A Música Coral dos Primórdios do Século XX aos Primórdios do Século XXI: a Composição para Coros e a Performance do Repertório Moderno/Contemporâne

This paper is a small part of my Doctoral dissertation which is a large study about the practice and sonority in various choral music styles. Focusing on the choral music from the beginning of the 20th century to the present day, and based upon a bibliographical review, this article describes the characteristics of the choral composition and reflects on the performance aspects of the performance of modern and contemporary choral repertoire such as vocal tone color, intonation and non-traditional vocal techniques.

Aquecimento vocal para o canto erudito: teoria e prática

Vocal warm-ups are essential for the technical training of the singer, for good speech and performance, as well as essential for good vocal health and a long-lasting career. Objective: To analyze the theory and practice of the vocal warm-up in classical singing, from the perspective of different professionals in the voice field including: teachers, speech therapists and singers. Method: descriptive search, quantitative in nature, cross-sectional, with a questionnaire for voice teachers, singers and audiologists. The sample consisted of 165 subjects: 86 voice teachers, 64 speech pathologists, and 15 singers. Results: Teachers of Singing (97.7 %), singers (95.3 %) and students (93.3 %) use the vocal warm-up. Conclusion: From the results we can infer that most of the professionals surveyed point to the importance of the implementation of the vocal warm-up before a performance, and the strategy used by most voice instructors, speech therapists and singers is vocalization, i.e. aesthetic warm-up.

Obras para voz y piano de Honorio Siccardi : música argentina del siglo XX

Con la edición del presente trabajo entregamos a los estudiosos de la historia de la Música Argentina del Siglo XX, recopilación y digitalización de obras para voz y piano del compositor Honorio Mario Siccardi (1897-1963). Cabe mencionar que este trabajo se inicia en el año 2005 a partir del proyecto de investigación: “Música Argentina del Siglo XX. Obras para voz y piano de Honorio Siccardi", subsidiado por Secretaría de Ciencia, Técnica y Posgrado de la Universidad Nacional de Cuyo y continúa con mi tema de Tesis: “Obras para voz y piano de Honorio Siccardi: una aproximación analítica", en la Maestría en Arte Latinoamericano, defendida en marzo de 2009[418 páginas], en la misma Universidad. La documentación es relevada del archivo personal del compositor, situado en la Ciudad de Dolores en la provincia de Buenos Aires, el cual está bajo la supervisión y cuidado de su hijo Héctor Siccardi. Las partituras publicadas, con el consentimiento de las editoriales citadas y los herederos habientes, están agotadas (casi en su totalidad) o de difícil acceso, por lo tanto han sido incorporadas en este trabajo para completar el total de obras para voz y piano del compositor. El trabajo de digitalización de los manuscritos de las obras presentadas es realizado por las profesoras Verónica Cortes (Nº 4, 6, 7, 8, 9, 12, 16), María Emilia Greco (Nº 2, 3, 15, 17, 18, 19, 20, 21, 22 y 23) y Natacha Sánchez (Nº 1 y correcciones generales), integrantes del proyecto mencionado, egresadas y docentes de la Facultad de Artes y Diseño de la Universidad Nacional de Cuyo.

A Reeducação Postural Global (RPG) e as Autoposturas Respiratórias de Philippe Souchard, implicações na prática vocal/coral

A Investigação científica que se apresenta enquadra-se no âmbito do Projeto Educativo, integrado no Mestrado em Ensino da Música, especialidade em Música de Conjunto, realizado no Conservatório Superior de Música de Gaia (CSMG). Esta Investigação-ação, de análise qualitativa, centrou-se na implementação de um Programa de Intervenção: A Reeducação Postural Global (RPG) e As Autoposturas Respiratórias, na Produção Sonora Musical no Canto (Philippe Souchard, 1987; 1997; 2011). Assente no modelo de Relação Pedagógica (RP) de Renald Legendre (2005), teve como Sujeitos (S) de aprendizagem dois grupos das Classes de Conjunto de Coro, da Fundação Conservatório de Música de Gaia: o Grupo de Ação (GA) e o Grupo de Controlo (GC). Aplicadas sessões de fisioterapia ao GA, ambos os grupos interpretaram a Obra Coral Pange Lingua, de Zoltán Kodály. Pelos registos apresentados na análise de dados, ditos em diários de bordo dos Sujeitos (S) e do Agente (A) professor da Classe de Conjunto, e em imagens fílmicas e fotográficas realizadas, verificamos a eficácia deste Programa. À luz dos exercícios da Reeducação Postural Global (RPG) e das Autoposturas Respiratórias, de Philippe Souchard, aplicados ao estudo da obra mencionada, pudemos verificar que os Sujeitos (S) do Grupo de Ação apresentaram progressos vocais de significativa importância.

Anatomical Study Of Minor Alterations In Neonate Vocal Folds.

Minor structural alterations of the vocal fold cover are frequent causes of voice abnormalities. They may be difficult to diagnose, and are expressed in different manners. Cases of intracordal cysts, sulcus vocalis, mucosal bridge, and laryngeal micro-diaphragm form the group of minor structural alterations of the vocal fold cover investigated in the present study. The etiopathogenesis and epidemiology of these alterations are poorly known. To evaluate the existence and anatomical characterization of minor structural alterations in the vocal folds of newborns. 56 larynxes excised from neonates of both genders were studied. They were examined fresh, or defrosted after conservation via freezing, under a microscope at magnifications of 25× and 40×. The vocal folds were inspected and palpated by two examiners, with the aim of finding minor structural alterations similar to those described classically, and other undetermined minor structural alterations. Larynges presenting abnormalities were submitted to histological examination. Six cases of abnormalities were found in different larynges: one (1.79%) compatible with a sulcus vocalis and five (8.93%) compatible with a laryngeal micro-diaphragm. No cases of cysts or mucosal bridges were found. The observed abnormalities had characteristics similar to those described in other age groups. Abnormalities similar to sulcus vocalis or micro-diaphragm may be present at birth.

Efeito da associação de sabor e música sobre o estado de ânimo de crianças

Este estudo teve como objetivo avaliar como sabor e música exercem efeito sobre o estado de ânimo de crianças. Participaram 83 crianças de 5 a 10 anos de idade e de ambos os sexos. A tarefa dos participantes consistiu em experimentar o sabor de soluções doce e amarga na ausência de música e na presença de músicas pré-qualificadas como alegres e tristes, e depois, julgar o estado de ânimo decorrente da experimentação. O julgamento do estado de ânimo das crianças se modificou quando o sabor era amargo e as músicas eram alegres, caso em que o estado de ânimo se alterou de triste para alegre; quando o sabor era doce e as músicas tristes, o estado de ânimo passou de alegre para triste. Futuros trabalhos podem observar crianças realizando tarefas que apresentem contextos de alimentos reais associados à estimulação musical.

The effect of hearing impairment on the vocal characteristics of older people

Measures of vocal intensity, frequency and harshness were compared for 19 hearing-impaired and 21 normal-hearing people over 60 years of age. Significantly greater comfortable intensity levels were found in the hearing-impaired group, but the other measures of frequency and harshness were not significantly different. A large proportion of the subjects in both groups reported a history of gastro-oesophageal reflux (GER), a condition associated with vocal fold pathology and hoarseness. Comparison of the GER and non-GER subjects on the measures of vocal function showed that the female GER speaker exhibited lower frequency on the vowel /u/ than the non-GER subjects. Clinicians need to be aware of the effect of highly prevalent disorders such as hearing impairment and GER on the voices of elderly speakers.

Histologic Study of Perifascial Areolar Tissue Implanted in Rabbit Vocal Folds: An Experimental Study

Objectives: Perifascial areolar tissue (PAT) consists of loose areolar tissue with viscoelastic properties that are similar to those found in tissues in the superficial layer of the vocal fold. The aim of this study was to quantify the inflammatory process and the collagen content of the graft, as well as that of the host tissue, after placement of a strip of PAT into the rabbit vocal fold. Methods: Surgeries were performed on 30 rabbits. The grafts were implanted in pockets that were surgically created in the right vocal fold. The left vocal fold (control group) was subjected only to surgical manipulation. The animals were divided into 3 groups for evaluations at 15 days, 3 months, and 6 months, and their larynx tissues were subsequently reviewed by histology. Results: The grafts were characterized by disorganized and thick collagen bundles and were identified in all study groups. The collagen density stayed constant over time. There was an acute inflammatory response induced by the graft at 15 clays that did not exist in the specimens taken at 3 and 6 months. Deposition of collagen fibers in the lamina propria was observed starting at 15 days after the operation and was more intense in the experimental vocal fold than in the control vocal fold. Conclusions: Our findings indicated that PAT has a low tendency for promoting an inflammatory response. However, there was a loss of the original architecture of the graft tissue and a greater deposition of collagen in the implanted vocal folds than in the control group.

Vocal Symptoms in Telemarketers: A Random and Controlled Field Trial

The present study was carried out to evaluate the effectiveness of a specific program regarding the occurrence of vocal attrition symptoms in telemarketers. A total of 71 subjects participated in this study: 28 completed the Vocal Symptoms questionnaire to test its reliability, and 43 were randomly assigned to two groups: an 8-week vocal training group (n = 14) and a no-training control group (n = 29), to evaluate the effectiveness of the training program with this tool. The voice training group also filled in the posttraining questionnaire `Benefits Obtained with Voice Training` (BVT). The vocal training program was not considered effective with regard to the occurrence of vocal symptoms. However, due to a probable increase in symptoms in untrained telemarketers, it can work as a protective factor. According to BVT answers, the vocal training contributed to an improvement in vocal use as a communication tool for telemarketers. Copyright (C) 2009 S. Karger AG, Basel

Collagen Type I, Collagen Type III, and Versican in Vocal Fold Lamina Propria

Objective: To analyze the distributions of collagen type I, collagen type III, and versican in the lamina propria of the human vocal fold. Design: Cross-sectional analysis of cadaveric vocal folds of adult human larynges. Setting: Academic tertiary referral center. Subjects: Larynges harvested at autopsy from 10 adult men and 10 adult women. Main Outcome Measures: Immunohistochemical reactions were performed using antihuman monoclonal antibodies to analyze the expression of collagen type I, collagen type III, and versican. Results: Collagen type I density was lower in the intermediate layer compared with the superficial and deep layers of vocal folds. Collagen type III density was lower in the intermediate layer compared with the deep layer. Versican density was lower in the superficial layer compared with the intermediate and deep layers. Versican density was lower in the lamina propria of women compared with men; this difference was noted in the superficial layer only. There was a positive correlation between collagen type III and versican densities within the lamina propria. Conclusion: Collagen type I, collagen type III, and versican are distributed differently within the lamina propria layers of the adult vocal folds.

Collagen Fiber and Versican Distribution Within the Lamina Propria of Fetal Vocal Folds

Objectives: To analyze the presence and distribution of collagen fibers and versican in human vocal fold lamina propria of fetal larynges. Study Design: Cross sectional analysis of cadaveric vocal folds of human fetuses. Methods: Seven fetal larynges obtained from 28- to 36-week-old fetuses were analyzed with the Picrosirius-polarization method, immunohistochemistry, and image analysis. Results: Collagen fibers within the lamina propria exhibited a monolaminar distribution pattern and spatial arrangement in ""wicker basket."" Versican distribution was larger in the superficial and intermediate layers when compared to the deep layer. Conclusion: Our findings suggest that collagen and versican distribution and arrangement within the lamina propria in the developing fetus are important for vocalization at birth.
