“During a small lecture at a private residence in Delray Beach earlier this month, I watched a houseplant play music, unabashedly and beautifully. Potted and still, it was hooked up to a MIDI machine via electrodes, its bio-emissions creating twinkling melodies. Attached to the same machine, an orchid and rosemary plant played nothing, but this one was active and virtuosic, as though it enjoyed playing.” A reporter talks to a leader of the Music of the Plants project about how all this works.
