Autopercepção vocal de coristas profissionais

Abstract

OBJETIVO: identificar o nível de autopercepção vocal de cantores de um coral profissional. MÉTODO: participaram 44 coristas, com idades entre 20 e 75 anos (<img border=0 width=16 height=20 src="../img/x.jpg" align=absmiddle> 51,5 ± 14,36), de ambos os sexos. Estes responderam a um questionário com 30 questões objetivas sobre autopercepção vocal e queixas da voz cantada e falada; experiência com o canto e hábitos relacionados ao bem estar vocal. RESULTADOS: todos os coristas auto definiram suas vozes com características positivas, não apresentando diferença estatística entre voz falada e cantada. Os coristas identificaram também características vocais negativas para voz falada e cantada, sendo que foi encontrada diferença estatística. O índice de queixas vocais foi de 31% para voz falada e 25% para voz cantada, sem apresentar diferença estatística. 43% dos participantes realizaram aulas de canto, com tempo médio 1,95 anos (± 2,29 anos) e o tempo de participação em corais variou de seis meses a 66 anos, com tempo médio de 17,74 anos (± 18,45 anos). Quanto aos hábitos relacionados ao bem estar vocal, o índice médio de ingestão diária de água foi de 1,7 litros (± 0,92 litros); 50% dos coristas fazem ingestão de álcool com frequência; o índice numérico de tabagistas foi de 4,5% e 22% dos coristas são ex-tabagistas. Não foram encontradas correlações estatísticas entre tabagismo, etilismo e experiência no canto com queixas vocais. CONCLUSÃO: os coristas avaliados apresentaram um nível elevado de autopercepção de seus aspectos vocais, podendo sugerir que o canto coral desempenha um papel importante na promoção do bem estar vocal.

Características da voz falada de idosas com prática de canto coral

“…The aspects of the voice of the elderly in the NSG are in compliance with the literature, which describes a worsening of the vocal quality with aging (1,3) . These findings corroborate research which indicates that choral singing can help promoting vocal health and preventing vocal aging (15,16,18,19,(21)(22)(23)(24) . Specifically for vocal strain, statistical analysis of the terciles shows that the results presented two directions ( Table 4).…”

“…It is worth mentioning that the rate of complaints regarding singing (16%) can be attributed to the auditory refinement acquired with choral singing, a fact that improves the self-perception of singers about their own voices (12)(13)(14) . Results also show that, owing to the practice of singing, the subjects in the SG were more careful and abused less of their voices compared with the subjects in the NSG (2,16,(22)(23)(24) . Such a fact can be observed in the variable water consumption, which was significantly greater in the higher categories of consumption in the SG compared with the NSG (Table 1).…”

“…It is noteworthy that this perception of deep/low voice by the women in the SG occurs due to the improved self-perception developed with the choral singing experience, as well as because they have a more intense and refined vocal demand (17,18,24) . As for the auditory-perceptual analysis of the speaking voice, significant differences were found between the groups regarding the overall degree of deviance and the presence of roughness and strain, with occurrence of greater values for the NSG (Table 3).…”

“…For example, the intense vocal demand of choral singing encourages increased water consumption, which is considered a health promotion measure because it prevents the wear of laryngeal structures. Most of the times, choral singing helps individuals become more careful with their vocal health; it is, therefore, a preventive action because it allows access to information (2,(22)(23)(24) . It is worth noting that choral singing promotes increased respiratory support to practicing individuals, balances resonance and loudness modulation, in addition to increasing vocal range, which is considered excellent for the elderly, considering that monotone voice (which uses fewer musical notes) is one of the aspects of presbyphonia (24)(25)(26) .…”

However, there are differences between speaking voice and singing voice that should be considered: in singing, breathing is programmed according to the musical phrases; greater vocal range is used; loudness is stronger and less constant than in speaking; resonance is high with greater participation of the vocal tract; and voice quality is more stable and richer in harmonics (25) .…”
