「Strummer」 を提案する．Strummer システムの開発にあたり，コードラベルが付与された 727 曲分の楽曲データを解析し，コードの出現率と難易度を考慮した曲の重要性の尺度を新たに定義した．これをシステム中で用いることで，ユーザは簡単かつ重要な楽曲から練習が可能になる．さらに，本システムは音響信号解析によってユーザが正しいコードを弾いたのかを認識してフィードバックする機能を有しており，インタラクティブかつ段階的な練習を提供する．実験では 5 人のギター初心者に計 5 時間ずつ本システムを用いてギター練習をしてもらい，インタビューやアンケートを実施し，本システムの評価を行った．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告音楽情報科学（MUS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-02-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"24","bibliographicVolumeNumber":"2017-MUS-114"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
