Thesis (MDram)--University of Stellenbosch, 2008. / In a study of Kristin Linklater’s approach to voice training the concept of the natural voice and the freeing of it stands central. The natural voice according to Linklater is that voice which is naturally produced by the voice-organs without any restrictions that can inhibit it and thus have a maximum potential for the use during speech/work. The opposite to the natural voice is the unnatural voice, which can be described as the production of speech in such a manner that it is restricted or inhibited by conscious or unconscious means. Linklater’s approach focuses on the recognition of the natural voice and the freeing it from negative habits. Her freeing theory with regards to the natural voice consists of the junction of the acknowledgment of physical and psychological habits in the body with the aim of strengthening the natural voice and not only to teach new vocal techniques and habits. The process of freeing the natural voice consists of recognizing and eliminating negative speech and voice related habits. Linklater’s approach to voice training is not unique. The approaches of the other voice theoreticians such as Berry, Rodenburg, Houseman and Lessac have the same kind of approach to voice training (wich includes the concept of the natural voice). Al though some differences occur in connection to their approaches to the roots of habits and the conditioning of voice habits and the eventual freeing of the natural voice through unlearning of the habits that suppress the natural voice.

Esse estudo investigou os efeitos imediatos da TENS, TENS placebo, TENS e Lax Vox e TENS placebo e Lax Vox nos sintomas vocais, laríngeos e de dor, bem como na qualidade vocal e na atividade muscular de mulheres disfônicas e comparou essas etapas de intervenção. Participaram 10 mulheres (18 a 45 anos), com disfonia comportamental. Todas realizaram quatro etapas de intervenção randomizadas: TENS (200 s, 10 Hz, limiar motor, 20 minutos, eletrodos bilaterais: região submandibular e trapézio-fibras descendentes); TENS placebo (mesmas condições que TENS; aparelho em mínima intensidade); TENS e Lax Vox (após TENS, dez minutos de sopro sonorizado com Lax Vox - pitch habitual e glissando ascendente) e TENS placebo e Lax Vox. Antes e após cada etapa foram realizadas avaliações: questionários sobre intensidade de sintomas vocais/laríngeos/dor, gravação vocal (/a/, contagem) e eletromiografia de superfície dos músculos trapézio-fibras descendentes (TFD), esternocleidomastóideos (ECM), infra-hióideos e supra-hióideos. Após a TENS houve diminuição da intensidade da maioria dos sintomas, tanto quanto após TENS e Lax Vox. Porém, somente após a TENS houve melhora da dor ao falar (p=0,027) e ao engolir (p=0,020). A TENS reduziu intensidade dos sintomas pigarro (p=0,050) e falhas na voz (p=0,020) assim como TENS e Lax Vox; também houve melhora de: pigarro (p=0,010) e falhas na voz (p=0,020). Após a TENS placebo e Lax Vox houve diminuição da intensidade de grande parte dos sintomas e de voz grossa (p=0,035) e tosse seca (p=0,012), esses últimos também após TENS e Lax Vox (p=0,036; p=0,018, respectivamente). A TENS diminuiu a intensidade de dor nos ombros (p=0,041), parte superior das costas (p=0,032) e temporal (p=0,035), como as demais etapas. A TENS placebo reduziu a intensidade de dor de muitas regiões corporais. Após TENS placebo e Lax Vox houve diminuição da intensidade de dor da maior parte das regiões corporais, inclusive laringe (p=0,028). Após TENS placebo e Lax Vox, houve melhora de 40% do grau geral da qualidade vocal (/a/), após TENS e Lax Vox, de 50% (contagem). A análise acústica revelou aumento do jitter (p=0,009) e variação da frequência fundamental (p=0,012) após TENS placebo. A eletromiografia revelou aumento da atividade elétrica após TENS no ECM direito no repouso (p=0,036); aumento da atividade no TFD esquerdo na contagem (p=0,046) após TENS placebo e Lax Vox. Na comparação entre etapas, a TENS associada à Lax Vox diminuiu a atividade elétrica no TFD esquerdo, enquanto TENS placebo e Lax Vox, aumentou (p=0,045) na contagem; na vogal /a/ a TENS placebo associada à Lax Vox diminuiu a atividade elétrica para TFD esquerdo, enquanto que a TENS aumentou (p=0,040); a TENS placebo foi a etapa que mais diminuiu a atividade elétrica no repouso, em comparação com: TENS e Lax Vox e TENS (p=0,015). Como conclusão, a TENS e Lax Vox e a TENS placebo e Lax Vox trouxeram mais benefícios. Apenas uma aplicação das etapas de intervenção fonoaudiológica não atuou de forma homogênea sobre as características da atividade elétrica dos músculos avaliados. / This study investigated the immediate effects of TENS, placebo TENS, TENS and Lax Vox and placebo and Lax Vox TENS on vocal, laryngeal and pain symptoms, as well as vocal quality and muscle activity of dysphonic women and compared these intervention steps. Participated 10 women (from 18 to 45 years old), with behavioral dysphonia. All performed four randomized intervention steps: TENS (200 s, 10 Hz, motor threshold, 20 minutes, bilateral electrodes: submandibular region and trapezoid-downward fibers); TENS placebo (same conditions as TENS; apparatus in minimal intensity); TENS and Lax Vox (after TENS, ten minutes of blowing sound with Lax Vox - usual pitch and upward bass to treble variation) and TENS placebo and Lax Vox. Before and after each stage, evaluations were performed: questionnaires on intensity of vocal/laryngeal symptoms/pain, vocal recording (/a/, counting) and surface electromyography of the trapezius-descending fibers (PDT), sternocleidomastoid (ECM) Hyoids and supra-hyoids. After TENS there was a decrease in the intensity of most symptoms as much as after TENS and Lax Vox. However, only after the TENS there was an reduction in pain when speaking (p=0.027) and swallowing (p=0.020). The TENS reduced the intensity of the choking symptoms (p=0.050) and speech failures (p=0.020) as well as TENS and Lax Vox; there was also reduction of: clearing (p=0.010) and voice failures (p=0.020). After TENS, placebo and Lax Vox, there was a decrease in the intensity of a large number of symptoms, including low voice (p=0.035) and dry cough (p=0.012), also these last ones after TENS and Lax Vox (p=0.036; p = 0.018, respectively). The TENS decreased the intensity of pain in the shoulders (p=0.041), upper back (p=0.032) and temporal (p=0.035), as the other stages. TENS placebo reduced the pain intensity of many body parts. After TENS, placebo and Lax Vox, there was a decrease in pain intensity of the most body parts, including larynx (p = 0.028). After placebo TENS and Lax Vox, there was improvement of 40% of the general degree of vocal quality (/a/), after TENS and Lax Vox, of 50% (counting). The acoustic analysis revealed increased of the jitter (p=0.009) and the fundamental frequency variation (p=0.012) after placebo TENS. Electromyography revealed electrical activity increasing after TENS in the right ECM at rest (p=0.036); Increased activity in the left PDT at the count (p=0.046) after placebo TENS and Lax Vox. In the comparison between steps, TENS associated to Lax Vox the electrical activity, reduced the left PDT, while TENS placebo and Lax Vox increased (p=0.045) in the counting; in the /a/ vowel the placebo TENS associated to Lax Vox reduced the electrical activity for left PDT, whereas the TENS increased (p=0.040). The TENS placebo was the stage that had the biggest electrical activity decreasing at rest, compared with: TENS and Lax Vox and TENS (p=0.015). As a conclusion, both associations, TENS combined whit Lax Vox and TENS placebo combined with Lax Vox brought more benefits than the other methods tested (isolated TENS and placebo TENS). Only one application of the phonoaudiological intervention steps did not act homogeneously on the characteristics of the electrical activity of the evaluated muscles.

Summary Objectives/Hypotheses To assess the utility of a targeted voice hygiene (VH) program compared to VH plus voice training intervention (VH+VT) for the prevention and treatment of voice problems in student teachers. Study Design Prospective, randomized. Methods Thirty-one student teachers with low (good) and high (poor) voice handicap index (VHI) scores in Pittsburgh and Hong Kong were randomly assigned to (1) a targeted, individually tailored VH program, (2) the VH program plus resonant VT (VH+VT), or (c) a control group. Participants assigned to intervention groups were monitored for their adherence to their programs for their first 4 weeks of student teaching. VHI data were collected again 4 weeks postintervention (both sites) and 8 weeks postintervention, following a no-contact washout period (Pittsburgh). Results Descriptive data analysis indicated that across both sites, for initially healthy participants, the VH program was sufficient to prevent worsening of VHI scores that occurred in all control participants over the first 4–8 weeks of student teaching. The addition of VT did not consistently enhance protective benefits over VH alone. In contrast, for participants with initially poor VHI scores, the VH program failed to produce VHI benefits over the control condition. The addition of VT was required to optimize results for that cohort. Conclusions Preliminary data suggest that a minimalist, individually tailored VH program may be sufficient to prevent voice problems from teaching in healthy student teachers. However, for student teachers with existing voice problems, VT may be required to optimize results of intervention.

<p>In Sweden surgical treatment of vocal fold lesions in children is fairly uncommon. At Falun hospital they have adapted a more generous attitude towards phonosurgery of children’s vocal folds. The purpose of the present study was to evaluate surgical treatment of organic vocal fold lesions in children and to assess the phonosurgical patient utility. The study was carried out at the Ear-, Nose- and Throat clinic, Falun hospital, Sweden. Based on case sheets, data was collected regarding the different vocal fold lesions that were surgically treated. The most frequent vocal fold abnormalities were vocal fold nodules, vocal fold cysts and sulcus/vergeture. Further on, assessment of pre- and postoperative voice recordings and stroboscopic examinations were carried out. The general tendency was that vocal fold closure and mucosal wave was estimated as normal or less abnormal following surgery in most patients. Postoperatively, hoarseness, breathiness and roughness were estimated to be significantly lower. For hyperfunction, only a tendency to lower occurrence was observed. The estimation of high pitch was similar pre- and postoperatively. A mail questionnaire showed that most patients/parents estimated a high degree of perceived voice related problems preoperatively. Most patients rated their own vocal function at the time of the study as highly functional. The majority were satisfied with the choice of undergoing surgical treatment. The conclusion was that surgical treatment may be a good option in organic vocal fold lesions in children.</p> / <p>I Sverige är kirurgisk behandling vid stämbandsförändringar hos barn relativt ovanligt.

Vidare genomfördes bedömning av pre- och postoperativa röstinspelningar och stroboskopiska undersökningar. Den generella tendensen var att stämbandsslutning och slemhinnevåg i större utsträckning skattades normal eller mindre avvikande efter operation i jämförelse med före operation. Förekomst av röstparametrarna heshet, läckage och skrovlighet bedömdes vara signifikant lägre efter kirurgi. För press kunde endast tendens till lägre förekomst observeras medan det generellt höga röstläget skattades lika före och efter operation. Genom en enkät framkom att flertalet patienter/patienters målsmän skattade förhållandevis höga värden av upplevda röstbesvär före operation. Flertalet skattade höga värden angående hur väl rösten fungerade vid studiens genomförande. Majoriteten var nöjd med valet att genomgå operation. Slutsatsen var att kirurgisk behandling kan vara ett bra behandlingsalternativ vid organiska stämbandsförändringar hos barn.</p>

Diagnostic and evaluative methods used in voice care are mostly designedfor the speaking voice, and are not necessarily directly applicable to thesinging voice. This thesis investigated the possibilities of fine tuning, improvingand quantifying the voice status assessment of the singer, focusingespecially on the Western operatic female voice. In Paper I, possible singer-specific Voice Range Profile (VRP) characteristicsand tasks were explored and VRP data for 30 professional female Western opera singers was collected. Vocal productions were controlled for a physiological VRP (VRPphys) and for a stage performance context (VRPperf) and outcome differences were identified. Task design was critical for the(VRPphys) but had very little effect on the VRPperf. Significant voice category differences (between soprano,mezzo-soprano and contralto) were limited to frequencyrelated metrics. Two new VRP metrics, the area above 90 dB (Perc90dB) and the sound pressure level extent (SPLext), were found to be key metrics to the study of VRPs for singers. Paper II investigated, in conjunction with the VRP, whether the sound pressure level (SPL) or the skin acceleration level (SAL) was more correlated to the subglottal pressure (Ps). SAL was much less F0 dependent than SPL and facilitated the interpretation of VRP data. However, the correlation between SAL and Ps was found to be weaker than that between SPL and Ps. Papers III and IV explored the mapping of self-perceived impairmentrelated difficulties into the VRP. A modified phonetograph was tested first with a healthy singer population and then with a singer-patient group. Subjects used a button device to communicate their self-perceptions while singing, and were consistent in task replications as well as across different tasks. Healthy singers pressed mostly at the extreme limits of the VRP, where loss of vocal control could be expected and their presses were mostly concentrated on the periphery of the VRP area. Singer patient button- press patterns were distinct from patterns observed in healthy singers. Singer patients pressed mainly inside the VRP boundaries, in the higher range and at intermediate intensities. In Paper V, the Voice Handicap Index for singers was translated and adapted to Swedish (Röst Handikap Index för sångare or RHI-s). The questionnaire was found to be a reliable and a valid instrument. High correlations between general perceptual patient VAS ratings and the questionnaire scores underscored the instrument’s internal coherence. Overall, patient scores (including subscales) were significantly higher than healthy singer scores. The results showed implicitly the necessity and usefulness of adapting clinical procedures to specific patient populations.Together, the results of these five papers can ultimately be of value tovoice clinicians who are treating singers. The results obtained also contributeto the understanding of the singing voice and underline the importance ofproperly documenting the singing voice. / QC 20100726

L’objectiu d’aquesta recerca és conèixer l’eficàcia d’un curs de prevenció dels trastorns de la veu adreçat a docents en actiu. Per fer-ho s’ha dut a terme un estudi longitudinal amb disseny pre-test i post-test amb grup control i grup experimental i, alhora, un estudi transversal per comparativa de grups. S’han realitzat un total de 3 avaluacions: la primera en iniciar-se el curs (pre-test), una avaluació just en finalitzar el curs (per conèixer l’eficàcia del curs a curt termini) i una darrera avaluació sis mesos més tard (mig termini). Seguint les recomanacions de la ELS, s’ha fet una avaluació multidimensional de la veu incloent: una anàlisi de la qualitat vocal objectiva a través del DSI (Wuyts et al., 2000), una anàlisi de la qualitat vocal perceptiva valorada amb l’ítem global del GRBAS (la G) (Hirano, 1981), una valoració de la percepció de l’handicap vocal avaluada amb el VHI- 10 (Jacobson et al., 1997; Nuñet-Batalla et al., 2007) i una valoració dels coneixements relatius a la funció vocal estimats amb el qüestionari COFUVO, elaborat expressament per aquesta recerca. També s’han recollit algunes dades sociodemogràfiques dels subjectes i un qüestionari d’opinió sobre la tasca docent del formador. Els resultats registrats han mostrat que l’adquisició de coneixements teòrics, estimats amb el qüestionari COFUVO, s’assoleixen ràpidament. Aquests coneixements semblen mantenir-se a mig termini, quan també s’observen canvis significatius en la qualitat vocal objectiva dels docents participants al curs, mitjançant l’índex DSI. Ens qüestionem, però, si aquest índex valora la qualitat vocal objectiva o les habilitats vocals dels participants. Ni el VHI-10, ni el paràmetre global del GRBAS mostren diferències significatives entre els tests ni els grups. Finalment, les diferències observades segons el formador responsable del curs plantegen la necessitat de controlar aquesta variable. En conseqüència, podem confirmar que el curs ha permès millorar les habilitats vocals dels docents així com els seus coneixements sobre el fenomen vocal a mig termini. Per tal de conèixer els beneficis arran del curs sobre la qualitat i la salut vocal dels docents seria interessant plantejar un estudi a més llarg termini. / El objetivo de la presente investigación es conocer la eficacia de un curso de prevención de los trastornos de la voz, dirigido a docentes en activo. Para ello se ha realizado un estudio longitudinal con un diseño pre-test y post-test con grupo control y grupo experimental y, a su vez, un estudio transversal por comparativa de grupos. Se han realizado un total de 3 evaluaciones: la primera al iniciarse el curso (pre-test), una evaluación justo en finalizar el curso (para conocer la eficacia del curso a corto plazo) y una ultima evaluación seis meses mas tarde (largo plazo). Siguiendo las recomendaciones de la ELS, se ha realizado una evaluación multidimensional de la voz incluyendo: un análisis de la calidad vocal objetiva con el índice DSI (Wuyts et al., 2000), un análisis de la calidad vocal perceptiva valorada con el parámetro global del GRBAS (la G) (Hirano, 1981), una valoración de la percepción del hándicap vocal evaluada con el VHI-10 (Jacobson et al., 1997; Nuñet-Batalla et al., 2007) y una evaluación de los conocimientos relativos a la función vocal estimados con el cuestionario COFUVO, elaborada a propósito de esta investigación. También se han recogido algunos datos sociodemográficos de los sujetos y un cuestionario de opinión sobre la tarea docente del formador. Los resultados registrados han mostrado que la adquisición de conocimientos teóricos, estimados con el cuestionario COFUVO, se asumen rápidamente. Estos conocimientos parecen mantenerse a medio plazo, cuando también se observan cambios significativos en la calidad vocal objetiva de los docentes participantes al curso, mediante el DSI. Nos cuestionamos, sin embargo, si este índice valora la calidad vocal objetiva o las habilidades vocales de los participantes. Ni el VHI-10, ni el parámetro global del GRBAS muestran diferencias significativas entre los test y los grupos. Finalmente, las diferencias observadas en relación al formador responsable del curso plantean la necesidad de controlar esta variable. En consecuencia, podemos afirmar que el curso ha permitido mejorar las habilidades vocales de los docentes y sus conocimientos sobre el fenómeno vocal a medio plazo. Para conocer los beneficios sobre la calidad y la salud vocal de los docentes seria interesante plantear un estudio a más largo plazo. / The objective of this research is to find out how effective a voice disorder prevention course addressed to teachers is. In order to do so, a program has been designed with pre- test and post-test actions, and a control group and an experimental group, plus, at the same time, a comparative survey of the groups. There have been three assessments: the first one when the course started (pre-test), another one right at the end (to find out how effective the course is on a short term basis), and a last assessment six months later (medium-term). Following recommendations from the ELS, a multidimensional assessment of the voice has taken place including: analysis of voice objective quality through DSI, (Wuyts et al., 2000), an analysis of voice perceptive quality assessed with GRBAS global item (the G) (Hirano, 1981), an assessment of the perception of voice handicap valued with VHI-10 (Jacobson et al., 1997; Nuñet-Batalla et al., 2007) and an assessment of relative knowledge to voice function estimated with the COFUVO questionnaire, elaborated just for this test. Also, some sociodemographic data of the subjects has been gathered, including an opinion questionnaire about the teacher. The results have shown that theoretical knowledge, estimated with the COFUVO questionnaire, is achieved quickly. This knowledge seems to be retained at medium- term, when also significant changes can be observed in the vocal objective quality of the teachers taking the course, through the DSI index. However, we question whether this index is assessing the vocal objective quality or the vocal skills of the participants. Neither VHI-10 nor global parameters of the GRBAS show significant differences between tests or groups. Finally, the differences observed according to the teacher responsible for the course indicate the need to control this variable. Consequently, we can confirm that the course has meant an improvement in the vocal skills of the teachers as well as their knowledge of the voice phenomenon at medium- term. A longer term study would be recommended to learn more about the benefits of voice health and quality of teaching staff following the course.

The present research, thus, claims that the common feature of these constructions is the non-attribution of causality, and that they represent different event conceptualizations. Based on principles, founded on a cognitive-functional approach (GIVÓN, 1993, 1995, 2002, 2005; KEMMER, 1993; CAMACHO, 2002, 2003, 2006; HOPPER & THOMPSON, 1980; POTTIER, 1992; CROFT, 1994, 1998; LANGACKER, 1987, 1991; DELANCEY, 1987; TALMY, 1988, 2000; LAKOFF, 1977), the codification of the non-attribution of causality is analyzed in Crônica Geral de Espanha de 1344, a representative historical text in archaic Portuguese, edited by Cintra (1951). In this analysis, answers are sought for the following questions: (a) in the analyzed corpus, which is the most and the least prototypical verbal recourses available for the expression of the non-attribution of causality? (b) which semantic, pragmatical and formal features characterize the different strategies used for expressing the non-attribution of causality? The central hypothesis considers that analyzed constructions codify the non-attribution of causality at various degrees, according to aspects related to the causality notion, such as perspectivization and salience. A large number of occurrences (1061, in total) were collected and analyzed from the perspective of pragmatical aspects such as topicality and informational status; semantic aspects, such as cognitive salience of Affected and of Causative, animacy, affectation type; and formal aspects, such as order and expression. Moreover, all of such occurrences were graduated regarding the transitivity degree and the Grounding. The results indicate that middle construction is the most prototypical of the non-attribution of causality constructions, because it presents less salient causative and is posited in the least degree of transitivity. Passive, most frequent in the corpus and, often, with omitted causative, was characterized as the least prototypical construction because its causative is commonly evoked and it presents a higher degree of transitivity. Impersonal construction, whose causative is frequently inferable, was characterized as more causative and more transitive than the middle construction, however, less than passive. Therefore, the analyses demonstrated that non-attribution of causality is not an isolated phenomenon, limited to the manifestation of an Agent. It is subject to degrees of escalarization which is attached to temporal and aspectual event contours. Because of experiential notion of causality, linked to the idea movement, perfective events are more causal than imperfective ones / Este trabalho visa caracterizar formal, semântica e pragmaticamente as construções passivas, médias e impessoais, com o fim de elucidar a natureza da relação entre estas construções, no português arcaico, relação essa observada em trabalhos, como os de Camacho (2002, 2003, 2006), para o português atual. Parte do princípio de que o traço comum a essas construções é a não-atribuição de causalidade, e de que estas construções refletem diferentes conceitualizações de um evento. Com base nesses princípios, analisa, numa abordagem cognitivo-funcional (GIVÓN, 1993, 1995, 2002, 2005; KEMMER, 1993; CAMACHO, 2002, 2003; HOPPER & THOMPSON, 1980; POTTIER, 1992; CROFT, 1994, 1998; LANGACKER, 1987, 1991; DELANCEY, 1987; TALMY, 1988, 2000; LAKOFF, 1977), a codificação da função não-atribuição de causalidade na Crônica Geral da Espanha de 1344, prosa histórica representante do português arcaico, editada por Cintra (1951). Nessa análise, busca respostas para os seguintes problemas: (a) dos recursos verbais disponíveis, no corpus analisado, para a expressão da não-atribuição de causalidade, qual a mais e a menos prototípica? (b) que traços semântico-pragmáticos e formais caracterizam as diferentes estratégias? A hipótese central considera que as construções analisadas codificam a não-atribuição da causalidade em variados graus, conforme fatores ligados à noção de causalidade e à transitividade, como a perspectivação e a saliência. Foram coletadas 1061 ocorrências e analisadas quanto a fatores pragmáticos, como a topicalidade e o estatuto informacional; fatores semânticos, como saliência cognitiva do Afetado e do Causativo, traço [animado], tipo de afetação; e fatores formais, como a ordem e a expressão. Além disso, todas foram graduadas quanto ao grau de transitividade e de relevo discursivo. Os resultados apontaram que a média é a mais prototípica das construções de não-atribuição de causalidade, por ser a que apresenta causativo menos saliente e menor grau de transitividade. A passiva, mais freqüente no corpus e, muitas vezes, com Causativo omitido, caracterizou-se como menos prototípica por seu Causativo ser freqüentemente evocado e apresentar maior grau de transitividade. Do mesmo modo, a impessoal, cujo causativo é freqüentemente inferível, manifestou-se como mais causativa e mais transitiva que a média, todavia menos que a passiva. A análise demonstrou, enfim, que o fenômeno da não-atribuição de causalidade não é um fenômeno isolado, limitado à manifestação ou não de um Agente. Submete-se a graus e acha-se ligado, especialmente, ao contorno têmporo-aspectual do evento. Devido à noção experiencial de causalidade, ligada à idéia de movimento, eventos perfectivos são mais causais que eventos imperfectivos

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This chant-dissertation is the sharing of my reflection on the theme of the sacred dimension of poetic voice, done through dialogue and intersection of two research fields. The first field is the work of Cecilia Valentim in her approach A Arte do Ser Cantante and the second one is the creation process the play Recusa, by Cia Balagan , where I frame the research on the vocal poetic work developed, both fields are mainly located in São Paulo. To thicken the discussion on the theme voice and sacred, I bring the concepts discussed by Grotowski, a great theater thinker, about the presence of the actor, Art as Vehicle and vibration chants, as well as other references related to voice, rituality, singing, creation. In order to accomplish this research I use semi-structured interviews and field journals. For the first field I followed a number of courses given by Cecília Valentim. As for the second field, the analysis was done through the play´s appreciation and the reading of several materials from the process (film, images, articles written about the process, etc). From contact with the two fields of research some elements emerged which guided me through the reflection on the subject of voice and the sacred. The identification and formulation of such elements are my place of arrival in the investigation. I build through the research a thought about voice as humanity force, as discovery and expansion of oneself and of the world. / Este canto-dissertação é o compartilhamento de minha reflexão sobre o tema da dimensão sagrada da voz poética, feita através da análise e diálogo com dois campos de pesquisa, localizados em São Paulo. O primeiro deles é o trabalho de Cecília Valentim na sua abordagem A Arte do Ser Cantante, e o segundo campo é o processo de criação do espetáculo Recusa, da Cia Teatro Balagan, sob o recorte do trabalho poético vocal desenvolvido. Para adensar a discussão sobre a voz e o sagrado trago conceitos elaborados por Grotowski sobre a presença do ator, a Arte como Veículo e os cantos vibratórios, bem como outras referências relacionadas à voz, ritualidade, canto, criação. Em ambos os contextos realizo entrevistas semiestruturadas e registro em diário de campo. No caso do primeiro campo, ainda acompanho cursos livres e formação ministrada por Cecília Valentim. Para a análise do processo de Recusa parto da fruição do espetáculo e leitura de materiais (vídeo, imagens, artigos sobre o processo de criação, etc). A partir do contato com os dois campos emergem alguns elementos que me conduziram no pensamento sobre o tema da voz e do sagrado. A identificação e a formulação de tais elementos são meu lugar de chegada na investigação. Construo a partir da pesquisa uma reflexão sobre a voz como força de humanidade, como descoberta e alargamento de si e do mundo. / Mestre em Artes
