Abstract

The invention discloses a music melody rhythm analysis and extraction method and device, and relates to the technical field of computers. The method includes: preprocessing the MIDI music file to obtain a target audio track; traversing all the notes in the target audio track to obtain the start time value and end time value of each note; identifying the root of the chord tone in the target audio track ;Process the polyphony in the target track into multiple single tones; splicing the root, multiple single tones and other notes according to the start time and end time of the note to obtain a complete melody rhythm, and identify the melody rhythm Each phrase of each phrase and the phrases in each phrase; the similarity analysis is performed on all the phrases, and the time value similarity of each phrase is obtained and the corresponding labels are marked. The method and device for analyzing and extracting music melody rhythm disclosed by the invention can realize the extraction and analysis of music rhythm, better excavate hidden information in rhythm structure, and better guide the research and development of computer music creation.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a music melody rhythm analysis and extraction method and device. Background technique [0002] With the development and progress of science and technology, the use of computers to create music has gradually begun to be applied. Using computers to create music can greatly reduce the workload of human music creation, and it is expected to produce novel music that breaks the shackles of traditional thinking. It cannot be compared with human musicians, but machine works can provide human beings with candidate or primary works, making it easier for composers to create, so using computers to create music has a very broad application scenario. [0003] In the process of computer music creation and analysis, the extraction and analysis of music melody and rhythm is an indispensable process. At present, the existing technology is to extract the rhythmic time-value structure manually or...
