 note = {本稿では，音楽的知識であるdoubly nested Circle of Fifthsに基づいた楽曲の和音情報を抽出する方法を提案する．この情報は，和音の類似性を表す特徴ベクトルを写像することにより生成され，DNCOFベクトルと呼ばれる．本研究はDNCOFベクトルの時系列にHMMを用いて和音とその境界の検出を試みる．, In this paper, we propose a novel method to obtain music chord information based on the musical theory known as “doubly nested Circle of Fifths”. We can obtain information by mapping features and call them “DNCOF vectors”. In this study, we apply HMM to the traces of DNCOF vectors to track music chords and detect their boundaries.},
