Local arts groups generally possess a wealth of practices rooted in tradition and the environment,but face limitations in developing contemporary artistic approaches. This community service program aims to support Sanggar Gadhoeng Mlati in Ngampel Village, Dukun Subdistrict, Magelang Regency in developing capacity for integrative art based on soundscapes through a practice-based research (PBR) and participatory approach over a five-month period. The program was carried out in four phases: field observation and participatory acoustic mapping; outreach and collaborative design; a one-day integrative workshop with three facilitators covering sound sensitivity, kinesthetic response, and nature-based vocal creativity; and an integrative arts performance combined with soundscape recording along the riverbank. Following the workshop, measurements were taken using a pretest-posttest instrument on 30 participants across six competency indicators (scale 1–4) using Hake’s (1998) Normalized Gain (N-Gain) formula. The results showed that all indicators fell into the “High” category with an overall N-Gain of 82.41% (pretest mean = 1.84; posttest mean = 3.62), though these findings are descriptive and do not imply causality. The findings from this mentoring activity indicate a transformation in participants’ awareness from a passive relationship with environmental sounds to the active ability to engage with the sound of a babbling stream, the clinking of carved stones and slices of bamboo as legitimate and articulable artistic materials. The performance produced a soundscape archive documenting the acoustic identity of Ngampel Village in a seven-minute audiovisual format, while also affirming that the integration of natural sounds, movement, and vocals can form a cohesive performing arts ecosystem with the potential to be passed down across generations.
