“…Audiences can visually ascertain a performer's emotional intentions (Dahl & Friberg, 2007) and the relative size of sung intervals (Thompson & Russo, 2007), as well as extract certain structural and expressive aspects of a musical composition from an accompanying choreographed dance (Krumhansl & Schenck, 1997). Furthermore, vision can influence the perception of pitch (Gillespie, 1997;Thompson et al, 2005), loudness (Rosenblum & Fowler, 1991), and timbre (Saldaña & Rosenblum, 1993), as well as affect (Thompson, Russo, & Quinto, 2008), expressivity (Davidson, 1993(Davidson, , 1994, audience interest (Broughton & Stevens, 2009), phrasing (Vines, Krumhansl, Wanderley, & Levitin, 2006), performance quality (Wapnick, Darrow, Kovacs, & Dalrymple, 1997;Wapnick, Mazza, & Darrow, 1998), and lyric comprehension (Hidalgo-Barnes & Massaro, 2007). Because of the widespread nature of vision's role in music, a further understanding of the perceptual consequences of musicians' physical gestures will be useful to performers and audiences alike.…”
