This paper presents an efficient method for chord transcription of music signals. A succession of chroma vectors is calculated from the signal in order to extract the musical content of the piece over time. We introduce a set of chord templates for several types of chords (major, minor, dominant seventh, ...): different chord models taking into account one or more harmonics of the notes of the chord are considered. In order to fit the chroma vectors to the chord templates, we analytically… CONTINUE READING
