What is Biosonification? How Plants Create Music
Plants don't have mouths, but they're constantly speaking. Every root tip, every leaf edge, every cell membrane is fizzing with electrical activity — ion gradients building and collapsing, water and nutrients flowing, stress responses firing. Biosonification is the science and art of translating those electrical signals into audible sound.
The word itself comes from bio (life) and sonification (making data audible). It sits at the intersection of plant biology, music theory, and data science. The result is music that no human composed — it emerged directly from a living plant.
How Does It Actually Work?
The process starts with measurement. Sensors (usually small electrodes or biofeedback probes) are attached to a plant's leaf, stem, or soil. These sensors detect changes in bioelectrical resistance and surface electrical potential — tiny fluctuations in the millivolt range.
Those raw measurements are fed into a signal processor, which maps the electrical values onto musical parameters:
- Pitch — higher or lower electrical activity maps to higher or lower notes
- Timing — the rate of change determines note duration and rhythm
- Volume — signal amplitude influences how loud each note plays
The result is a real-time MIDI stream. That MIDI output can then be routed to any synthesiser, sample library, or digital audio workstation to produce finished music.
The Devices Making It Possible
Two devices dominate the field today:
PlantWave (by Data Garden) is the most widely used biosonification device. It attaches two electrodes to a plant's leaves, reads the electrical variation across them, and outputs continuous MIDI and audio. The translated signal is typically converted to pentatonic scales to keep the music harmonically pleasant.
MIDI Sprout (also by Data Garden, the older predecessor) works on the same principle. Many artists in the plant music space got their start with MIDI Sprout before PlantWave was released.
Music of the Plants devices, developed by the Damanhur community in Italy, take a similar approach but with proprietary electronics and a particular emphasis on biofeedback and meditation contexts.
What Does Plant Music Actually Sound Like?
The honest answer: it depends entirely on the plant, the environment, and the synthesis choices made by the musician. A cactus under stress produces different patterns than a well-watered fern in full sun.
Broadly, plant music tends to be:
- Arrhythmic — plants don't follow a 4/4 beat; the timing is organic and unpredictable
- Meditative — most practitioners tune their synthesis to gentle, tonal sounds
- Responsive — plants react to light changes, touch, water, temperature, and even human presence
Artist Henotic (featured in the RootNote artist directory) has built an entire catalogue of ambient music by recording extended biosonification sessions with various plants, then layering and mastering the results. The plant provides the melody; the artist provides the production context.
Why Does This Matter?
Biosonification is more than a novelty. It offers:
- A new art form — music that is genuinely non-human in its composition, but emotionally resonant in its result
- A research tool — scientists have used sonification to study plant responses to stimuli, since you can hear stress responses as they happen
- A wellness application — plant music sessions are being used in spas, yoga studios, and meditation centres as ambient soundscapes. See how wellness spaces are using plant music
- A philosophical provocation — if a plant can "make music" through its biological processes, what does that tell us about the nature of creativity?

The Science Behind the Signals
Plant bioelectrical activity is real and well-documented in the scientific literature. Action potentials in plants (similar in principle to those in animal neurons) have been recorded since the 19th century. What biosonification adds is a real-time auditory interface for data that is otherwise invisible.
The signals are genuine — they're not manufactured or simulated. What biosonification introduces is interpretation: the mapping algorithm decides what pitch value corresponds to what voltage, and that choice shapes the character of the music profoundly.
This is why two different biosonification artists working with the same species of plant in similar conditions can produce radically different music. The plant is the data source; the artist is the translator.
Ready to Hear It?
The best way to understand biosonification is to listen. RootNote features artists who work exclusively in this space — real-time and studio recordings of plant music, available to license for commercial and personal projects.
