The Plant Choir™ system comprises a software program and hardware that measures electrical activity of a person, plant, or animal and translates those readings into music on a computing device. The system gathers electrical activity data using electrodermal activity (EDA) measurement devices. The EDA readings of the individual subjects are translated via the software into musical melodies in real time. The individual subject melodies are combined to create interesting harmonies similar to a choir. The music is rendered using a MIDI (Musical Instrument Data Interface) programming interface of the computer operating system. The software allows the user to select program options, set music and program parameters. Variations in the EDA signal are interpreted as music. Each subject connected to the system is assigned a musical voice and the voices are combined to create multi part harmonies similar to a choir.
