This book intends to explain the development of the knowledge of Mek Mulung, a dance drama that is based in Wang Tepus, Jitra Kedah using archival evidence and ethnographic research. Since its earliest known documentation through in the writings of Walter William Skeat published in 1900, very little of Mek Mulung was described comprehensively. This book describes Mek Mulung in five chapters. It begins with its overview, describing the beholders of the tradition, the performance style, new creative ideas and heritage revival activities integrated towards the idea of the performance. Readers of the book can also experience the music of Mek Mulung by listening to musical examples as well as interacting with the dance and movements through an augmented reality mobile phone application which accompanies the book. The integrated multi-sensory experience of this book aims to enrich and help readers to appreciate Mek Mulung as a heritage performance.
