Inspired by Fluxus musician Ben Petterson’s score, trying to make a score composed of pencil drawing. Due to the graphite’s conductivity, so that Arduino can detect the different amounts of voltage in each density of graphite drawing. I already measured of frequencies of each density can make, intend to compose it as a score. The result will be made as a form of a stethoscope for drawing, the participant can hear the sound interpreted from the drawing elements. The score is designed by drawings, that can be directly interpreted into a musical note.
