Muhammad Rayhan Sudrajat (b. 1990) is an academician, ethnomusicologist, educator, vocal coach, composer, and content creator whose work explores the intersection of traditional music, digital technologies, and cross-cultural collaboration. He is a Sound Arts, Arts & Ethnography, and Public Speaking lecturer at Universitas Katolik Parahyangan (UNPAR), Bandung, where he engages students in the evolving dialogue between sound, culture, and technology.

Upon completing his Master's degree in Ethnomusicology & Musicology at Monash University in 2020, Rayhan is an active musician, blending traditional Indonesian music with contemporary and electronic elements. He has collaborated with artists from America, Africa, Europe, Asia, and Australia, advocating for a new sonic language that bridges tradition and modernity. His passion for vocal artistry has led him to coach musicians and performers through engagements with Shure Incorporated, Sony, Yamaha, and Universitas Gadjah Mada, among others.

Rayhan has been a featured speaker at Goethe-Institut, Institut Français, and TEDxUNPAR, presenting on topics such as modular synthesis, digital ethnography, and the evolution of Indonesian music in contemporary soundscapes. His written works include academic book chapters, research papers, and artist statements that explore themes of sound, identity, and innovation.

Rayhan’s expertise is deeply rooted in his fieldwork in Central Kalimantan, where he has worked extensively with Dayak communities through education and cultural initiatives. His collaboration with local NGOs and schools has focused on cultural preservation and sustainable artistic development, leading him to spearhead Festival Kampung Buntoi—the first festival in the region dedicated to fostering creative exchange between rural communities and urban artists from across Indonesia. This commitment to cultural engagement also led to his selection as the sole Indonesian fellow for OneBeat in 2017, a prestigious U.S. Department of State program that unites musicians from the Asia-Pacific in cross-cultural artistic dialogue.

As an advocate for cultural sustainability, Rayhan believes traditional music is a historical archive and a living, evolving art form. His work continues to challenge boundaries, bringing Indonesia’s diverse musical heritage to broader, younger, and increasingly global audiences.
