This work, from of theorist perspective of Historical-Critical Pedagogy, presents the school Music Education like a social mediator environment between the practices, listening and musical everydaylife knowledges and the not-quotidian, which are constitution and accumulated, throughout the centuries of History, by the human societies. The purpose is to present a possible theorist foundation to define the importance of Music Education insert in the elementary school, like a subject destined to guarantee the whole children formation and the enrichment of their relations with the music. It is a theorist reflection that indicates the importance of observation of the quotidian and not-quotidian knowledges characteristics, moreover of complete importance of formal education and, in specific, of school Music Education on human development.

Este artigo tem por objetivos rever, mediante análise bibliográfica e de fontes primárias, a história de um de nossos símbolos musicais pátrios, o Hino da Independência, de Dom Pedro I, bem como trazer novos subsídios para o estudo da gênese da imprensa musical brasileira. Tem, igualmente, por escopo divulgar peculiaridades de uma antiga e pouco conhecida partitura desse hino, já não mais presentes em modernas edições de tal composição.

O monodrama Erwartung, de Arnold Schoenberg, foi caracterizado por um lado como síntese do expressionismo e, por outro, como uma composição não definível por meio de categorias formais. Esta convergência entre expressão e negação da forma, apontada por Carl Dahlhaus, é o ponto de partida deste texto, cujo objetivo é sustentar, mais do que uma simples convergência, uma relação determinada entre expressão e negação da forma, ou da convenção. Isto é realizado em três momentos: primeiro, desenvolve-se o conceito adorniano de fetichismo musical; segundo, aborda-se a relação entre a expressão e a convenção à luz do problema do fetichismo musical, o que permite aproximar noções como a negação da convenção, a negação romântica do objetivismo musical em prol da expressão subjetiva e a recusa de materiais fetichizados; em terceiro lugar, aborda-se Erwartung, mostrando como o problema da convenção, do objetivismo e do fetichismo não deixam de aparecer em uma peça que leva às últimas consequências a radicalização da expressão pela negação da convenção.

A memória operacional e a atividade musical ativam áreas encefálicas recíprocas e homólogas, contudo não há evidências se o treino musical pode ampliar a capacidade da memória operacional. Objetivo: Avaliar o desempenho do treino musical sob a memória operacional em crianças de 9 e 10 anos de idade, praticantes de treino musical e sem experiência musical. PARTICIPANTES: Crianças Iniciantes (n=20), Veteranas (n=20) e Grupo Controle (n=20). MATERIAIS: Instrumentos computadorizados para avaliação da memória operacional. RESULTADOS: Crianças veteranas apresentaram melhores pontuações no BCPR (Teste de Repetição de Pseudopalavras para crianças brasileiras) e em subtestes da AWMA (Avaliação Automatizada da Memória Operacional). CONCLUSÃO: O treino musical parece ter contribuído para o desenvolvimento da memória operacional em crianças veteranas no programa de treino musical.

Action-research is a model of scientific investigation which is not widely used in musical teaching, even considering its relevant application in the social sciences. David Tripp (2005) classifies it as a type of action-investigation which is used to define any process that follows a cycle where the practice is improved by the systematic oscillation from acting in the field of practice to investigating into it. With the approval by the Brazilian National Congress of Law 17,769, on August 18, 2008, and with the supplementary legislation, we understand that its use in the musical education would be beneficial. This justification has motivated the writing of this article, which approached the characteristics, functions and usefulness of the action-research. The consulted authors were, among others, D. Tripp, M. Thiollent, Maria A. Franco, G. Morceau, and Maria G. de Miranda. Two examples of Master's dissertations which adopted this type of research were mentioned.

In this paper we study the main modalities of music education in Brazil and how they can be compared to different views worldwide. Recognition that modern practices in music education are inserted in contemporary knowledge paradigms shows their relevance to a changing world. According to this contemporary paradigm the practices included herein point to alternatives in the relationship between men and themselves, men and other men and men and the environment. They also encourage cooperation, the relationship among the arts, the conduction of actions ruled by the principles of ecology and the recovery of values lost or weakened.

This paper discusses two pitch detection algorithms (PDA) for simple audio signals which are based on zero-cross rate (ZCR) and autocorrelation function (ACF). As it is well known, pitch detection methods based on ZCR and ACF are widely used in signal processing. This work shows some features and problems in using these methods, as well as some improvements developed to increase their performance. © 2008 IEEE.

This text aims to argument about the historic relation between Mário de Andrade's project to Brazilian music (his national sound utopia, as Arnaldo Contier called it) and one of its possible realization with bossa nova. The text presents in general lines the Andradian project, its committed character, its incursions in the problems of popular and erudite and its filiations to the national obsession with formation. It exposes punctually the possible comprehension of bossa nova as a modernist project, suggesting a logicality of continuity in Brazilian musical experience.

Musical genre classification has been paramount in the last years, mainly in large multimedia datasets, in which new songs and genres can be added at every moment by anyone. In this context, we have seen the growing of musical recommendation systems, which can improve the benefits for several applications, such as social networks and collective musical libraries. In this work, we have introduced a recent machine learning technique named Optimum-Path Forest (OPF) for musical genre classification, which has been demonstrated to be similar to the state-of-the-art pattern recognition techniques, but much faster for some applications. Experiments in two public datasets were conducted against Support Vector Machines and a Bayesian classifier to show the validity of our work. In addition, we have executed an experiment using very recent hybrid feature selection techniques based on OPF to speed up feature extraction process. © 2011 International Society for Music Information Retrieval.

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.
