To experience INSIDE, you connect yourself to a heartbeat sensor via 3 ECG stickers. The sensor sends data about your electrical heartbeat to a teensy 3.6, that is coded to map the interval between your heartbeats. It then calculates how coherent the rhythm is, based on your last 10 beats. A coherent heart rhythm corresponds to a peaceful state, where an incoherent rhythm corresponds to a state of frustration, anxiety, etc. From this, it generates music: a coherent rhythm will create harmonious music, an incoherent rhythm disharmonious music. -based on scales, chords, wavefunctions, and timing.
