Previous systems extracted just one parameter as solist's intention and output accompaniment switching registered patterns according to the parameter. Our system can understand solist's intention in more detail by extracting five parameters as his intention from various aspect of solo. In addition, to make accompaniment rich in variation, this system directly alters accompaniment data such as loudness, pitch and the number of notes, according to those parameters. In our experiment, it output appropriate accompaniment following the solist's intention of solo.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"12","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告音楽情報科学(MUS)"}],"bibliographicPageStart":"7","bibliographicIssueDates":{"bibliographicIssueDate":"1995-02-24","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19(1994-MUS-009)","bibliographicVolumeNumber":"1995"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":56512,"links":{}}
