This study aims to propose a comparison model of Chinese and Japanese traditional opera tunes based on deep learning (DL) and artificial intelligence technology, which can be used to effectively analyze and classify the tune characteristics of Chinese and Japanese traditional opera. To achieve this aim, a multi-layered DL model, including Convolutional Neural Network, Long Short-Term Memory, Recurrent Neural Network, and Gated Recurrent Unit, is constructed based on the tune characteristics of Chinese and Japanese traditional opera. In the extensive experimental verification, the proposed model has achieved remarkable results in the task of classifying Chinese and Japanese traditional opera tunes. Specifically, the proposed model achieves an accuracy of 89% and 88%, recall of 88% and 87%, and F1-score of 88% and 87% in the tune classification task of the Chinese and Japanese traditional opera, respectively. Compared with similar models, the proposed model performs better in classification.

A. RESEARCH BACKGROUND AND MOTIVATIONSWith the development of globalization and the swift growth of science and technology, as an important cultural heritage of China and Japan, traditional opera's protection, inheritance, and innovation have attracted more and more attention [1][2][3]. However, due to the differences between China and Japan in language, culture, history, and other aspects, the inheritance and development of Chinese and Japanese traditional operas face many challenges [4][5]. Among them, how to dig deeply and compare the tune characteristics of Chinese and Japanese traditional operas has become a topic worthy of study [6][7][8]. The tune is a vital part of traditional opera, which not only represents the opera's musical style and singing characteristics but also contains rich cultural connotations and artistic values [9-10]. The comparative analysis of Chinese and Japanese traditional opera tunes allows the similarities and differences between their traditional opera art to be better understood, thus providing references for the cross-cultural communication and inheritance of the two countries' traditional opera [11][12][13]. However, the comparative studies on Chinese and Japanese traditional opera tunes are relatively few and lack systematism and depth [14].Furthermore, China and Japan have deep historical and cultural origins, and there are many similarities in the traditional opera art between the two countries [15][16][17]. However, due to differences in language, region, and other aspects, there are also obvious differences between Chinese and Japanese traditional operas regarding tunes, performance, and costumes [18]. This difference is reflected in the form of performance on the surface, cultural connotation, and artistic value [19][20][21]. A comparative study of Chinese and Japanese traditional opera tunes can help to better understand the d...
