Disclosed is a method for providing music information, comprising the steps of: receiving a music signal from a user; generating a continuous melody line corresponding to the music signal, by using pitch frequencies detected from the music signal; converting the continuous melody line into a discrete melody line on the basis of a standard sound length and/or a standard sound pitch; and correcting the discrete melody line by using statistical information on melody progression. La présente invention concerne un procédé permettant de fournir des informations musicales, ledit procédé comprenant les étapes consistant : à recevoir un signal musical d'un utilisateur ; à générer une ligne mélodique continue correspondant au signal musical, en utilisant des fréquences de hauteur tonale détectées à partir du signal musical ; à convertir la ligne mélodique continue en une ligne mélodique discrète sur la base d'une longueur de son standard et/ou d'une hauteur standard ; et à corriger la ligne mélodique discrète en utilisant des informations statistiques concernant la progression de la mélodie. 사용자로부터 음악 신호를 입력 받는 단계; 음악 신호에서 검출되는 피치 주파수들을 이용하여, 음악 신호에 대응하는 연속적인 멜로디 라인을 생성하는 단계; 표준 음 길이 및 표준 음 높이 중 적어도 하나에 기반하여, 연속적인 멜로디 라인을 이산적인 멜로디 라인으로 변환하는 단계; 및 멜로디 진행에 관한 통계 정보를 이용하여, 상기 이산적인 멜로디 라인을 보정하는 단계를 포함하는 음악 정보 제공 방법을 개시한다.
