Hercule Florence and the Birth of Zoophony

In the 1820s and 1830s, long before microphones and portable recorders, one man tried to catch the living world with nothing but attentive ears and a notebook. His name was Hercule Florence. Born in France in 1804, he left Europe young and built his life in Brazil, where he became a draftsman on a major scientific expedition through the interior. He was the kind of observer who never stopped taking notes: landscapes, people, plants, animals, and the small details that most travelers miss. Back in São Carlos after the expedition, he kept inventing, sketching, experimenting, and documenting, moving naturally between art and science. Among his many ideas, one stands out for anyone fascinated by sound: zoophony.

Zoophony emerged from a simple, powerful frustration. Florence was surrounded by a sonic wilderness: birds calling across the canopy, mammals answering in the distance, insects weaving constant rhythms into the air. But how do you keep those sounds? How do you share them with someone who was not there? Words like “chirp” or “howl” felt too vague, too blunt, like painting a sunset with a single color. Florence wanted a more precise memory, something closer to what the ear truly receives.

So he turned to writing, and more specifically to the logic of musical notation. If music can be preserved on paper, why not the voices of animals? His approach was not mechanical recording, but structured transcription. He aimed to translate what he heard into marks that could suggest pitch, duration, rhythm, repetition, and phrasing. In other words, he tried to make sound visible and comparable, to build an archive of animal calls that could be studied later, side by side, like specimens in a cabinet.

This is the key: zoophony was an attempt to “record audio through writing”. It treated sound as information that could be captured, stored, and revisited. Today, bioacoustics relies on recordings, spectrograms, and software analysis. Florence did not have any of that, yet the impulse is strikingly similar: listen carefully, extract patterns, document them, and use them to understand behavior and ecology. His paper-based method could not reproduce timbre the way a recording can, but it aimed at something equally ambitious for its time: preserving the structure of a voice, not just the impression it leaves behind.

Zoophony reminds us that the history of sound is not only a history of machines. It is also a history of listening, of notation, of people who tried to hold onto what disappears the instant it is heard. If you had to invent your own way to write down a sound you love, what would it look like?
