Problems solved by technology

[0004] The technical problem to be solved by the present invention is the defect that the current Chinese national pentatonic mode relies on manual identification. The present invention selects the Chinese national music mode as the research object, and proposes to carry out the Chinese national pentatonic mode by constructing an IACTS (Identification Algorithm of Chinese Traditional Scales) algorithm. Classification, using algorithms to identify the modes of music data samples in the form of MIDI, in order to judge the emotional color of Chinese folk music, which has a certain role in promoting the emotional calculation of Chinese folk music

Embodiment Construction

[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] refer to figure 1 , which is a flowchart of an embodiment of the Chinese national pentatonic emotion recognition method of the present invention. The Chinese national pentatonic emotion recognition method of this implementation comprises the following steps:

[0039] S1. Obtain and decode the MIDI file of a piece of music, and extract all the data representing the pitch therefrom;

[0040] S2. Process the data, remove repeated pitches, and sort the remaining pitches according to the audio size of the pitches to obtain a pitch sequence;

[0041] S3, find out all intervals that can form a major third or lower several octaves to form a new pitch sequence from the pitch sequence;

[0042] S4. Remove the preset pit...

Abstract

The invention discloses a Chinese national pentatonic emotion recognition method and a Chinese national pentatonic emotion recognition system. Firstly, by decoding a MIDI file, all data representing pitches are extracted, repetitive sounds are removed, and pitch sequences are obtained by sorting pitches. The IACTS algorithm is used to identify the data and verify the results, so as to accurately judge the modal of the data. After finding out the Gongyin, all the notes in the music will be classified according to the Gongyin-based pitch relationship. If all the notes can be accurately classified according to the pitch relationship with the Gongyin, then the check is passed and the mode is finally determined. Conversely, if there is a special interval outside the mode, the verification willnot pass; at last, the emotion color of Chinese folk music is judged according to the generally accepted classification method: fu color and feather color.

Description

technical field [0001] The present invention relates to the field of emotion recognition, and more specifically, relates to a Chinese national pentatonic emotion recognition method and system. Background technique [0002] One of the most important issues in the current field of artificial intelligence is the calculation and processing of human emotions. On the one hand, emotional computing is a requirement for improving the human-computer interaction experience, and on the other hand, it is also a requirement for realizing artificial intelligence in the true sense. Therefore, the calculation and application of human emotions is particularly important. The expression of human emotions requires a certain carrier, and music is an important art form that carries human emotions. The human emotions carried by music are extremely complex, but the constituent elements of music can be quantified. By quantitatively analyzing the various constituent elements of music and mapping the...
