摘要： The present invention concerns a music audio representation method for analyzing a music audio signal (2) in order to extract a set of Chord Family Profiles (CFP) contained in the audio music signal (2), the method comprising the steps of: a) applying a first algorithm (4) to the music audio signal (2) in order to extract first data (5) representative of the tonality of music audio signal (2), and b) applying a second algorithm (6) to said first data (5) in order to provide second data (7) representative of the tonal centre contained in the first data (5).
