Resumo: The text discusses the application of feature-data retrieved and processed by audio descriptors and multivariate statistical methods – particularly, by employing principal component analysis (PCA). Adopting Trevor Wishart’s Imago (2002) as a case study, we present an analytical strategy that seeks to correlate the quantitative data and techniques of descriptors and multivariate statistics with qualitative approaches based on listening (solfège, in Schaefferian terms). Finally, we seek to demonstrate the potential assets of localized, precise, dialectical and contextual explorations of these specific techniques to support computer-assisted analytical researches that require the coordination of listening-based and data-informed investigative approaches.

Adotando Imago (2002) de Trevor Wishart como estudo de caso, apresentamos uma estratégia analítica que busca correlacionar dados quantitativos e técnicas de descritores e estatísticas multivariadas com abordagens qualitativas baseadas na escuta (solfège, em termos schaefferianos). Por fim, procuramos demonstrar os ativos potenciais de explorações localizadas, precisas, dialéticas e contextuais dessas técnicas específicas para apoiar pesquisas analíticas assistidas por computador que requerem a coordenação de abordagens investigativas baseadas em escuta e informadas por dados.engUniversidade Federal de Minas GeraisUFMGBrasilCAC - COORDENADORIA DE ASSUNTOS COMUNITARIOSMUS - DEPARTAMENTO DE TEORIA GERAL DA MÚSICAInternacional Meeting on Music Theory and AnalysisAnálise de componentes principaisMúsica por computadorSistemas de informação musicalMúsica - EstatísticaPrincipal component analysisImagoTrevor WishartElectroacoustic musicMusic information retrievalAnalysis informed by audio features associated with statistical methods : a case study on 'Imago' (2002) by Trevor WishartAnálise informada por recursos de áudio associados a métodos estatísticos: um estudo de caso sobre 'Imago' (2002) de Trevor Wishartinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjecthttps://eitam5.nics.unicamp.br/en/proceedings/Fellipe Miranda MartinsJosé Henrique Padovani Vellosoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
