For that purpose, musical features which can be extracted from audio performed by musicians are proposed by interpreting various qualitative features stated in Style Analysis by LaRue et al., one of musicological analysis methods. Composer discrimination accuracy evaluated with canonical discriminant analysis showed points of music by the same composer in the feature space of proposed features are placed nearby. In addition, specified coordinate of composers' centroids in the space are shown to correlate to their generations, and points of composers having similar geographical backgrounds are also shown to be allocated nearby in the space with the other coordinates. Therefore, the proposed musical features are presumed to be valid for estimating composer-characteristic impression and the chronological and geographical impression.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2558","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2546","bibliographicIssueDates":{"bibliographicIssueDate":"2014-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"55"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:50:40.674297+00:00","id":107502,"links":{}}
