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.

S killed ensemble musicians coordinate with high precision, even when improvising or interpreting loosely defined notation. Successful coordination is supported primarily through shared attention to the musical output; however, musicians also interact visually, particularly when the musical timing is irregular. This study investigated the performance conditions that encourage visual signaling and interaction between ensemble members. Piano and clarinet duos rehearsed a new piece as their body motion was recorded. Analyses of head movement showed that performers communicated gesturally following held notes. Gesture patterns became more consistent as duos rehearsed, though consistency dropped again during a final performance given under no-visual-contact conditions. Movements were smoother and interperformer coordination was stronger during irregularly timed passages than elsewhere in the piece, suggesting heightened visual interaction. Performers moved more after rehearsing than before, and more when they could see each other than when visual contact was occluded. Periods of temporal instability and increased familiarity with the music and co-performer seem to encourage visual interaction, while specific communicative gestures are integrated into performance routines through rehearsal. We propose that visual interaction may support successful ensemble performance by affirming coordination throughout periods of temporal instability and serving as a social motivator to promote creative risk-taking.

Some movements that musicians make are non-essential to their instrumental playing, yet express their intentions and interpretations of music’s structures. One such potential interpretation is the choice to emphasize short melodic groupings or to integrate these groupings into a phrase. This study aimed to characterize the nature of head motions associated with either interpretation by having cellists play two versions of a musical excerpt: 1) with short groupings specified, and 2) with long groupings specified. Cellists were filmed by two video cameras (front and right-side perspective) and the positions of their forehead and cheek were analyzed in their respective two-dimensional spaces. We hypothesized that the amount and frequency of movements would change according to the intended grouping. The results show that, overall, participants’ heads move more frequently when intending short groupings compared to long groupings. However, the extent of the change in motion varied across different sections of the excerpt. It appears that performers may invest more effort to emphasize the intended interpretation when a given local pitch structure more easily affords alternative interpretations. Our results illustrate that performers can embody melodic groupings based on intended interpretation.

Growing interest in studies on the relationship between music and movement has given rise to many paradigms and theories, including embodied approaches that provide interesting methodologies in studies on music and dance. Insight into the relation between dance and music is particularly important for the Baroque period, as a direct connection between music and dance was omnipresent, even if music was not used to dance to. Many types of Baroque dances existed, each of them with particular dance steps and a specific character, requiring a specific tempo. However, in music performance practice today, the link with the original dance movement is often lost and the tempo variation can be very large. The aim of this study is to compare the interpretations of dancers and musicians regarding Baroque music and dance in an experimental setting. First, we investigate the influence of dance movement on the musical interpretation of a series of Baroque dances. The pieces were recorded both with and without dance accompaniment and the tempo and timing in the different versions were compared. In the second part, dancers performed a particular choreography to music that varied in tempo. Video analysis and questionnaire data were used to evaluate the different performances. The results were compared with the tempi of music recordings of the same dance types, showing a clear difference between music and dance performance. Musicians adapt their interpretation when performing together with the dancers, and the optimal tempo range found for certain Baroque dances coincides only partly with the tempi commonly found in music recordings. The direct link between music and movement and its mutual influence illustrates the importance of an embodied approach in music performance, where in this case dance movement gives concrete information for a “historically informed” performance.

Groove is a sensation of movement or wanting to move when we listen to certain types of music; it is central to the appreciation of many styles such as Jazz, Funk, Latin, and many more. To better understand the mechanisms that lead to the sensation of groove, we explore the relationship between groove and systematic microtiming deviations. Manifested as small, intentional deviations in timing, systematic microtiming is widely considered within the music community to be a critical component of music performances that groove. To investigate the effect of microtiming on the perception of groove we synthesized typical rhythm patterns for Jazz, Funk, and Samba with idiomatic microtiming deviation patterns for each style. The magnitude of the deviations was parametrically varied from nil to about double the natural level. In two experiments, untrained listeners and experts listened to all combinations of same and different music and microtiming style and magnitude combinations, and rated liking, groove, naturalness, and speed. Contrary to a common and frequently expressed belief in the literature, systematic microtiming led to decreased groove ratings, as well as liking and naturalness, with the exception of the simple short-long shuffle Jazz pattern. A comparison of the ratings between the two listener groups revealed this effect to be stronger for the expert listener group than for the untrained listeners, suggesting that musical expertise plays an important role in the perception and appreciation of microtiming in rhythmic patterns.

Listening to music often is associated with spontaneous body movements frequently synchronized with its periodic structure. The notion of embodied cognition assumes that intelligent behavior does not emerge from mere passive perception, but requires goal-directed interactions between the organism and its environment. According to this view, one could postulate that we may use our bodily movements to help parse the metric structure of music. The aim of this study was to investigate how pulsations on different metrical levels manifest in music-induced movement. Musicians were presented with a piece of instrumental music in 4/4 time, played at four different tempi ranging from 92 to 138 bpm. Participants were instructed to move to the music, and their movements were recorded with a high quality optical motion capture system. Subsequently, signal processing methods and principal components analysis were applied to extract movement primitives synchronized with different metrical levels. We found differences between metric levels in terms of the prevalence of synchronized eigenmovements. For instance, mediolateral movements of arms were found to be frequently synchronized with the tactus level pulse, while rotation and lateral flexion of the upper torso were commonly found to exhibit periods of two and four beats, respectively. The results imply that periodicities on several metric levels are simultaneously present in music-induced movement. This could suggest that the metric structure of music is encoded in these movements.

There is a quality of music that makes people tap their feet, rock their head, and get up and dance. The consistency of this experience among listeners was examined, in terms of differences in ratings across 64 music examples taken from commercially available recordings. Results show that ratings of groove, operationally defined as “wanting to move some part of the body in relation to some aspect of the sound pattern,” exhibited considerable interindividual consistency. Covariance patterns among the 14 rated words indicated four prominent factors, which could be labeled regular-irregular, groove, having swing, and flowing. Considering the wide range of music examples used, these factors are interpreted as reflecting psychological dimensions independent of musical genre and style.
