The Odor Organ is a compact diffusion device that delivers odor notes in synchronicity to music keys; it allows you to play scents instead of sounds

As a society, we favor sight and often ignore this rich olfactory information. Although not everyone is, humans evolved to be capable of perceiving and communicating this information.  

Being able to have a more acute understanding of smell will allot us a more clear understanding of our surroundings, our environment, our bodies, our health, our memory formation and recall. Scent can tell you about the genetics of those around you, the species in your local ecosystem, about disease and danger; it holds the traditions and foods of a culture. 

So here lies my mission: help people increase their olfactory literacy, but how?
Scent is a wonderful well of information, but as a medium involving chemistry, artistry, neuroscience, perception, physiology, genetics, biology it can be a pretty intimidating field to approach, but it really doesn’t have to be.

Play provides such a fun, joyful, low friction access point into learning, specifically with complex ideas like olfaction. This is the direction I wanted to channel my efforts toward - empowering others to follow their own curiosity into the world of scent .

There is a longstanding parallel between scent and sound; it is present in the temporal quality, in the subjective nature, and even in the language used to describe scent. Some common terms in scent practice: notes, accords, harmonies, perfumer’s organ.

Through this project, I wanted to use this correlation to my advantage. I chose to use the actual mechanisms of music making - specifically the form of a piano. This form is so familiar to us from grand piano’s in concert halls to the toy pianos given to children. This makes it an intuitive and non intimidating entry point to play.

Background

In the history of scent art, there have been a few attempts at equating musical notes to scent notes. Most famously, Septimus Piesse took the musical scale and mapped scents to each note of a piano which you can see on the left.

In 1922, artist Frank R. Paul, inspired by Piesse’s work, illustrated a theoretical "smell organ," a device which could play the scented scales but it was never actually fabricated. It did inspire other artists, and since then, there have been a few iterations of this concept. Like the image on the right though, these iterations primarily cater to an audience of many.

Unlike these multi-sensory experiences, the Odor Organ does not demand or reward larger numbers of people. This device is optimized for the player. They receive the scent first and will perceive the changes in the scentscape in the highest amount of detail.
