1. Introduction

Music, as an art form that transcends eras and cultures, carries profound historical and cultural value. Musical cultural heritage embodies the significant manifestation of human history and cultural diversity. It represents not merely an exhibition of art but also a crucial component of social and cultural identity. Musical cultural heritage encompasses, but is not limited to, traditional music, folk songs, ceremonial music, and related cultural expressions. As witnesses to history, these heritages record the evolution of human civilization and serve as vital channels for the transmission of cultural and societal values [1]. However, the preservation of musical cultural heritage faces numerous challenges. With the acceleration of globalization in politics, economy, culture, and changes in modern lifestyles, many traditional forms of music and expressions are gradually disappearing [2]. For instance, specific ethnic instruments and performing arts face the threat of extinction due to a lack of successors or audience. Additionally, the ongoing development of science and technology poses challenges to the preservation of musical cultural heritage, as the authenticity of music forms and traditional performance methods are impacted by modern media [3].

In this context, the protection and transmission of musical cultural heritage become increasingly critical. Due to its multifaceted information and diverse presentation methods, existing preservation approaches—such as manual recording, documentary collection, digital capture, and information documentation—often face limitations due to resources and technology, affecting their effectiveness. Therefore, in the digital age, finding effective ways to protect and transmit this heritage to ensure its comprehensive, in-depth understanding and appreciation by a broader audience is an urgent issue to address [4].

Digital twin technology, as an emerging digitalization technique and exhibition concept, offers a new perspective and potential for the preservation of musical cultural heritage. By creating a virtual world as a novel platform for cultural dissemination, it presents musical cultural heritage in digital form to the public. The construction of digital twins for musical cultural heritage not only allows for more comprehensive recording and preservation of musical works, instruments, and methods of performance but also provides researchers and the public with an interactive and immersive experience. This approach not only enhances public awareness and interest in musical cultural heritage, allowing for interaction and experience in digital spaces but also offers new perspectives and tools for its preservation [5]. This has significant implications for the protection and dissemination of musical cultural heritage.

This paper proposes a new method for preserving and transmitting musical cultural heritage in virtual museums using digital twin technology. It focuses on exploring and evaluating the application of digital twin technology in the protection of musical cultural heritage within virtual museums. The paper will delve into how digital twin technology can replicate and reproduce musical cultural heritage in virtual museums, including specific applications, challenges faced, and potential solutions. To demonstrate the effectiveness of this method, the paper uses Kunqu Opera from China as a case study to construct a virtual music community and interactive platform. Through an analysis of user experience and transmission effects, this method not only effectively preserves musical cultural heritage but also provides the public with a new, highly interactive way to deepen their understanding and appreciation of musical cultural heritage, thereby promoting its protection and sustainable transmission.

2.1. Analysis on the Current Situation of Music Cultural Heritage Protection

Musical cultural heritage, broadly defined, encompasses all cultural and historical information conveyed through music. This includes not only various musical compositions, such as traditional songs, ethnic music, and religious music, but also related practices of performance, musical instruments, music production techniques, and the role of music in social and cultural activities. As a form of cultural expression, music is an integral part of human history and social structure, reflecting the diversity, creativity, and understanding of the world across human societies [6].

The importance of musical cultural heritage lies in its unique cultural and educational value. Firstly, music serves as a powerful medium for conveying and preserving history, culture, and traditions. Through music, individuals can learn about and experience the historical narratives, lifestyles, and values of different cultural backgrounds [7]. Moreover, musical cultural heritage is a significant marker of ethnic and regional cultural identities, fostering connections between individuals and communities and promoting an understanding and respect for cultural diversity [8]. However, many traditional musical forms have been neglected or forgotten, especially those transmitted orally. Thus, the protection of musical cultural heritage is not only about preserving the past but also about maintaining cultural diversity and promoting the sustainable development of future cultures [9].

The preservation of musical cultural heritage currently faces multifaceted challenges and limitations, stemming from changes in the external environment as well as the inherent limitations of preservation methods. In the process of globalization and modernization, traditional musical cultural heritage is at risk of marginalization and neglect. The rise of mainstream culture and commercial entertainment forms in modern society makes it difficult for traditional music to compete, reducing opportunities for its dissemination and performance and impacting the younger generation’s interest and transmission of traditional music [10]. The rapid development of technology has, to some extent, altered the ways in which music is produced and disseminated. Although modern technology has facilitated the recording and preservation of music, it may also affect the authenticity of musical expression. For example, music recorded through digital means might not fully capture the nuances and emotional expressions of live performances [11]. Many traditional musical forms rely on oral transmission, which, despite its personalization and flexibility, is extremely vulnerable. Once the number of transmitters decreases or breaks, the related musical cultural heritage may be lost permanently [12]. The protection and transmission of musical cultural heritage require corresponding resources and financial support, including training transmitters, organizing musical events, and recording and preserving music. However, in many cases, these activities have not received sufficient attention and financial support, especially in economically disadvantaged regions [13]. Currently, methods used for the preservation of musical cultural heritage are often limited to the physical recording of music and the collection of documentary materials. Although these methods have played a role in preserving musical compositions, they are insufficient in transmitting the skills and expressive methods of musical performance [14]. Given these challenges and limitations, exploring new preservation methods and technological applications for the protection of musical cultural heritage is particularly important and urgent.

2.2. Application Analysis of Digital Twin Technology

Over time, with technological advancements, the diversity and flexibility of digital twin technology have led to its broad application across different fields. Particularly under the influence of Industry 4.0 and the Internet of Things (IoT), digital twins have become a key technology in manufacturing, urban planning, healthcare, and more [16]. In the manufacturing sector, digital twins are utilized to create virtual copies of products to optimize design, test performance, and predict maintenance needs [17]. In urban planning, the application of digital twins aids city administrators in more effectively monitoring and managing urban infrastructure [18]. In the medical field, digital twin technology is employed to simulate human organs or entire physiological systems, optimizing treatment plans and pre-operative procedures [19]. The energy industry uses digital twins to monitor and optimize the production and distribution of energy [20]. In recent years, with improvements in computing power and advancements in data analysis techniques, digital twin technology has become more efficient and precise in simulating complex systems and processes.

In the field of cultural heritage preservation, digital twin technology offers a novel perspective. By constructing accurate digital models of historical buildings, artworks, or even entire historical scenes, it not only provides rich resources for research and education but also scientific foundations and methods for the preservation and restoration of cultural heritage. Notably, digital twin technology can capture and reproduce the intricate features and historical contexts of cultural heritage, which is particularly important for protecting heritage that is vulnerable to environmental and temporal degradation. Furthermore, the application of digital twins in cultural heritage preservation extends beyond the replication and archiving of physical characteristics. By integrating virtual reality (VR), augmented reality (AR), and other interactive technologies, digital twins can offer the public immersive cultural experiences, allowing people to transcend the boundaries of time and space to directly experience and learn about different cultures. In this process, public participation and experience become active parts of cultural transmission, which is significant for enhancing societal recognition and awareness of the value of cultural heritage. Therefore, this paper aims to explore the potential and application of digital twin technology in the preservation of musical cultural heritage, particularly in the context of virtual museums. Through this research, we seek to reveal how digital twin technology can help us better understand, preserve, and transmit precious musical cultural heritage.
