“…This question has attracted research with a focus on acoustic/perceptual features that include: sound intensity/loudness (Chapin, Large, Jantzen, Kelso, & Steinberg, 2008;Olsen, Stevens, & Tardieu, 2007); frequency/pitch and tonality (Kessler, Hansen, & Shepard, 1984;Windsor, 1997); sound duration/meter and tempo (Boltz, 1998;Chapin, et al, 2008;Quinn & Watt, 2006;Todd, Cousins, & Lee, 2007;Vuust, Ostergaard, Pallesen, Bailey, & Roepstorff, 2009); and spectrum/timbre (Bailes & Dean, 2007;Caclin, McAdams, Smith, & Winsberg, 2005;Gordon & Grey, 1978), as these relate to perceived structure and emotional response (Bailes & Dean, 2009;Bigand, Vieillard, Madurell, Marozeau, & Dacquet, 2005;Dubnov, McAdams, & Reynolds, 2006;Gabrielsson & Lindstrom, 2001;Leman, Vermeulen, De Voogdt, Moelants, & Lesaffre, 2005;Schubert, 2004;Sloboda, 1991;Sloboda & Lehmann, 2001). An issue in this work is the inadequacy of treating music as a static entity, since perception is determined by the temporal organization of these acoustic properties (Brittin & Duke, 1997;Deliège, Mélen, Stammers, & Cross, 1996;Krumhansl & Kessler, 1982;Lalitte & Bigand, 2006;McAdams, Vines, Vieillard, Smith, & Reynolds, 2004;Schubert, 2004;Sloboda & Lehmann, 2001). This paper will detail an analytical method allowing for just such a dynamic examination of the relationship between acoustical properties of a composition with real-time listener perceptions of its structure and its affective content.…”
