Somewhere in Britain, a mushroom is making music. Not metaphorically, not as a marketing stunt. A fungus, wired with electrodes, is generating signals that move a robotic arm across a keyboard.
Before you file this under “things the internet invented,” know that the science underneath it is real, peer-reviewed, and genuinely unsettled.
The Setup Is Exactly What It Sounds Like
Custom bionic arms, a synthesizer, and a living organism that has no idea any of this is happening.
Engineer Jon Ross built custom bionic arms for the bio-art collective Bionic and the Wires. Those arms detect small fluctuations in electrical conductivity across a mushroom or plant and convert those shifts into control data that drives the robotic arm across a MIDI keyboard.
The mushroom does not press the keys. The machine does, using the fungus’s bioelectrical shifts as its instructions.
Think of it less like a musician and more like a very slow, very organic theremin, except the theremin has absolutely no idea it’s performing.
Real Signals, Carefully Defined
Fungal mycelium does produce measurable electrical activity, and scientists are precise about what that means and what it does not.
Fungal mycelium produces measurable electrical signals. Researchers have documented low-voltage, low-intensity currents associated with hyphal activity and shifts in the surrounding environment.
Those signals have not been shown to be equivalent to animal nerve impulses. A peer-reviewed review published in a scientific journal notes the currents are “either of low intensity or low voltage, resulting in values lower than those that have been observed along animal neurons.” The available research does not establish human-like thought or cognition in mushrooms.

Environmental conditions can affect fungal electrical measurements and may complicate interpretation. Moisture, temperature, and other factors in the room can shift the patterns the system picks up, so the resulting music reflects more than just the biology of one fungus.
Artistic Interpretation vs. Established Fact
Bionic and the Wires frames the project as evidence of natural intelligence; science frames the signals as interesting electrical activity with unclear meaning.
Bionic and the Wires states the project “explores the intelligence and responsiveness of the natural world by transforming bio-electrical signals into” music and visual art, according to its official website. (Note: the quotation is reproduced here as supplied; verify the complete wording against the original page before publication.) That framing is an artistic interpretation, and it is a legitimate one for a bio-art project to hold.
Research confirms that fungi can produce measurable electrical activity. It does not confirm the mushroom is communicating, composing, or displaying anything resembling cognition. The communicative function of these signals remains an active area of study, with no settled answer yet.
That distinction is worth holding onto.
Agency, Translation, and What Gets Lost Between the Two
The mushroom is not the artist, but neither, entirely, is the human, and that ambiguity is the point.
The project presents itself as an artistic exploration rather than a scientific demonstration of fungal thought. It surfaces biological activity that is normally invisible and routes it through a human-built translation system until it becomes sound you can hear in a room.
What you are left with is a genuinely uncomfortable question: if creativity requires intent, where does the mushroom’s role end and the machine’s begin? The project does not answer that. It just makes the question audible.
That might be enough.
