| Abstract(in English) | This paper proposes a method for the accurate estimation of major chords and minor chords in musical audio signals, using the rules of musical chords. Chords are important for analysing the compositon of musical audio signals, and need to be estimated accurately. Then, studies of the estimation of chords have been done, based on the estimation of single tones. However, it is difficult to estimate chords accurately when many single tones exist at a time. Then, first, the proposed method estimates the pitches of the bass sounds which form the basis of chords. Secondly the method calculates the energy of the frequency which corresponds to the major and the minor intervals, and compares them. Consequently, the proposed method can estimate chords without complete estimation of the single tones which are included in chords. |
