 Philosophers have also done much to articulate the connection between imagination and engagement with music (see the entry on  philosophy of music;  see also Trivedi 2011). Some philosophers focus on commonalities between engagement with narratives and engagement with music. For example, even though Walton (1990, 1994a, 1999) acknowledges that fictional worlds of music are much more indeterminate than fictional worlds of narratives, he maintains that the same kind of imagining used in experiencing narratives is also used in experiencing various elements of music, such as imagining continuity between movements and imagining feeling musical tension. Similarly, Andrew Kania (2015) argues that experiencing musical space and movement is imaginative like our experience of fictional narratives. Other philosophers draw parallels between engagement with music and other imaginative activities, namely as understanding other minds  (section 3.1)  and interpreting metaphor  (section 3.7).  As an example of the former, Jerrold Levinson (1996) argues that the best explanation of musical expressiveness requires listeners to experience music imaginatively—specifically, imagining a persona expressing emotions through the music. As an example of the latter, Scruton (1997) argues that musical experience is informed by spatial concepts applied metaphorically, and so imaginative perception is necessary for musical understanding (but see Budd 2003 for a criticism; see also De Clercq 2007 and Kania 2015). Stephen Davies (2005, 2011) and Peter Kivy (2002) notably criticize the imaginative accounts of engagement with music on empirical and theoretical grounds.
