Joint Drumming in Brazilian and German Preschool Children Cultural Differences in Rhythmic Entrainment, but No Prosocial Effects

As a core feature of musical rituals around the world, humans synchronize their movements to the pulse of a shared acoustic pattern—a behavior called rhythmic entrainment. The purpose of the present study was (a) to examine the development of rhythmic entrainment with a focus on the role of experience and (b) to follow one line of evidence concerning its adaptive function. We hypothesized (a) that children learn how to synchronize movements to sound during social interactions, where they experience this behavior as a convention of the surrounding culture’s practice, and (b) that rhythmic entrainment has an adaptive value by allowing several people to coordinate their actions, thereby creating group cohesion and ultimately promoting cooperativeness. We compared the spontaneous synchronization behavior of Brazilian and German preschool children during joint drumming with an experimenter, either vis-à-vis or separated by a curtain, versus drumming along a playback beat. Afterward, we measured the children’s prosocial tendencies toward the experimenter. We found that Brazilian children were more likely than German children to spontaneously synchronize their drumming in a social setting, even if the codrummer was hidden from view. According to hypothesis, the variation in individual synchronization accuracy between and within the two samples could be partly explained by differences in individual experience with active musical practice, as revealed by parental interviews. However, we found no differences in children’s prosocial tendencies depending on whether they just had drummed alone or together with the experimenter.

An equal start: absence of group differences in cognitive, social, and neural measures prior to music or sports training in children

Several studies comparing adult musicians and non-musicians have provided compelling evidence for functional and anatomical differences in the brain systems engaged by musical training. It is not known, however, whether those differences result from long-term musical training or from pre-existing traits favoring musicality. In an attempt to begin addressing this question, we have launched a longitudinal investigation of the effects of childhood music training on cognitive, social and neural development. We compared a group of 6- to 7-year old children at the start of intense after-school musical training, with two groups of children: one involved in high intensity sports training but not musical training, another not involved in any systematic training. All children were tested with a comprehensive battery of cognitive, motor, musical, emotional, and social assessments and underwent magnetic resonance imaging and electroencephalography. Our first objective was to determine whether children who participate in musical training were different, prior to training, from children in the control groups in terms of cognitive, motor, musical, emotional, and social behavior measures as well as in structural and functional brain measures. Our second objective was to determine whether musical skills, as measured by a music perception assessment prior to training, correlates with emotional and social outcome measures that have been shown to be associated with musical training. We found no neural, cognitive, motor, emotional, or social differences among the three groups. In addition, there was no correlation between music perception skills and any of the social or emotional measures. These results provide a baseline for an ongoing longitudinal investigation of the effects of music training.

Childhood Music Training Induces Change in Micro and Macroscopic Brain Structure: Results from a Longitudinal Study

Several studies comparing adult musicians and nonmusicians have shown that music training is associated with structural brain differences. It is not been established, however, whether such differences result from pre-existing biological traits, lengthy musical training, or an interaction of the two factors, or if comparable changes can be found in children undergoing music training. As part of an ongoing longitudinal study, we investigated the effects of music training on the developmental trajectory of childrens brain structure, over two years, beginning at age 6. We compared these children with children of the same socio-economic background but either involved in sports training or not involved in any systematic after school training. We established at the onset that there were no pre-existing structural differences among the groups. Two years later we observed that children in the music group showed (1) a different rate of cortical thickness maturation between the right and left posterior superior temporal gyrus, and (2) higher fractional anisotropy in the corpus callosum, specifically in the crossing pathways connecting superior frontal, sensory, and motor segments. We conclude that music training induces macro and microstructural brain changes in school-age children, and that those changes are not attributable to pre-existing biological traits.

Infants’ Preferential Attention to Sung and Spoken Stimuli:

Caregivers and early childhood teachers all over the world use singing and speech to elicit and maintain infants’ attention. Research comparing infants’ preferential attention to music and speech is inconclusive regarding their responses to these two types of auditory stimuli, with one study showing a music bias and another one indicating no differential attention. The purpose of this investigation was to study 11-month-old infants’ preferential attention to spoken and sung renditions of an unfamiliar folk song in a foreign language (n = 24). The results of an infant-controlled preference procedure showed no significant differences in attention to the two types of stimuli. The findings challenge infants’ well-documented bias for speech over nonspeech sounds and provide evidence that music, even when performed by an untrained singer, can be as effective as speech in eliciting infants’ attention.

Rhythmic Engagement With Music in Early Childhood: A Replication and Extension

The purpose of this study was to replicate and extend previous findings on spontaneous movement and rhythmic engagement with music in infancy. Using the identical stimuli and procedures from the original study, I investigated spontaneous rhythmic movements in response to music, infant-directed speech, and contrasting rhythmic patterns in 30 Brazilian infants (ages 5, 11, and 19 months). Findings were consistent with the original study in that more spontaneous rhythmic movements were found in response to music and metrically regular stimuli than to speech. Brazilian babies, however, showed higher means for spontaneous rhythmic movement to music than those reported in the original study. Consistent with the developmental systems approach, these results suggest that culture plays a larger role in spontaneous rhythmic engagement to music and rhythmic entrainment than previously suggested.

A community of practice in music teacher training: The case of Musicalização Infantil

This article discusses the emergence of a community of practice of student-teachers in music in a Brazilian university outreach program called Musicalização Infantil. It starts with a short introduction to the concept of community of practice. Next, a brief history of the program is presented to contextualize the study, followed by a description of three episodes that took place while the author was program coordinator and student-teacher mentor. These episodes provide a background against which to discuss how the concept of community of practice may be related to music teacher education. Implications for music education, locally and globally, are articulated at the end of the article.

Singing and cultural understanding: A music education perspective

This article explores the relationship between singing and cultural understanding. Singing emerges in infancy and develops through processes of enculturation and socialization. When we sing songs from diverse cultures, we are granted with opportunities to learn about the cultures of others, and gain a better understanding of our own. Thus, singing songs from different cultures may play important roles in the construction of our identities and in how we perceive and understand others, and ultimately ourselves. Cultural understanding, however, is complex in nature and multi-layered. Even if research findings concerning the relationship between singing and cultural understanding are mixed, we argue that there is value in enhancing students’ cultural understanding through singing multicultural songs. Singing multicultural songs can also promote the well being of students. It is beyond the education of music. It is about a comprehensive education of humans as social beings and music as a human endeavor.

The Development of Musical Skills of Underprivileged Children Over the Course of 1 Year: A Study in the Context of an El Sistema-Inspired Program.

Developmental research in music has typically centered on the study of single musical skills (e.g., singing, listening) and has been conducted with middle class children who learn music in schools and conservatories. Information on the musical development of children from different social strata, who are enrolled in community-based music programs, remains elusive. This study examined the development of musical skills in underprivileged children who were attending an El Sistema-inspired program in Los Angeles. We investigated how children, predominantly of Latino ethnicity, developed musically with respect to the following musical skills – pitch and rhythmic discrimination, pitch matching, singing a song from memory, and rhythmic entrainment – over the course of 1 year. Results suggested that participation in an El Sistema-inspired program affects children’s musical development in distinct ways; with pitch perception and production skills developing faster than rhythmic skills. Furthermore, children from the same ethnic and social background, who did not participate in the El Sistema-inspired music program, showed a decline in singing and pitch discrimination skills over the course of 1 year. Taken together, these results are consistent with the idea of musical development as a complex, spiraling and recursive process that is influenced by several factors including type of musical training. Implications for future research are outlined.

Concerted cultivation and music learning: Global issues and local variations

Concerted cultivation has been described as a common, urban middle-class practice concerning the enrollment of children in a variety of age-specific activities that may promote the learning of valuable life skills as well as the development of individual abilities (Lareau, 2003). Music is one such activity. This study investigated the relationship between children’s participation in organized musical activities and concerted cultivation in the discourses of parents, who took part in the MyPlace, MyMusic Research Project. This collaborative project investigated children’s home musical experiences in diverse countries. Although all interviewed parents were highly invested in their children’s organized and unstructured musical experiences, there was much variation in regard to beliefs, values, affordances, and opportunities. Global and local issues are discussed along with implications for future research.

Assessing Music Perception in Young Children: Evidence for and Psychometric Features of the M-Factor

Given the relationship between language acquisition and music processing, musical perception (MP) skills have been proposed as a tool for early diagnosis of speech and language difficulties; therefore, a psychometric instrument is needed to assess music perception in children under 10 years of age, a crucial period in neurodevelopment. We created a set of 80 musical stimuli encompassing seven domains of music perception to inform perception of tonal, atonal, and modal stimuli, in a random sample of 1006 children, 6–13 years of age, equally distributed from first to fifth grades, from 14 schools (38% private schools) in So Paulo State. The underlying model was tested using confirmatory factor analysis. A model encompassing seven orthogonal specific domains (contour, loudness, scale, timbre, duration, pitch, and meter) and one general music perception factor, the “m-factor,” showed excellent fit indices. The m-factor, previously hypothesized in the literature but never formally tested, explains 93% of the reliable variance in measurement, while only 3.9% of the reliable variance could be attributed to the multidimensionality caused by the specific domains. The 80 items showed no differential item functioning based on sex, age, or enrolment in public vs. private school, demonstrating the important psychometric feature of invariance. Like Charles Spearmans g-factor of intelligence, the m-factor is robust and reliable. It provides a convenient measure of auditory stimulus apprehension that does not rely on verbal information, offering a new opportunity to probe biological and psychological relationships with music perception phenomena and the etiologies of speech and language disorders.
