Keywords: Entrainment. Tarawangsa Art. Ritual Ceremonies. Kesurupan. Biomusic 1 Introduction Tarawangsa is a traditional art form unique to the agrarian community in Rancakalong Village. Sumedang. West Java. Etymologically. Tarawangsa originates from three words: ta, ra, and Ta means movement or motion, ra means great or sun, while wangsa means nation. Thus. Tarawangsa can be interpreted as the epic of the great/sun nationAos life . This traditional art has existed since the era of agrarian societies engaged in farming and was typically performed during the harvest season. It is even mentioned in the Sewaka Darma manuscript, published before the 15th century, indicating that Tarawangsa is an expression of gratitude to the giver of the harvest, namely Dewi Sri or Nyi Pohaci Sanghyang Dangdayang Asri . To this day, this sense of gratitude is directed toward the Almighty . Generally. Tarawangsa is an ensemble consisting of two chordophone instruments: one called tarawangsa, played by bowing, and the other called jentreng, played by plucking . Therefore. Tarawangsa can refer to both a traditional art form in West Java and a bowed musical instrument . The performance of Tarawangsa using only these two musical instruments is unique to Rancakalong. Sumedang. During the performance, there is a male leader known as Saehu, accompanied by seven women called Peribuan. The Tarawangsa art form in Rancakalong consists of three core parts: Ngalungsurkeun, the opening ceremony where the seven Peribuan lower various makeup tools and INCARTURE 2023. December 05-06.

Throughout these three stages, particularly during Nyumpingkeun, the phenomenon of trance or possession is frequently observed. A preliminary assumption is that possession or entering a transcendental state is triggered by exposure to the music played during the Tarawangsa procession. In the field of biomusicology, this phenomenon is referred to as entrainment . 2 Research Methodology This study employs a qualitative approach with a descriptive-analytical method to explore the phenomenon of trance within the Tarawangsa art of Rancakalong. Sumedang. The qualitative approach is chosen for its ability to provide an in-depth understanding of the intricate relationship between traditional music and the altered states of consciousness experienced by participants during The research was conducted in Rancakalong Village. Sumedang Regency, a region renowned for its preservation of the Tarawangsa tradition. The participants in this study include Saehu, the art leader, and Peribuan, the female dancers who play a central role in the performance. Additionally, local community members who observe or participate in the Tarawangsa rituals were engaged to enrich the data collection process. The data were gathered through a combination of techniques designed to capture both the experiential and contextual dimensions of the trance phenomenon. Participant observation was a primary method, allowing the researcher to witness Tarawangsa performances firsthand, particularly during the Nyumpingkeun phase, where trance states were most prevalent. This involved detailed documentation through photographs, videos, and field notes. Furthermore, in-depth interviews were conducted with the Saehu. Peribuan dancers, and local observers to gain insights into their personal experiences of trance, their perceptions of entrainment, and the cultural values embedded in the The study also incorporated an extensive review of historical manuscripts, such as the Sewaka Darma, and scientific literature on biomusicology and entrainment, providing a theoretical foundation and contextual depth. The analysis of data was carried out using a descriptive-interpretive approach. Initially, the data were categorized into themes, such as musical patterns, dance movements, and experiences of A detailed examination of these themes was conducted to identify the phenomenon of entrainment, focusing on how the rhythms of Tarawangsa music influence the biological synchronization of participants' bodies and their progression into altered states of consciousness. Additionally, the study compared the trance observed in Tarawangsa performances with established concepts, such as Dissociative Trance Disorder (DTD), to highlight its unique characteristics. To ensure the validity of the findings, a triangulation of methods was employed. This involved crossreferencing the observations, interview data, and document analysis. Feedback from local practitioners was also sought to verify the authenticity and accuracy of the interpretations. Ethical considerations were strictly adhered to throughout the study. Participants were provided with detailed information about the research objectives and their consent was obtained prior to their Measures were also taken to safeguard the confidentiality of participants and to respect the cultural and traditional values of the community. Through these methodological steps, the research aims to offer a comprehensive understanding of the trance phenomenon in the Tarawangsa art of Rancakalong, highlighting its cultural, musical, and physiological dimensions. 3 Result and Discussion 1 Entrainment Phenomenon Entrainment, or the phenomenon of entrainment, was initially used as a term in meteorology. This condition is characterized by a turbulent flow capturing a non-turbulent flow, as observed in tropical cyclones when moist air captures drier air to follow the same flow and mix . In biomusicology, the term entrainment refers to the process of biological synchronization between the external rhythms of music and dance with an organismAos body . Entrainment is not exclusive to humans. Research, such as that conducted by Patel . , demonstrates that animals, including sea lions and parrots, can also experience this phenomenon. When exposed to external music, humans perceive it auditorily, which activates isochronous pulses within the body. This process causes humans to move in synchrony with external music . According to Patel . , this inductive process is a beat-based rhythmic mechanism, explaining why humans naturally move, sway, or dance when listening to music. In essence, there is a biological synchronization between external music and the body's internal biorhythms. However, entrainment conditions that reach a transcendental state are not solely influenced by While music serves as the initial stimulus, individuals are also affected by collective psychological factors such as fear, belief in supernatural elements, loss of self-identity, and other influences that contribute to an Altered State of Consciousness (ASC). This state arises from cognitive conflicts within one's consciousness, leading to a shift in perception and awareness . 2 Difference between Entrainment and DTD In certain conditions, entrainment is often associated with Dissociative Trance Disorder (DTD) or a condition where someone enters a transcendental phase unconsciously. The possession condition is often linked to DTD, although fundamentally, entrainment conditions and DTD are two very different things. DTD is a type of behavioral disorder involving changes in mental status related to memory and identity. This condition is grouped with DID (Dissociative Identity Disorde. DA (Dissociative Amnesi. DPDRD (Depersonalization/Derealization Disorde. OSDD (Other Specified Dissociative Disorde. , and UDD (Unspecified Dissociative Disorde. As reported by Ginting and Effendy . , it is a type of mental illness caused by various factors, such as hallucinations, illusions, delusions, and so on. However, in one case in Tiga Binanga. North Sumatra, a young woman with no history of mental disorders had to be taken to medical care for DTD, caused by the Nini Pagar traditional culture in the area. In DTD conditions, a sufferer needs psychotherapeutic and pharmacotherapeutic assistance before it adversely affects their life. Entrainment conditions are different from DTD. Entrainment is temporary and gradually disappears when the synchronization between the body's biorhythms and external rhythms ceases. DTD, on the other hand, is a type of illness that requires further treatment, as it endangers the psychological condition of the sufferer. Moreover, entrainment involves other influences such as beliefs, fears, loss of self-confidence, and so on. However, the main stimulus is music. DTD is a psychological disorder condition influenced by other factors, not music. 3 Tarawangsa as an Independent Performing Art The commonality in both cases is the alteration of consciousness due to responses to environmental In the most extreme conditions, both situations result in a loss of the ability to perceive and respond to the surrounding reality normally . In the case of Tarawangsa, participants who dance (Peribua. often enter an extreme entrainment condition. The dancers move randomly following the music of Tarawangsa and Jentreng, adapting to its tempo and beat. The continuously increasing tempo makes the movements of the dancers faster. Based on observations at a Tarawangsa ceremony, extreme entrainment conditions occur most frequently when the tempo is very high. A fundamental difference in Tarawangsa today, at least since the 20s, is that Tarawangsa is more often presented as a performance. Previously. Tarawangsa was part of post-harvest ceremonies, following a series of rituals and being sacred. However, after becoming an independent performing art due to the high demand to witness Tarawangsa as a performing art. Tarawangsa transformed from a ritual art into a secular art. Although losing its dignity as a ritual art. Tarawangsa presented as an independent performing art . part from ceremonie. still induces trance conditions due to entrainment in the dancers, especially Peribuan. The sequence of events remains the same, and the point with the highest occurrence of entrainment peaks is at the highest point of the Tarawangsa music tempo. This proves that the trance occurring in Tarawangsa is not related to rituals, sacredness, or ceremonies. The trance is also not associated with supernatural beings or similar entities often discussed in the context of trance events in Tarawangsa. Based on the theses presented by the author, these trance cases also do not fall under the category of Disociative Trance Disorder (DTD). The condition is temporary and will improve shortly after the Tarawangsa activity is halted. Considering the observable characteristics, it can be concluded that the trance process in Tarawangsa is an entrainment phenomenon. Entrainment phenomena also occur in several traditional arts in Indonesia, such as "kuda lumping," "bambu gila," and various traditional arts involving music and dance. In fact, reported cases related to the emergence of trance phenomena in traditional arts are all linked to music and beat. Music and beat are the two most associated elements with this entrainment process. The body's biorhythms are influenced and attracted by external music that emanates from outside the body. This makes the body's biorhythms and external music become one complete wave. However, in the phenomenon of entrainment, the body's biorhythms will follow the flow or wave of external music. Clayton's research . indicates that beats and tempo are the two most related elements to the occurrence of this entrainment, not the melody or notes of the intended music. 4 Conclusion The phenomenon of trance in the Tarawangsa art of Rancakalong reflects a unique blend of the cultural traditions of agrarian communities, music, and entrainment. Despite the transformation from ritual practices to secular performances. Tarawangsa art continues to evoke trance conditions, vividly illustrating the profound impact of music on human consciousness. Further research is needed to explore the intricate relationship between cultural practices, music, and changes in states of consciousness during Tarawangsa performances. Certainly, this would represent a new advancement for the field of education in the context of Indonesian cultural arts. Reference
