“…We do not suggest that listener engagement ceases or decreases at the musical climax, but rather that the specific nature of engagement at this point is not evident or indexed by ISC. Recent work by Chabin et al (2020) has used EEG oscillatory band power to identify neural correlates of chills and emotional pleasure during natural music listening, while Czepiel et al (2020) linked ISC of physiological responses to live music to musical elements such as structural segmentation boundaries. Thus, future work could consider using EEG-ISC alongside complementary analysis approaches and response modalities to more fully characterize listener experiences of music.…”

Musical engagement can be conceptualized through various activities, modes of listening, and listener states - among these a state of focused engagement. Recent research has reported that this state can be indexed by the inter-subject correlation (ISC) of EEG responses to a shared naturalistic stimulus. While statistically significant ISC has been reported during music listening, these reports have considered only correlations computed across entire excerpts and do not provide insights into time-varying engagement. Here we present the first EEG-ISC investigation of time-varying engagement within a musical work. From a sample of 23 adult musicians who listened to a cello concerto movement, we find varying levels of ISC throughout the excerpt. In particular, significant ISC is observed during periods of musical tension that build to climactic highpoints, but not at the highpoints themselves. In addition, we find that a control stimulus retaining low-frequency envelope characteristics of the intact music, but little other temporal structure, also elicits significant neural correlation, though to a lesser extent than the original. In all, our findings shed light on temporal dynamics of listener engagement during music listening, establish connections between salient musical events and EEG-ISC, and clarify specific listener states that are indexed by this measure.

“…Ratings of excitement were associated with similar respiratory phases indicating a synchronization effect. In using synchrony as a measure of reliable stimulus-evoked physiological responses, synchronized respiration and skin conductance responses were more probable during faster music, and occurred during phrase repetitions, transitions and structural boundaries in a concert setting (Czepiel et al, 2020). Interbrain coherence, that is, neural synchronization , was found between a violinist and listeners using near-infrared spectroscopy in a laboratory setting (Hou et al, 2020).…”

Entrainment and synchronization play major roles in understanding the emotional effects of music; thus, we were interested in synchronized responses of concert audiences listening to music. A series of three separate public live concerts of the same three pieces (chamber music by Ludwig van Beethoven, Brett Dean, Johannes Brahms) was organized. Based on the notion that aesthetic experiences are embodied, we recorded the physiological signals (heart rate, respiration rate, skin conductance response) of all audience members of the concerts. We expected that the shared musical stimuli would entrain the physiological processes of listeners, which would become synchronized. Such synchrony was assumed to indicate the level of immersion in the music, a part of aesthetic experience, and hence be associated with self-report of music appreciation. Physiological signals of a sample of 99 participants were aggregated per bar of the music. Physiological synchrony was assessed using surrogate synchrony, an established method based on cross-correlations. Surrogate synchrony was applied to all dyads of listeners of each concert. Self-report information was provided by listeners after each piece (scales: Appreciation and Connectedness/ Empathizing) and after the concert (scales: Appreciation, Timing, and Inconvenience of Measurements). We found significant audience synchronies in most music pieces. Across the pieces, skin conductance synchrony and respiration rate synchrony were associated with self-reported appreciation. Assessments of inconvenience due to the measurement devices was linked with lowered respiration rate synchrony. We concluded that the approach of audience synchrony constitutes a step toward an objective methodology by which aesthetic experiences of concert audiences can be explored.

“…This proneness to become a hit could potentially be estimated by neural similarity measures. As several studies have already indicated that neural synchronization increased with specific aspects of music, such as rhythm, melody, tempo, and phrase repetitions ( Czepiel et al, 2020 ; Kaneshiro et al, 2020 ), it is agreed that neural similarity identifies emotions at the level of musical features and we hypothesize it will therefore serve as a strong predictor of mega-hit potential.…”

“…The subjective experience of music was found to relate to neural synchrony in the affective processing circuit ( Sachs et al, 2020 ), and Kaneshiro et al (2020) showed that basic musical features, such as rhythm and melody, elicited significantly higher neural correlation compared to scrambled musical samples. Additionally, Czepiel et al (2020) calculated the ISC during three live concerts and showed that tempo was consistently related to increased neural synchrony as well as phrase repetitions, transitional passages, and boundaries.…”

Neuroforecasting predicts population-wide choices based on neural data of individuals and can be used, for example, in neuromarketing to estimate campaign successes. To deliver true value, the brain activity metrics should deliver predictive value above and beyond traditional stated preferences. Evidence from movie trailer research has proposed neural synchrony, which compares the similarity of brain responses across participants and has shown to be a promising tool in neuroforecasting for movie popularity. The music industry might also benefit from these increasingly accurate success predictors, but only one study has been forecasting music popularity, using functional magnetic resonance imaging measures. Current research validates the strength of neural synchrony as a predictive measure for popularity of music, making use of electroencephalogram to capture moment-to-moment neural similarity between respondents while they listen to music. Neural synchrony is demonstrated to be a significant predictor for public appreciation on Spotify 3 weeks and 10 months after the release of the albums, especially when combined with the release of a single. On an individual level, other brain measures were shown to relate to individual subjective likeability ratings, including Frontal Alpha Asymmetry and engagement when combined with the factors artist and single release. Our results show the predictive value of brain activity measures outperforms stated preferences. Especially, neural synchrony carries high predictive value for the popularity on Spotify, providing the music industry with an essential asset for efficient decision making and investments, in addition to other practical implications that include neuromarketing and advertising industries.
