História e música: canção popular e conhecimento histórico

Esse trabalho procura levantar e discutir algumas questões teóricas e metodológicas que surgem das relações entre História, música e a canção popular. As transformações teóricas, as novas concepções de material documental e a prática renovada do historiador determinaram a incorporação de novas linguagens pela História. Seguindo nessa trilha, o artigo pretende justamente mostrar, a partir de uma perspectiva interdisciplinar, como as relações entre história, cultura e música popular podem desvendar processos pouco conhecidos e raramente levantados pela historiografia. Para alcançar esse objetivo é necessário ultrapassar a tradicional concepção de história da música e, para isso, tenta-se refletir e organizar alguns elementos para compreender melhor as múltiplas relações entre a canção e o conhecimento histórico. A discussão aponta para a possibilidade e, principalmente, a viabilidade do historiador tratar a música e a canção popular como uma fonte documental importante para mapear e desvendar zonas obscuras da história, sobretudo aquelas relacionadas com os setores subalternos e populares.

Relationship between cardiac autonomic regulation and auditory mechanisms: Importance for growth and development

The literature has already demonstrated that auditory stimulation with music influences the cardiovascular system. In this study, we performed a literature review in order to investigate the relationship between auditory mechanisms and cardiac autonomic regulation. The selected studies indicated that there is a strong correlation between noise intensity and vagal-sympathetic balance. Also, it was reported that music therapy improved heart rate variability in anthracycline-treated breast cancer patients. It was hypothesized that dopamine release in the striatal system induced by pleasure songs are involved in the cardiac autonomic regulation. Further studies are necessary to add new elements in the literature to improve new therapies to treat cardiovascular disorders.

The effects of different styles of musical auditory stimulation on cardiac autonomic regulation in healthy women

The literature investigated the effects of chronic baroque music auditory stimulation on the cardiovascular system. However, it lacks in the literature the acute effects of different styles of music on cardiac autonomic regulation. To evaluate the acute effects of baroque and heavy metal music on heart rate variability (HRV) in women. The study was performed in 21 healthy women between 18 and 30 years old. We excluded persons with previous experience with music instrument and those who had affinity with the song styles. All procedures were performed in the same sound-proof room. We analyzed HRV in the time (standard deviation of normal-to-normal respiratory rate (RR) intervals, root-mean square of differences between adjacent normal RR intervals in a time interval, and the percentage of adjacent RR intervals with a difference of duration greater than 50 ms) and frequency (low frequency [LF], high frequency [HF], and LF/HF ratio) domains. HRV was recorded at rest for 10 min. Subsequently they were exposed to baroque or heavy metal music for 5 min through an earphone. After the first music exposure they remained at rest for more 5 min and them they were exposed again to baroque or heavy metal music. The sequence of songs was randomized for each individual. The power analysis provided a minimal number of 18 subjects. Shapiro-Wilk to verify normality of data and analysis of variance for repeated measures followed by the Bonferroni test for parametric variables and Friedman's followed by the Dunn's post-test for non-parametric distributions. During the analysis of the time-domain indices were not changed. In the frequency-domain analysis, the LF in absolute units was reduced during the heavy metal music stimulation compared to control. Acute exposure to heavy metal music affected the sympathetic activity in healthy women.

Previous exposure to musical auditory stimulation immediately influences the cardiac autonomic responses to the postural change maneuver in women

Background: Chronic exposure to musical auditory stimulation has been reported to improve cardiac autonomic regulation. However, it is not clear if music acutely influences it in response to autonomic tests. We evaluated the acute effects of music on heart rate variability (HRV) responses to the postural change maneuver (PCM) in women. Method: We evaluated 12 healthy women between 18 and 28 years old and HRV was analyzed in the time (SDNN, RMSSD, NN50 and pNN50) and frequency (LF, HF and LF/HF ratio) domains. In the control protocol, the women remained at seated rest for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. In the music protocol, the women remained at seated rest for 10 minutes, were exposed to music for 10 minutes and quickly stood up within three seconds and remained standing still for 15 minutes. HRV was recorded at the following time: rest, music (music protocol) 0–5, 5–10 and 10–15 min during standing. Results: In the control protocol the SDNN, RMSSD and pNN50 indexes were reduced at 10–15 minutes after the volunteers stood up, while the LF (nu) index was increased at the same moment compared to seated rest. In the protocol with music, the indexes were not different from control but the RMSSD, pNN50 and LF (nu) were different from the music period. Conclusion: Musical auditory stimulation attenuates the cardiac autonomic responses to the PCM.

Response of cardiac autonomic modulation after a single exposure to musical auditory stimulation

The acute effects after exposure to different styles of music on cardiac autonomic modulation assessed through heart rate variability (HRV) analysis have not yet been well elucidated. We aimed to investigate the recovery response of cardiac autonomic modulation in women after exposure to musical auditory stimulation of different styles. The study was conducted on 30 healthy women aged between 18 years and 30 years. We did not include subjects having previous experience with musical instruments and those who had an affinity for music styles. The volunteers remained at rest for 10 min and were exposed to classical baroque (64-84 dB) and heavy metal (75-84 dB) music for 10 min, and their HRV was evaluated for 30 min after music cessation. We analyzed the following HRV indices: Standard deviation of normal-to-normal (SDNN) intervals, root mean square of successive differences (RMSSD), percentage of normal-to-normal 50 (pNN50), low frequency (LF), high frequency (HF), and LF/HF ratio. SDNN, LF in absolute units (ms (2) ) and normalized (nu), and LF/HF ratio increased while HF index (nu) decreased after exposure to classical baroque music. Regarding the heavy metal music style, it was observed that there were increases in SDNN, RMSSD, pNN50, and LF (ms (2) ) after the musical stimulation. In conclusion, the recovery response of cardiac autonomic modulation after exposure to auditory stimulation with music featured an increased global activity of both systems for the two musical styles, with a cardiac sympathetic modulation for classical baroque music and a cardiac vagal tone for the heavy metal style.

Brain activation during anticipation of sound sequences

Music consists of sound sequences that require integration over time. As we become familiar with music, associations between notes, melodies, and entire symphonic movements become stronger and more complex. These associations can become so tight that, for example, hearing the end of one album track can elicit a robust image of the upcoming track while anticipating it in total silence. Here, we study this predictive “anticipatory imagery” at various stages throughout learning and investigate activity changes in corresponding neural structures using functional magnetic resonance imaging. Anticipatory imagery (in silence) for highly familiar naturalistic music was accompanied by pronounced activity in rostral prefrontal cortex (PFC) and premotor areas. Examining changes in the neural bases of anticipatory imagery during two stages of learning conditional associations between simple melodies, however, demonstrates the importance of fronto-striatal connections, consistent with a role of the basal ganglia in “training” frontal cortex (Pasupathy and Miller, 2005). Another striking change in neural resources during learning was a shift between caudal PFC earlier to rostral PFC later in learning. Our findings regarding musical anticipation and sound sequence learning are highly compatible with studies of motor sequence learning, suggesting common predictive mechanisms in both domains.

Introduction XXIX European Seminar in Ethnomusicology: Cultural Mapping and Musical Diversity

«Cultural mapping» has become a central keyword in the UNESCO strategy to protect world cultural and natural heritage. It can be described as a tool to increase the awareness of cultural diversity. As Crawhall (2009) pointed out, cultural mapping was initially considered to represent the «landscapes in two or three dimensions from the perspectives of indigenous and local peoples». It thus transforms the intangible cultural heritage to visible items by establishing profiles of cultures and communities, including music traditions. Cultural mapping is used as a resource for a variety of purposes as broad as peace building, adaptation to climate change, sustainability management, heritage debate and management, but can also become highly useful in the analysis of conflict points. Music plays a significant role in each of these aspects. This year’s symposium invites to highlight, yet also to critically reassess this topic from the following ethnomusicological perspectives: - The method of cultural mapping in ethnomusicology What approaches and research techniques have been used so far to establish musical maps in this context? What kinds of maps have been developed (and, for example, how far do these relate to indigenous mental maps that have only been transmitted orally)? How far do these modern approaches deviate from the earlier cultural mapping approaches of the cultural area approaches that were still evident with Alan P. Merriam and in Alan Lomax` Cantometrics? In how far are the methods of cultural mapping and of ethnomusicological fieldwork different and how can they benefit from each other? - Intangible cultural heritage and musical diversity As the 2003 UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage pointed out in Article 12, each state signing the declaration «shall draw up, in a manner geared to its own situation, one or more inventories of the intangible cultural heritage, present in its territory and monitor these.» This symposium calls for a critical re-assessment of the hitherto established UNESCO intangible cultural heritage lists. The idea is to highlight the sensitive nature and the effects of the various heritage representations. «Heritage» is understood here as a selection from a selection – a small subset of history that relates to a given group of people in a particular place, at a specific time (Dann and Seaton 2001:26). This can include presentations of case studies, yet also a critical re-analysis of the selection process, e.g. who was included – or even excluded (and why)? Who were the decision makers? How can the role of ethnomusicology be described here? Where are the (existent and possible) conflict points (politically, socially, legally, etc.)? What kinds of solution strategies are available to us? How is the issue of diversity – that has been so strongly emphasized in the UNESCO declarations – reflected in the approaches? How might diversity be represented in future approaches? How does the selection process affect musical canonization (and exclusion)? What is the role of archives in this process? - Cultural landscape and music As defined by the World Heritage Committee, cultural landscapes can be understood as a distinct geographical area representing the «combined work of nature and man» (http://whc.unesco.org/en/culturallandscape/). This sub-topic calls for a more detailed – and general – exploration of the exact relation between nature/landscape (and definition of such) and music/sound. How exactly is landscape interrelated with music – and identified (and vice versa)? How is this interrelation being applied and exploited in a (inter-)national context?

O cérebro sócio-musical: estudo de uma experiência de educação musical

A prática musical tem efeitos positivos no desenvolvimento humano, envolvendo aspectos cognitivos, emocionais, motivacionais e sociais, que implicam em alterações no processamento cerebral. O número de Programas de Educação Musical (PEMs) com enfoque em populações jovens em vulnerabilidade social tem crescido no Brasil e no mundo. Dessa maneira, torna-se importante a realização de estudos que verifiquem os efeitos de PEMs no desenvolvimento destas populações. O objetivo do presente estudo é investigar os impactos de uma experiência de um PEM sobre os aspectos psicológicos de seus estudantes, mais especificamente a autoestima, as habilidades sociais e o funcionamento executivo. A coleta de dados foi realizada em um PEM da cidade de Ribeirão Preto SP e em duas escolas regulares de ensino, uma particular e outra da rede pública. Participaram do estudo 69 crianças e adolescentes com idades entre 10 e 17 anos, divididos em três grupos, a saber: Grupo Iniciante (GI), composto por alunos com até 12 meses de matrícula no PEM; Grupo Experiente (GE), composto por alunos com mais de 24 meses de matrícula no PEM; e Grupo Controle (GC), constituído por participantes sem qualquer envolvimento com aprendizado musical. Cada grupo foi composto por 23 estudantes. Os três grupos de participantes responderam aos seguintes testes psicológicos: Escala de Autoestima de Rosenberg (EAR), Matson Evaluation of Social Skills with Youngsters (MESSY) e Teste de Stroop. Também foram realizadas entrevistas semi-estruturadas com todos os estudantes dos grupos GI e GE, dez estudantes do PEM que não compuseram nenhum grupo por não possuírem o pré-requisito de tempo de matrícula exigido, seis responsáveis legais dos estudantes e doze profissionais do PEM. As entrevistas tiveram a função de fornecerem relatos verbais a respeito dos impactos percebidos nos estudantes pelo envolvimento com o PEM. Os dados dos testes psicológicos foram analisados através dos testes estatísticos ANOVA, Mann-Whitney e t de Student e as entrevistas foram analisadas através da investigação qualitativa em educação. As análises dos testes psicológicos mostraram que os GI e GE não possuem diferenças entre si para nenhuma das variáveis de estudo. O GC apresentou escores inferiores aos GI e GE para a Autoestima e escores superiores para Solidão e Ansiedade Social, indicando que o envolvimento com o PEM pode acarretar em ganhos nessas habilidades. A partir da análise das entrevistas foram construídas três categorias de codificação relacionadas a impactos comportamentais do envolvimento com o PEM, a saber: relacionamento interpessoal, desenvolvimento de habilidades intrapessoais e envolvimento com música e desenvolvimento humano na perspectiva de profissionais e responsáveis legais. A análise das entrevistas indicou que a participação no PEM está relacionada a impactos positivos na autoestima, habilidades sociais e funcionamento executivo dos participantes. Os resultados foram discutidos buscando interrelaciona-los de maneira a integrar os dados colhidos por meio dos testes psicológicos e através das entrevistas. Conclui-se que a participação em PEMs com enfoque no resgate social de populações vulneráveis possui influência no desenvolvimento de crianças e adolescentes, indicando que o uso da educação musical caracteriza uma importante estratégia de intervenção social.
