The parsing of undifferentiated tone sequences into groups of qualitatively distinct elements is one of the earliest rhythmic phenomena to have been investigated experimentally ( Bolton, 1894 ). The present study aimed to replicate and extend these findings through online experimentation using a spontaneous grouping paradigm with forced-choice response (from 1 to 12 tones per group). Two types of isochronous sequences were used: equitone sequences, which varied only with respect to signal rate (200, 550, or 950 ms interonset intervals), and accented sequences, in which accents were added every two or three tones to test the effect of induced grouping (duple vs. triple) and accent type (intensity, duration, or pitch). In equitone sequences, participants’ grouping percepts ( N = 4,194) were asymmetrical and tempo-dependent, with “no grouping” and groups of four being most frequently reported. In accented sequences, slower rate, induced triple grouping, and intensity accents correlated with increases in group length. Furthermore, the probability of observing a mixed metric type—that is, grouping percepts divisible by both two and three (6 and 12)—was found to be highest in faster sequences with induced triple grouping. These findings suggest that lower-level triple grouping gives rise to binary grouping percepts at higher metrical levels.

Music often triggers a pleasurable urge in listeners to move their bodies in response to the rhythm. In music psychology, this experience is commonly referred to as groove . This study presents the Experience of Groove Questionnaire , a newly developed self-report questionnaire that enables respondents to subjectively assess how strongly they feel an urge to move and pleasure while listening to music. The development of the questionnaire was carried out in several stages: candidate questionnaire items were generated on the basis of the groove literature, and their suitability was judged by fifteen groove and rhythm research experts. Two listening experiments were carried out in order to reduce the number of items, to validate the instrument, and to estimate its reliability. The final questionnaire consists of two scales with three items each that reliably measure respondents’ urge to move (Cronbach’s α = .92) and their experience of pleasure ( α = .97) while listening to music. The two scales are highly correlated ( r = .80), which indicates a strong association between motor and emotional responses to music. The scales of the Experience of Groove Questionnaire can independently be applied in groove research and in a variety of other research contexts in which listeners’ subjective experience of music-induced movement and enjoyment need to be addressed: for example the study of the interaction between music and motivation in sports and research on therapeutic applications of music in people with neurological movement disorders.

In studies of perceptual and neural processing differences between musicians and nonmusicians, participants are typically dichotomized on the basis of personal report of musical experience. The present study relates self-reported musical experience and objectively measured musical aptitude to a skill that is important in music perception: temporal resolution (or acuity). The Advanced Measures of Music Audiation (AMMA) test was used to objectively assess participant musical aptitude, and adaptive psychophysical measurements were obtained to assess temporal resolution on two tasks: within-channel gap detection and across-channel gap detection. Results suggest that musical aptitude measured with the AMMA and self-reporting of music experiences (duration of music instruction) are both related to temporal resolution ability in musicians. The relationship between musical aptitude and/or duration of music training is important to music educators advocating for the benefits of music programs as well as in behavioral and neurophysiological research.

This study reports on an experiment that tested whether drummers systematically manipulated not only onset but also duration and/or intensity of strokes in order to achieve different timing styles. Twenty-two professional drummers performed two patterns (a simple “back-beat” and a complex variation) on a drum kit (hi-hat, snare, kick) in three different timing styles (laid-back, pushed, on-beat), in tandem with two timing references (metronome and instrumental backing track). As expected, onset location corresponded to the instructed timing styles for all instruments. The instrumental reference led to more pronounced timing profiles than the metronome (pushed strokes earlier, laid-back strokes later). Also, overall the metronome reference led to earlier mean onsets than the instrumental reference, possibly related to the “negative mean asynchrony” phenomenon. Regarding sound, results revealed systematic differences across participants in the duration (snare) and intensity (snare and hi-hat) of strokes played using the different timing styles. Pattern also had an impact: drummers generally played the rhythmically more complex pattern 2 louder than the simpler pattern 1 (snare and kick). Overall, our results lend further evidence to the hypothesis that both temporal and sound-related features contribute to the indication of the timing of a rhythmic event in groove-based performance.

Consonance and dissonance are basic phenomena in the perception of chords that can be discriminated very early in sensory processing. Musical expertise has been shown to facilitate neural processing of various musical stimuli, but it is unclear whether this applies to detecting consonance and dissonance. Our study aimed to determine if sensitivity to increasing levels of dissonance differs between musicians and nonmusicians, using a combination of neural (electroencephalographic mismatch negativity, MMN) and behavioral measurements (conscious discrimination). Furthermore, we wanted to see if focusing attention to the sounds modulated the neural processing. We used chords comprised of either highly consonant or highly dissonant intervals and further manipulated the degree of dissonance to create two levels of dissonant chords. Both groups discriminated dissonant chords from consonant ones neurally and behaviorally. The magnitude of the MMN differed only marginally between the more dissonant and the less dissonant chords. The musicians outperformed the nonmusicians in the behavioral task. As the dissonant chords elicited MMN responses for both groups, sensory dissonance seems to be discriminated in an early sensory level, irrespective of musical expertise, and the facilitating effects of musicianship for this discrimination may arise in later stages of auditory processing, appearing only in the behavioral auditory task.

Sonata and rondo movements are often defined in terms of large-scale form, yet in the classical era, rondos were also identified according to their lively, cheerful character. We hypothesized that sonatas and rondos could be categorized based on stylistic features, and that rondos would involve more acoustic cues for happiness (e.g., higher average pitch height and higher average attack rate). In a corpus analysis, we examined paired movement openings from 180 instrumental works, composed between 1770 and 1799. Rondos had significantly higher pitch height and attack rate, as predicted, and there were also significant differences related to dynamics, meter, and cadences. We then conducted an experiment involving participants with at least 5 years of formal music training or less than 6 months of formal music training. Participants listened to 120 15-second audio clips, taken from the beginnings of movements in our corpus. After a training phase, they attempted to categorize the excerpts (2AFC task). D-prime scores were significantly higher than chance levels for both groups, and in post-experiment questionnaires, participants without music training reported that rondos sounded happier than sonatas. Overall, these results suggest that classical formal types have distinct stylistic and affective conventions.

The study of music-evoked autobiographical memories (MEAMs) has grown substantially in recent years. Prior work has used various methods to compare MEAMs to memories evoked by other cues (e.g., images, words). Here, we sought to identify which methods could distinguish between MEAMs and picture-evoked memories. Participants ( N = 18) listened to popular music and viewed pictures of famous persons, and described any autobiographical memories evoked by the stimuli. Memories were scored using the Autobiographical Interview (AI; Levine, Svoboda, Hay, Winocur, & Moscovitch, 2002 ), Linguistic Inquiry and Word Count (LIWC; Pennebaker et al., 2015 ), and Evaluative Lexicon (EL; Rocklage & Fazio, 2018 ). We trained three logistic regression models (one for each scoring method) to differentiate between memories evoked by music and faces. Models trained on LIWC and AI data exhibited significantly above chance accuracy when classifying whether a memory was evoked by a face or a song. The EL, which focuses on the affective nature of a text, failed to predict whether memories were evoked by music or faces. This demonstrates that various memory scoring techniques provide complementary information about cued autobiographical memories, and suggests that MEAMs differ from memories evoked by pictures in some aspects (e.g., perceptual and episodic content) but not others (e.g., emotional content).

In an experimental study, we investigated how well novices can learn from each other in situations of technology-aided musical skill acquisition, comparing joint and solo learning, and learning through imitation, synchronization, and turn-taking. Fifty-four participants became familiar, either solo or in pairs, with three short musical melodies and then individually performed each from memory. Each melody was learned in a different way: participants from the solo group were asked via an instructional video to: 1) play in synchrony with the video, 2) take turns with the video, or 3) imitate the video. Participants from the duo group engaged in the same learning trials, but with a partner. Novices in both groups performed more accurately in pitch and time when learning in synchrony and turn-taking than in imitation. No differences were found between solo and joint learning. These results suggest that musical learning benefits from a shared, in-the-moment, musical experience, where responsibilities and cognitive resources are distributed between biological (i.e., peers) and hybrid (i.e., participant(s) and computer) assemblies.

The OPERA hypothesis theorizes how musical experience heightens perceptual acuity to lexical tones. One missing element in the hypothesis is whether musical advantage is general to all or specific to some lexical tones. To further extend the hypothesis, this study investigated whether English musicians consistently outperformed English nonmusicians in perceiving a variety of Cantonese tones. In an AXB discrimination task, the musicians exhibited superior discriminatory performance over the nonmusicians only in the high level, high rising, and mid-level tone contexts. Similarly, in a Cantonese tone sequence recall task, the musicians significantly outperformed the nonmusicians only in the contour tone context but not in the level tone context. Collectively, the results reflect the selectivity of musical advantage—musical experience is only advantageous to the perception of some but not all Cantonese tones, and elements of selectivity can be introduced to the OPERA hypothesis. Methodologically, the findings highlight the need to include a wide variety of lexical tone contrasts when studying music-to-language transfer.

Integrating methods from experimental social psychology and music perception, we tested the hypothesis that when listeners personally like a musician, they will be more inclined to experience his or her music as both provoking movement and as subjectively pleasurable, the two core features of perceived groove. In Experiment 1, participants were exposed to a set of moderately-syncopated, high-groove drum-breaks which they were led to believe were either produced by a relatively likable or unlikable musician. In line with predictions, participants led to find the musician more versus less likable rated the same drum-breaks as more evocative of both the urge to move and of feelings of pleasure. When participants in a follow-up study (Experiment 2) were administered the exact same manipulation of likability, but exposed to highly-syncopated, low-groove drum-breaks, these effects were eradicated, suggesting that the results of Experiment 1 were not merely due to demand characteristics or response biases. Together, these findings support the notion that listeners are more responsive to “participating in the music” when they are relatively motivated to affiliate with the musician(s). Methodological limitations and directions for future research on the social psychological underpinnings of groove are discussed.

Speech and song have frequently been treated as contrasting categories. We here observe a variety of collective activities in which multiple participants utter the same thing at the same time, a behavior we call joint speech. This simple empirical definition serves to single out practices of ritual, protest, and the enactment of identity that span the range from speech to song and allows consideration of the manner in which such activities serve to ground collectives. We consider how the musical elements in joint speech such as rhythm, melody, and instrumentation are related to the context of occurrence and the purposes of the participants. While music and language have been greatly altered by developments in media technologies—from writing to recordings—joint speech has been, and continues to be, an integral part of practices, both formal and informal, from which communities derive their identity. The absence of joint speech from the scientific treatment of language has made language appear as an abstract intellectual and highly individualized activity. Joint speech may act as a corrective to draw our attention back to the voice in context, and the manner in which collective identities are enacted.

Music expertise has been shown to enhance emotion recognition from speech prosody. Yet, it is currently unclear whether music training enhances the recognition of emotions through other communicative modalities such as vision and whether it enhances the feeling of such emotions. Musicians and nonmusicians were presented with visual, auditory, and audiovisual clips consisting of the biological motion and speech prosody of two agents interacting. Participants judged as quickly as possible whether the expressed emotion was happiness or anger, and subsequently indicated whether they also felt the emotion they had perceived. Measures of accuracy and reaction time were collected from the emotion recognition judgements, while yes/no responses were collected as indication of felt emotions. Musicians were more accurate than nonmusicians at recognizing emotion in the auditory-only condition, but not in the visual-only or audiovisual conditions. Although music training enhanced recognition of emotion through sound, it did not affect the felt emotion. These findings indicate that emotional processing in music and language may use overlapping but also divergent resources, or that some aspects of emotional processing are less responsive to music training than others. Hence music training may be an effective rehabilitative device for interpreting others’ emotion through speech.

In charting the “territory between speech and song,” Cummins (2020) identifies various forms of vocal behavior involving “multiple people uttering the same thing at the same time”—what the author calls “joint speech.” I interrogate this conceptual framework in light of specific examples both musical and linguistic, which suggest a usefully expanded category: “collaborative vocality.” At the same time, I also propose a distinctly musical account of joint speech that ultimately affirms the conventional separation between music and language. Central to this account is an analysis of the unique character of singing and an insistence on the centrality of pleasure in musical experience.

In his article “The Territory Between Speech and Song: A Joint Speech Perspective,” Cummins (2020) argues that research has failed to adequately recognize an important category of vocal activity that falls outside of the domains of language and music, at least as they are typically defined. This category, referred to by Cummins as joint speech , spans a range of vocal activity so broad that it is not possible to define it using musical or phonetic terms. Instead, the feature that draws the varied examples together is vocal activity that is coordinated across participants and embedded in a physical and social context. In this invited commentary, I argue that although joint speech adds an important thread to the discourse on the relations between speech and song by putting an emphasis on the collective, it is ultimately related to a wider class of joint action phenomena found in the animal kingdom.

The pleasurable desire to move to a beat is known as groove and is partly explained by rhythmic syncopation. While many contemporary groove-directed genres originated in the African diaspora, groove music psychology has almost exclusively studied European or North American listeners. While cross-cultural approaches can help us understand how different populations respond to music, comparing African and Western musical behaviors has historically tended to rely on stereotypes. Here we report on two studies in which sensorimotor and groove responses to syncopation were measured in university students and staff from Cape Coast, Ghana and Williamstown, MA, United States. In our experimental designs and interpretations, we show sensitivity towards the ethical implications of doing cross-cultural research in an African context. The Ghanaian group showed greater synchronization precision than Americans during monophonic syncopated patterns, but this was not reflected in synchronization accuracy. There was no significant group difference in the pleasurable desire to move. Our results have implications for how we understand the relationship between exposure and synchronization, and how we define syncopation in cultural and musical contexts. We hope our critical approach to cross-cultural comparison contributes to developing music psychology into a more inclusive and culturally grounded field.
