Performance analysis and analysis for performance : a study of Villa-Lobos's Bachianas Brasileiras No. 9

This study of Villa-Lobos’s Bachianas Brasileiras No. 9 aims at gaining insight into the decision-making processes of translating a score into a musical performance. Chapter I presents a discussion of selected issues related to interpretative analysis. Chapter II is an overview of the approaches to recording comparison deemed relevant to the present study. Chapter III is a comparative study of the vocal and string versions of Bachianas Brasileiras No. 9, while Chapter IV offers a structural analysis of the work. Chapter V compares four recordings: the composer’s own with the Orchestre National de La Radiodiffusion Française—EMI 7243 5 66964 2 6; Odaline de la Martinez and the BBC Singers, LNT 102; Michael Tilson Thomas and the New World Symphony —RCA 09026-68538-2; and my own CD, Construção, Orquestra de Câmara Theatro São Pedro- Limited Edition (live recording made on December 11, 1995 in Bayreuth, Germany). This comparison utilizes data obtained with the software Tempo. The tabulation of these results is shown in graphs that compare how matters of tempo flexibility affect each performance. This multi-faceted study shows that although painstaking analysis can lead to insightful solutions, the fleeting nature of musical performance requires an open mind and imagination to deal with the often contradictory directives of the score.

Estética e música na obra de Luiz Cosme

Neste trabalho é realizada a análise dos fundamentos estéticos presentes nos escritos de Luiz Cosme em correlação com os aspectos técnicos e compositivos encontrados em sua produção musical. O exame dos fundamentos estético-musicais presentes na obra teórica de Luiz Cosme é realizado com base no seu vínculo com os princípios dos músicos nacionalistas e do Grupo Música Viva. Cosme se posicionou independentemente com relação aos dois grupos, ao incorporar valores de ambos em seus trabalhos. Além das discussões imediatamente ligadas ao modernismo musical brasileiro, Luiz Cosme valeu-se do pensamento de Henri Bergson para formular seus conceitos musicais com base na diferenciação entre a duração objetiva e a duração subjetiva. Na obra musical de Luiz Cosme, são empregados diferentes procedimentos de estruturação do material sonoro. O compositor valeu-se de estruturas diatônicas tonais e modais, processos hexacordais com base na escala de tons inteiros, estruturas cromáticas tonais e atonais e processos dodecafônicos de organização das alturas. A produção musical de Cosme pode ser dividida em três gêneros musicais – música vocal, música de câmara e música orquestral – que se ramificam em três fases diferenciadas. O característico na produção de Cosme está em que os processos de estruturação sonora se propagam em todas as fases compositivas, sendo que cada novo método é incorporado aos anteriores, sem necessariamente substituí-los. Com isso, percebe-se que a música de Luiz Cosme caracteriza-se pela diversidade de materiais, elaborados com distintos processos de estruturação. Esse fator o coloca como um compositor único no meio musical brasileiro da primeira metade do século XX, que se empenhou em desenvolver seus próprios princípios estéticos e formulações teóricas, com base no conhecimento da tradição que o cercava, assim como se dedicou a desenvolver um estilo peculiar que o posicionou como um músico independente no modernismo musical brasileiro.

Cantar com as mídias eletrônicas : um estudo de caso com jovens

Este estudo investigou o canto intermediado pelas mídias eletrônicas e os processos de aprendizagem musical de cinco jovens, procurando responder à seguinte questão: que funções pedagógico-musicais exercem as mídias sobre as práticas músico-vocais dos jovens? E como subquestões: quais mídias eletrônicas os jovens utilizam para o canto? De que maneira os jovens o fazem? A metodologia adotada foi o estudo de caso, utilizando entrevistas e observações. Para compreender as relações dos jovens com a música, com o canto e as mídias eletrônicas, a investigação se apoiou em autores tais como: Gembris, Kraemer e Maas (1997), Baacke, Sander e Vollbrecht (1988), Münch (1998), Souza (1999; 2000; 2002) Schläbitz (1997; 2003) e Funk-Hennigs (2003). O estudo evidenciou que as mídias eletrônicas têm diferentes funções na atividade músico-vocal dos jovens e que, nesse ambiente midiático, incluem, muito particularmente, a auto-aprendizagem, a identificação e a autonomia nas escolhas musicais, além da possibilidade de cantar acompanhando seus cantores e suas músicas escolhidos.

O corpo tornado voz : a experiência pedagógica da peça radiofônica

Este trabalho apresenta o rádio, mais especificamente a peça radiofônica, como uma experiência pedagógica para atores que assim ampliam seu repertório e tornam a voz protagonista da ação. Entendendo a linguagem radiofônica como linguagem artística e o rádio como um meio expressivo, o estudo pretende um conhecimento vocal voltado para o efeito da voz, sua dimensão temporal e espacial e o estatuto de corpo que ela assume nessas condições. Traz a perspectiva da pedagogia do ator, considerando o ouvinte como interlocutor, sem o que a ação do ator não se concretiza. Utiliza como objeto de pesquisa, a investigação O trabalho do ator voltado para um veículo radiofônico, realizada no âmbito do Departamento de Arte Dramática, Instituto de Artes da Universidade Federal do Rio Grande do Sul, e busca sistematizar para o exercício radiofônico as práticas desenvolvidas pelos atores em seu processo de criação. Para tanto, articula diálogos com as vozes e idéias de Rudolf Arnheim, Werner Klippert, Eduardo Meditsch, Constantin Stanislavski, João Francisco Duarte Junior e Jorge Larrosa, entre outros. Como desdobramento, mostra a possibilidade de promover a oralidade e o exercício radiofônico como expressões individuais e como experiências criativas coletivas e pedagógicas, em atividades para a sala de aula em todos os níveis de ensino, para a oficina e para a ação cultural. Demarca, ainda, a busca por uma expressão radiofônica contemporânea, uma linguagem que faça sentido hoje, abrindo espaço para a escuta ainda que num mundo coberto de imagens.

Vem ouvir o verso de teu cantador : amos, cantadores e toadas no Boi-Bumbá Caprichoso Belém/PA

This thesis aims to investigating the cantadores and the toadas in the Boi Bumbá, debating questions which put together around the construction and performance of amo s and cantador s role in the Boi Bumbá Caprichoso of Belém-PA city and exploring the extent of toadas its characteristics, functions, the uses that are made of theirs and the relations that establishes between them and the cantadores. The problematic of the research consisted on analysing what the amos, cantadores and toadas represent in the whole context of boi-bumbá plays in Belém, nowadays. Considering this perspective, I tried to identify on Boi Caprichoso the most meaningful expressions which were related to toadas and how the roles of amo and cantador were performed. Participative observation, ethnical research, open and semistructured interviews were used as research methods. The role performances on Boi Caprichoso plays an essential part on the playing realization, highlighting themselves as pivotal characters. These performances, characterized by the vocal presence, also highlighted the size that toadas occupy in the whole play, and pointed the way for an emerging model of presentation, in which both toada and cantador appear as central figures

O ator que canta um conto: a manipulação de parâmetros musicais na voz do ator

This research started with an investigation about the theatrical speaking. Through an empirical methodology that analyzed a practical experience of creating a play and bibliographical research, the actress/researcher investigated ways to manipulate musical parameters as tools in the creation process of the actor s voice. The actress/researcher attempted to connect theory and practice, moved by the desire to find a vocal expression in theater that unfolds as living and transforming movement. This dissertation also contains the report of pedagogical experiences, in which the actress/researcher explored strategies to teach the appropriation of musical parameters in the construction of the vocal work of the actor. Considering that speaking in theater is closer to singing than everyday speech, she concluded that the actor may compose music as a music composer does in the elaborating process of building vocal scores. Therefore, she demonstrated that it is of fundamental importance a musical training in the development of the actor.

Structural and ultrastructural characteristics of interrenal gland and chromaffin cell of matrinxa, Brycon cephalus Gunther 1869 (Teleostei-Characidae)

This work presents the structure and ultrastructure of the interrenal gland and chromaffin cells, as well as the morphology of the head kidney of Brycon cephalus, the head kidney is composed of fused bilateral lobes located anterior to the swim bladder and ventrolateral to the spinal column, the parenchyma revealed lympho-haematopoietic tissue, melano-macrophage centres, interrenal gland and chromaffin cells. The interrenal gland consisted of cords or strands of cells grouped around the posterior cardinal vein and their branches. Chromaffin cells are found in small groups, closely associated with the interrenal gland and/or under the endothelium of the posterior cardinal vein. So far, the ultrastructural analysis has revealed only one interrenal cell type which contained abundant smooth endoplasmic reticulum and numerous mitochondria with tubulo-vesicular cristae, characteristic of steroid-producing cells. Two types of chromaffin cells were observed. The first type was characterized by the presence of vesicles with round, strongly electron-dense granules, which were eccentrically located, Such cells were interpreted as noradrenaline cells, Meanwhile, cells which contained smaller vesicles and electron-lucent granules, with a small halo separating the granule from the vesicular limiting membrane, were identified as adrenaline cells.

Análise das manifestações auditivas em individuos com hipertensão arterial sistêmica

Objective: To determine the prevalence of auditory manifestations in individuals with hypertension and analyze the association between hearing loss, systemic hypertension and quality of life in hypertensive patients. Method: This was a prospective, observational, case-control study, carried out from June 2010 to December 2013 at the University Hospital Onofre Lopes, in Natal, Brazil, which involved 120 patients of both sexes were analyzed with a diagnosis of hypertension and 120 patients without a diagnosis of hypertension. The audiological function was assessed by tonal and vocal audiometry. The quality of life was defines by the MINICHAL BRASIL questionnaire. Results: The prevalence of hearing loss was high in both groups (82.5 % and 75.8 %, in hypertension group and control, respectively, p=0.003). The sensorineural was the most common type of hearing loss (48.5 %) in hypertension group while conductive hearing loss was predominant (61.5 %) in the control group. There were no difference in the intensity of hearing loss between the groups (p=0,21). The main hearing complaint was hearing loss (51 %), followed by ear pain (14 %). There was worse quality of life in hypertensive individuals with hearing loss (p= 0.0001). Conclusion: Hypertensive individuals showed higher prevalence of auditory events, including hearing loss, sensorineural hearing loss is predominant . Hearing loss is associated with worse quality of life of hypertensive individuals even when these pressure values are within normal limits

Interações comunicativas entre uma professora e um aluno com transtorno invasivo do desenvolvimento na escola regular

Inclusion of students with autism in regular education settings is a topic that has not been much explored by the national scientific literature. This matter is complex and, due to the extent of various aspects involved, it is essential to delimitate a focus of investigation. The direction taken by this study was to evaluate the effects of an intervention program in the communicative interactions between a student with autism and his teacher in a regular classroom. Data were collected in an elementary private school, located in the city of Natal, Rio Grande do Norte during the 2010 academic school year. The study included a teacher and a non-vocal, 10-year-old student diagnosed with autism. A quasi-experimental A-B research design was employed. During the intervention program the teacher was trained to use Naturalistic Teaching Strategies and Alternative and Augmentative Communication (AAC) resources to increase the frequency of interactions with the student during three classroom routines (entry time, snack and pedagogical activity). The results indicated qualitative and quantitative changes in the interactions of the dyad after the implementation of the intervention program. The student began to use pictograms to communicate with the teacher in two of the three routines investigated. The frequency of AAC use was also observed in the teacher‟s repertoire, especially when the student failed to understand gestures and words. The teacher positively evaluated the intervention program

Descrição anátomo-topográfica do coração da paca (Agouti paca)

Background: The domestic animals heart is a conical hollow viscera, surrounded by pericardium, laterally compressed, accompanying the thorax shape. Atriums constituted the heart basis and their auricles partially bound the initial portion of the aorta and pulmonary trunk. In mammals, heart is kept suspended in the thoracic cavity and the pericardic sac is fixed dorsally by great veins and arteries roots, and ventrally fixed to the sternum, although its fixation to the diaphragm varies among species. This paper aimed to describe morphological aspects of the heart of the paca, the second biggest Brazilian rodent.Materials, Methods & Results: There were used 12 hearts of adult pacas for this study, obtained from the UNESP, Jaboticabal, SP, which died due fights or anesthesia during bandages or radiograph exams. The thoracic aorta was filled with colored latex and the animal was set in a 10% formaldehyde solution for at least 72 hours. The thoracic cavity was dissected and hearts individualized and measured with a paquimeter, lateromedially, craniocaudally and dorsoventrally. The paca heart is placed between the first and fifth intercostal space (ICS), in a craniocaudal oblique position; its basis is craniodorsally positioned, on the middle third between the first and second ICS and its apex is located near the sternodiaphragmatic joint, on the fifth ICS, tilted to the left antimere. The heart is surrounded by pericardium, which from ventrocaudally is originated the sternopericardic ligament, that continues as phrenopericardic ligament. At the heart basis, the rising of the pulmonary trunk was observed and the conus arteriosus formed a typical projection. The aorta also rised from the heart basis and its arch, which was caudally curved, crossed dorsally the pulmonary trunk; the right cranial and caudal cava veins drained to the right atrium. There is a left cranial cava vein, which surrounded the left atrium and joined the right caudal cava vein on the right atrium. The azygos vein joins the right cranial cava vein and four pulmonary veins drained to the left atrium. At palpation, a hard structure on the rising of the aorta was observed, similarly to a cartilaginous tissue, which would be part of the cardiac skeleton. The left and right coronary arteries were observed in all hearts.Discussion: The paca heart is anatomica and topographically similar to those of domestic mammals, differing from them for being placed one intercostal space more cranial and due to the presence of two cranial cava veins, the left and the right ones, besides the presence of the caudal cava vein. This vascular description is similar to that of small rodents, as rats and mice. In paca heart, the sinus venous, the terminal crest, the oval fossa, the atrioventricular valvae, the papillary muscles and tendinous cords, besides smooth atriums and auricles covered by pectinate muscles, were observed. The sternopericardic ligament, which is dorsally elongated as phrenopericardic ligament, is similar to the one present in humans, pigs, castors, and different from the one observed in carnivorous, that presents the phrenopericardic ligament and from the one of horses and ruminants, which present the sternopericardic ligament.

Sistema inteligente para diagnóstico de patologias na laringe utilizando máquinas de vetor de suporte

The human voice is an important communication tool and any disorder of the voice can have profound implications for social and professional life of an individual. Techniques of digital signal processing have been used by acoustic analysis of vocal disorders caused by pathologies in the larynx, due to its simplicity and noninvasive nature. This work deals with the acoustic analysis of voice signals affected by pathologies in the larynx, specifically, edema, and nodules on the vocal folds. The purpose of this work is to develop a classification system of voices to help pre-diagnosis of pathologies in the larynx, as well as monitoring pharmacological treatments and after surgery. Linear Prediction Coefficients (LPC), Mel Frequency cepstral coefficients (MFCC) and the coefficients obtained through the Wavelet Packet Transform (WPT) are applied to extract relevant characteristics of the voice signal. For the classification task is used the Support Vector Machine (SVM), which aims to build optimal hyperplanes that maximize the margin of separation between the classes involved. The hyperplane generated is determined by the support vectors, which are subsets of points in these classes. According to the database used in this work, the results showed a good performance, with a hit rate of 98.46% for classification of normal and pathological voices in general, and 98.75% in the classification of diseases together: edema and nodules

Light microscopy and ultrastructure of the liver of Astyanax altiparanae Garutti and Britski, 2000 (Teleostei, Characidae).

Livers of thirty specimens of Astyanax altiparanae obtained from a commercial fish farm were subjected to light and transmission electron microscopy, in order to describe the hepatic parenchyma and the intrahepatic exocrine pancreatic tissue. Anatomically, the liver showed only three hepatic lobes. Histological analysis demonstrated that the hepatocytes were spread out as anastomotic cords, arranged in two cellular layers and surrounded by sinusoids. The intrahepatic exocrine pancreatic tissue exhibited an acinar arrangement and was diffused in the hepatic parenchyma. Ultrastructural analysis showed that the hepatocytes had a rounded nucleus and a rough endoplasmatic reticulum, with a parallel disposition to the nuclear membrane. The exocrine pancreatic cells showed secretion granules at the apical portion, and the rough endosplasmatic reticulum was concentrically distributed.
