Global matching in music familiarity: How musical features combine across memory traces to increase familiarity with the whole in which they are embedded

•Familiarizing isolated musical features increased subsequent familiarity for songs.•Separately encoded rhythm and pitch sequences increased familiarity additively.•Multiple exposures to a rhythm increased song familiarity additively.•An additivity principle was found in MINERVA 2's familiarity computations.•Music feature familiarization across traces exhibited MINERVA 2-type additivity.
