ABSTRACT
With a high sound quality stimulated by the electrical device and a large inclusion in medical insurance, the number of cochlear implant recipients has been rapidly increased in Korea. Today, it is not surprising that early implanted young children with congenital deafness show a similar performance to their normal hearing peers in speech perception. However, the cochlear implant users still have a trouble to enjoy music. This review study aims to introduce briefly about acoustic components that required to perceive the music and understand a relationship between cochlear implantation and temporal fine structure. For the pediatric implant users who have less experience on acoustical sound features but are much familiar with the electrically stimulated sound, perceiving the music seems to be challengeable due to the lack of temporal fine resolution related to pitch and timbre among various components of music. Four representative test batteries for evaluating the recipients' ability of the music perception were mentioned and effective auditory music trainings were discussed with analysis of related investigations. Unlike hearing aids users who usually depend on fitting algorism for better music quality, the cochlear implant users need systematic training to improve their music perception ability. In conclusion, advancement of speech processing technology which can provide accurate information about the temporal fine structure of incoming music to the recipients needs to be developed. Also, a practical application of music training should be recommended as a part of auditory training for the cochlear implant users.

O Ouvido Absoluto, a capacidade de nomear tons sem uma referência externa, é comumente relacionada à cognição musical. Embora se note um crescente investimento em seu estudo, muitas questões ainda encontram-se pouco esclarecidas, tais quais: gênese, conceito, metodologias de estudo, aspectos estruturais e funcionais que o caracterizam. Esta revisão propõe-se a analisar os avanços recentes e limitações da área, considerando-se as bases metodológicas e teóricas, bem como pontos controversos que permeiam o tema, como a definição e origem da habilidade. Como conclusão, aponta-se a necessidade de delineamentos específicos para o estudo da cognição musical como um aliado importante para a melhor compreensão e elucidação dos problemas inerentes ao Ouvido Absoluto...
Absolute pitch, the ability to name tones without an external reference, is commonly related to music cognition. Despite the growing investment in its understanding, many questions are still poorly understood, such as genesis, conceptualization, research methodology, identification of structural and functional features. The present review aims to analyze recent advances and limitations in the area, considering its methodological and theoretical bases, as well as existing controversies (definition and genesis). It concludes by pointing the need for specific designs for the study of musical cognition for a better understanding of absolute pitch...

In the past few years the study of music from a neuroscientific perspective has considerably improved, allowing the evolution of both theoretical knowledge and constructs related to cognitive musical processing. Both neuroimaging studies and studies of individuals who suffer from selective deficits of musical abilities have favored the construction of useful models to understand the mechanisms of musical processing, thus revealing its complexity and eliciting the hypothesis of the modular organization of music in the brain. This article reviews studies of cognitive musical processing with a focus on deficits in musical abilities and the neuropsychological model of cognitive musical processing developed by Isabelle Peretz. This model is an important contribution to neuroscientific studies of music because it furthers the understanding of selective deficits in different components of musical processing that occur in both individuals who incur brain damage and those with congenital amusia. The model also serves as theoretical support for diagnosing different types of amusia.

OBJECTIVES: Although the cochlear implant (CI) is successful for understanding speech in patients with severe to profound hearing loss, listening to music is a challenging task to most CI listeners. The purpose of this study was to assess music perception ability and to provide clinically useful information regarding CI rehabilitation. METHODS: Ten normal hearing and ten CI listeners with implant experience, ranging 2 to 6 years, participated in the subtests of pitch, rhythm, melody, and instrument. A synthesized piano tone was used as musical stimuli. Participants were asked to discriminate two different tones during the pitch subtest. The rhythm subtest was constructed with sets of five, six, and seven intervals. The melody & instrument subtests assessed recognition of eight familiar melodies and five musical instruments from a closed set, respectively. RESULTS: CI listeners performed significantly poorer than normal hearing listeners in pitch, melody, and instrument identification tasks. No significant differences were observed in rhythm recognition between groups. Correlations were not found between music perception ability and word recognition scores. CONCLUSION: The results are consistent with previous studies that have shown that pitch, melody, and instrument identifications are difficult to identify for CI users. Our results can provide fundamental information concerning the development of CI rehabilitation tools.

Este estudo objetivou realizar a adaptação cultural da Montreal Battery of Evaluation of Amusia - MBEA, que se constitui em uma bateria de testes que avalia funções musicais, visando sua adaptação para a população de adolescentes brasileiros. Foram realizadas três etapas: equivalência conceitual, equivalência de itens e equivalência semântica. Participaram deste estudo 20 juízes não-especialistas e 6 juízes especialistas, responsáveis por avaliar os itens da MBEA e seus construtos. Na análise de conteúdo, obtiveram-se altos índices de concordância entre os juízes, exceto para os construtos escala e intervalo. Pelos grupos focais, observou-se que os adolescentes associaram os itens à música erudita, mas isto não afetou sua compreensão do teste. Quanto à equivalência cultural, 70 por cento dos itens apresentaram altos índices de concordância entre juízes. Na equivalência semântica não se apresentaram diferenças significativas entre as retraduções e a versão original. Concluiu-se ser adequado manter os itens originais do teste, pois, além de compreensíveis para a população-alvo, são compostos dentro do sistema tonal ocidental, o qual é utilizado em ambas as culturas.
This study aimed to perform a cultural adaptation of the Montreal Battery of Evaluation of Amusia - MBEA, which constitutes a battery of tests that evaluates musical functions, in order to adapt them to the population of Brazilian adolescents. Research was conducted in three stages: conceptual equivalence, items equivalence and semantic equivalence. The study included 20 non-expert judges and 6 expert judges, responsible for assessing the items of MBEA and their constructs. In the analysis of content, there were high rates of agreement among the judges, except for the constructs of scale and intervals. Considering focus groups, it was observed that adolescents associated the items with classical music, but this did not affect their understanding of the test. Concerning cultural equivalence, 70 percent of the items had high rates of agreement among judges. Regarding semantic equivalence, there were no significant differences between the back translation and the original version. We conclude to be appropriate to maintain the original items of the test because, in addition to being comprehensible to the target population, they are made within the Western tonal system, which is used in both cultures.
