Abstract

The invention belongs to the technical field of mode identification, and particularly relates to a method and a system for identifying a mode of five-tone music. The method comprises the following steps: acquiring a music audio to be identified; extracting chromaticity features of the music audio to be identified; constructing and training a mode recognition model; and inputting the chromaticity characteristics of the music audio to be identified into a trained mode identification model to obtain the mode of the music audio to be identified, the system correspondingly comprises four modules, according to the invention, the mode identification is directly carried out on the music audio, and the identification precision and the identification reliability can be improved.

Description

technical field [0001] The invention belongs to the technical field of mode identification, and in particular relates to a method and system for mode identification of pentatonic music. Background technique [0002] Mode is the form of musical tone organization, which means that several musical tones with different heights surround a stable central tone and are organized together according to a certain interval relationship to form an organic system. The central tone of the mode is used as the starting tone and the ending tone, and the other tones are arranged in the order of pitch in the form of a scale, which is called a mode scale. [0003] Foreign research on mode identification mainly focuses on the identification of key signatures and major and minor modes. Because there are certain differences between Chinese pentatonic musical modes and foreign modes, and there is a lack of a complete and standard database with key annotations, the current research on Chinese pentato...
