“…Along with providing a non-verbal, continuous means of response, some investigators have been able to control for musical training and stimulus properties in relationship to heightened affective experiences. For example, in several studies using high school through highly trained graduate level and professional musicians, the vast majority reported peak aesthetic experiences in response to an audio excerpt of Giacomo Puccini’s opera La Bohème (Byrnes, 1997; Madsen, 1997; Madsen et al, 1993; Madsen & Geringer, 2008; Napoles & Madsen, 2008; Southall, 2003). Additionally, some of the studies employed a mixed methodological design in order to investigate a number of additional variables, including the overall length, frequency, magnitude, and phenomenological properties of responses.…”
