Music cognition researchers have proposed a relationship between the perception of unexpected harmonic events and preference in music. The brain strategies underlying this relationship, however, have not been substantially elucidated. Using "surprise", a quantitative measure of expectation violation from information theory, three hypotheses were tested. The first, the Absolute-Surprise Hypothesis, states that moderate increases in surprise inherently lead to preference. The second, the Contrastive-Surprise Hypothesis, states that passages of music including sections of moderately high surprise, followed by sections of lower surprise, lead to preference. Finally, support for both hypotheses above prompts a third: the Hybrid-Surprise Hypothesis. This hypothesis states that there are absolute and contrastive surprise effects that contribute to preference. Statistical analyses were performed on a corpus of Western popular music released from 1958-1991, examining absolute and contrastive surprise effects on preference. Measures of surprise were compared between the top quartile and bottom quartile of songs in the corpus by peak Billboard chart position. Surprise differences were tested to examine possible effects on preference. In the analyses for Chapter II, we used all the songs in the corpus to estimate the probability distribution of chords and from that, measures of surprise. Therefore, the analyses could not determine whether the results were similar regardless of time from 1958 to 1991. An analysis of time dependence of surprise effects on preference is presented in Chapter III. Next, a behavioral preference experiment was performed to test the validity of the statistical findings in Chapter II independently. The experiment featured musical stimuli based on computer-generated chord progressions, designed to vary in absolute and contrastive surprise, controlling for other factors. The results provided support for the Hybrid-Surprise Hypothesis. We also found that these surprise effects measurably increased over time from 1958 to 1991. Taken together, these results provide insight into the relationship between the perception of unexpected harmonic events and preference in music. Future electrophysiological and/or neuroimaging studies may be required to understand the underpinnings of the hybrid process in the brain. The analyses and experiments presented in this dissertation might serve as a foundation upon which such studies might be designed.
