Music tonality and context-dependent recall: The influence of key change and mood mediation

Abstract

Music in a minor key is often claimed to sound sad, whereas music in a major key is typically viewed as sounding cheerful. Such claims suggest that maintaining or switching the tonality of a musical selection between information encoding and retrieval should promote robust “mood-mediated” context-dependent memory (CDM) effects. The reported experiment examined this hypothesis using versions of a Chopin waltz where the key was either reinstated or switched at retrieval, so producing minor–minor, major–major, minor–major, and major–minor conditions. Better word recall arose in reinstated-key conditions (particularly for the minor–minor group) than in switched-key conditions, supporting the existence of tonality-based CDM effects. The tonalities also induced different mood states. The minor key induced a more negative mood than the major key, and participants in switched-key conditions demonstrated switched moods between learning and recall. Despite the association between music tonality and mood, a path analysis failed to reveal a reliable mood-mediation effect. We discuss why mood-mediated CDM may have failed to emerge in this study, whilst also acknowledging that an alternative “mental-context” account can explain our results (i.e., the mental representation of music tonality may act as a contextual cue that elicits information retrieval).

We would like to thank David Ridout for his expert assistance in both transposing and playing the piano music used in this study. We are grateful to Karl-Heinz Bäuml, Eric Eich, Johanna Kissler and an anonymous reviewer for valuable comments on a previous version of this paper.
