Temporal Gestalt qualities, on the other hand, are generated by “every change of any kind in a presentational complex, providing it proceeds in some definite direction”, specifically, if such change “reveals a unified character, so that we have (or could have) a name to designate it” (Ehrenfels 1890; Smith 1988, 97 ff.), it identifies a Gestalt quality. However, not only change, but also persistence, such as the sustaining of a note, can give rise to a peculiar Gestalt quality (Ehrenfels 1890; Smith 1988, 101).
