We present WireDrum ー a synthetic, multimodal experience that enables motor skill transfer and learning among users. The system consists of multiple custom biosignal-sensing modules, a custom electrical muscle stimulator, a visual and tactile tempo indicator, and muscle-topology configuration software.

By integrating the muscle activities of multiple instructors into a target user's muscles, the user can perform complex physical skills beyond their original ability. Simultaneously, instructors can divide and reduce their cognitive load related to teaching and performing the task.

We demonstrate a shared somatic and interpersonal drumming experience, where a visitor can play a cognitively demanding rhythm that is challenging for novices to perform alone by sharing the visitor's body with other visitors.
