Zusammenfassung We present the results of a study testing the often-theorized role of musical expectations in inducing listeners’ emotions in a live flute concert experiment with 50 participants. Using an audience response system developed for this purpose, we measured subjective experience and peripheral psychophysio- logical changes continuously. To confirm the existence of the link between expectation and emotion, we used a three-fold approach. (1) Based on an information-theoretic cognitive model, melodic pitch expectations are predicted by analyzing the musical stimuli used (six pieces of solo flute music). (2) A continuous rating scale was used by half of the audience to measure their experience of unexpect- edness towards the music heard. (3) Emotional reactions were measured using a multi-component approach: subjective feeling (valence and arousal rated continuously by the other half of the audience members), expressive behavior (facial EMG) and peripheral arousal (the latter two being measured on all 50 participants). Results confirmed the predicted relationship between high- information-content musical events, the violation of musical expectations (in corresponding ratings) and emotional reac- tions (psychologically and physiologically). Musical structures leading to expectation reactions were manifested in emotional reactions at different emotion component levels (subjective experience and autonomic nervous system activations). These results emphasize the role of musical structure in emo- tion induction, leading to a further understanding of the frequently experienced emotional effects of music.
