Summary
Listeners abandon old musical keys abruptly but gradually accept new keys. Greater key change distances improve detection accuracy but require more adaptation time, impacting music cognition.
Area of Science:
- Music cognition
- Auditory perception
- Psychoacoustics
Background:
- Understanding music relies on processing key changes.
- The timing and mechanisms of musical key adjustment remain unclear.
Purpose of the Study:
- To investigate when and how listeners adjust to key changes in music.
- To explore the influence of key change distance and post-change interval on adaptation.
Main Methods:
- Three experiments using obscure melodies with manipulated key changes.
- Participants performed explicit change detection and probe tone rating tasks.
- Probe tone ratings were used to infer listeners' representations of musical keys.
Main Results:
- Listeners abruptly abandoned previously established keys.
- Adaptation to new keys occurred gradually.
- Larger key change distances (e.g., C to F#) led to more accurate change detection.
- More distant key changes required longer adaptation periods.
Conclusions:
- Musical key adjustment involves rapid abandonment of old keys and gradual acceptance of new ones.
- The magnitude of key change significantly impacts both detection and adaptation time.
- These findings shed light on the temporal dynamics of music perception and key representation.
