Abstract

Information processing apparatus, musical composition section extracting method, and program is provided. The information processing apparatus includes: a musical composition section extracting unit which extracts musical composition sections with tempos which are close to a preset reference tempo based on tempo information indicating a tempo of each section constituting musical compositions; a harmonization level calculating unit which calculates a harmonization degree for a pair of musical composition sections extracted by the musical composition section extracting unit, based on chord progression information indicating chord progression of each section constituting musical compositions; and a harmonization section extracting unit which extracts a pair of sections with a high harmonization degree for the musical compositions calculated by the harmonization level calculating unit from among sections extracted by the musical composition section extracting unit, wherein the harmonization level calculating unit weights the harmonization degree for the musical compositions such that a large value is set to the harmonization degree between musical compositions with a predetermined relationship.

Description

technical field [0001] The invention relates to an information processing device, a method and a program for extracting pieces of music. Background technique [0002] There is a method of extracting desirable partial pieces of music from a plurality of pieces of music prepared in advance, and then connecting the extracted pieces of music to each other. This method is called remixing. In a scene such as a club event, multiple musical pieces are reproducibly prepared, and remixing is realized by manually controlling the reproduction timing and volume of each musical piece. In addition, at present, more and more people enjoy the fun of remixing. For example, more people remix music to match the rhythm of jogging to generate original music to listen to while jogging. [0003] However, seamlessly connecting pieces without reducing the musicality and rhythmicity of the joints between pieces requires skill. Therefore, it is difficult for many users who are not skilled in the te...
