Abstract
This paper contrasts individual and collective listening to music, with particular regard to the expressive qualities of music. In the first half of the paper a general model of joint attention is introduced. According to this model, perceiving together modifies the intrinsic structure of the perceptual task, and encourages a convergence of responses to a greater or lesser degree. The model is then applied to music, looking first at the silent listening situation typical to the classical concert hall, and second the noisy listening situation typical to rock or jazz concerts.
