Abstract

La présente invention se rapporte au domaine technique du traitement de données, et concerne, en particulier, un procédé de génération de chanson, un appareil, un dispositif électronique et un support de stockage. Le procédé de génération de chanson consiste à : recevoir une première instruction de confirmation, et sur la base de la première instruction de confirmation, acquérir des premières informations d'attribut musical et une étiquette d'humeur pour une chanson ; sur la base d'une relation d'association prédéfinie entre des étiquettes d'humeur et des propriétés musicales et sur la base de l'étiquette d'humeur, déterminer des secondes informations d'attribut musical pour la chanson ; amener les premières informations d'attribut musical et les secondes informations d'attribut musical à servir de conditions de filtrage pour traverser une base de données de musiques pré-construite, pour acquérir des segments musicaux candidats correspondant aux conditions de filtrage ; et sur la base d'une seconde instruction de confirmation reçue, sélectionner des segments musicaux parmi les segments musicaux candidats, et assembler les segments musicaux selon une séquence correspondante de mesures de musique pour acquérir une nouvelle chanson. Grâce au procédé proposé dans la présente invention, de nouvelles chansons répondant aux exigences d'un utilisateur peuvent être générées de manière contrôlable.
