Music performed by a plant

According to the posted description:

The music in this recording has actually been performed by a plant, Anthurium (anthurium andreanum), thanks to a specific electronic device. Plants emit signals in reaction to external stimuli and to communicate with everything. These signals are detectable as variations in the bio-electrical field of the plant and can be converted into a MIDI signal (Musical Instruments Digital Interface). I sent this MIDI signal into a synthesizer and programmed a soft, soothing sound tuned at 432 Hz. After some time being connected to such device and producing sounds, plants seem to become aware of the process; they seem to understand that those sounds are coming from them... and they start playing with it.

The video is longer than an hour but quite pleasing to the ear.
