Mind the gap: The mediating role of emotion mechanisms in social bonding through musical activities.

I support the music and social bonding (MSB) framework, but submit that the authors' predictions lack discriminative power, and that they do not engage sufficiently with the emotion mechanisms that mediate between musical features and social bonding. I elaborate on how various mechanisms may contribute, in unique ways, to social bonding at various levels to help account for the socio-emotional effects of music.
