five major integrative aspects highlighted in the existing literature on the interdisciplinary arts: (1) the Wagnerian Gestamtkunstwerk, i.e., the `total work of art;’ (2) the legacy of the historical avant-garde, with its focus on radical juxtaposition; (3) the continuation of post WWII arts experimentation in between and among multiple art mediums simultaneously with Happenings, intermedia and multimedia; (4) the intersections between art, science, and/or technology; and (5) interdisciplinary arts as its own emergent subject of inquiry, practice, and research. The chapter additionally includes a brief overview of the transdisciplinary arts. It concludes with the observation that considerations of current developments in interdisciplinary arts will serve to advance the understanding of interdisciplinarity in general.
