Integration of methods is an option for interdisciplinary research settings, allowing insights into the fleeting moments of aesthetic experience. This chapter aims to exemplify such research settings by introducing two research projects: eMotion: MappingMuseum Experience and ECR—Experimental Concert Research. eMotion concerned aesthetic experiences in the environment of a fine arts museum, and ECR investigates music experience in concerts. Both projects were conducted in ecologically valid environments: the fine art museum and the classical concert hall, respectively. The technical setup of both projects merged different data levels—body movement, heart rate, skin conductance, facial expressions, sociological variables, and emotional and aesthetic evaluations of specific artworks or musical pieces—into an integrated dataset. In both projects, scientists (from musicology, art history, psychology, cultural studies, etc.), technicians, and programmers, as well as practitioners like artists, musicians, and curators, were brought together to intensively cooperate. The chapter elaborates on the aspects of such inter- and transdisciplinary research endeavors.
