Embodiment Construction

[0031] This implementation example will further describe the specific implementation of the present invention in conjunction with the accompanying drawings, but the implementation of the present invention is not limited thereto. technology achieved.

[0032] figure 1 for the entire workflow of the classification method. The specific process is as follows:

[0033] Step 1: The MIDI data set passes through the sample acquisition unit to generate multiple samples;

[0034] Step 2: If training is required, skip to step 3, and if classification is required, skip to step 5;

[0035] Step 3: Adjust the data classification module to training mode;

[0036] Step 4: Input all samples generated in step 1 to the data classification unit for multiple rounds of training until the deep neural network of the data classification module achieves a good classification effect, and the whole process ends;

[0037] Step 5: Adjust the data classification module to the classification mode;

[003...

Abstract

The invention discloses a musical instrument digital interface (MIDI) piano music style classification method integrated with accompaniment. The MIDI piano music style classification method is implemented by using a sample collection unit and a data classification unit. According to the sample collection unit, music section samples containing main melody and accompaniment information are extractedfrom a piano piece, each music section sample consists of a fixed number of note vectors, each note vector contains pitch of main melody notes, the starting time of the main melody notes in the corresponding section, the time of duration of the main melody notes and the possible pitch information of accompaniment notes of the main melody notes; and the data classification unit is used for receiving samples of the sample collection unit for training and classification. In the classification process, the influence of accompaniment on music style is considered, the number of samples is increasedby the sample collection unit, and therefore the accuracy of classification is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a MIDI piano music style classification method with fusion accompaniment. Background technique [0002] The piano originated in the early 18th century and is a keyboard instrument of Western classical music. It consists of 88 keys and a metal string soundboard. Under the promotion of Mozart, Brahms, Liszt and other outstanding musicians, it gradually became known as the king of musical instruments. Today, it provides conditions for the creation of musicians, and the piano culture developed by musicians has promoted the further maturity of the structure and function of the piano. [0003] Piano music refers to music played on the piano, sometimes accompanied by other musical instruments. With the advent of the Internet age, multimedia applications are becoming more and more extensive, and piano music has entered our lives. From the creative process of music creators to ...
