When the receptors interact with molecules, they set off
a chain reaction that ends by sending a message to our
brains.

What’s the smell of Coca-Cola? Or Chanel No. 5? The
answer, again, isn’t a list of molecules. “It’s a
pattern of receptor responses,” says Aromyx founder Chris
Hanson.

Each receptor, their research showed, is uniquely primed to
react to a few different molecules, and our noses sense
distinct odors when many receptors fire at the same time.
John Kauer, then a researcher at Tufts University, relates
the idea to playing chords on a piano. “The piano only has
88 notes,” he says. “If you were only able to use one
note per odor, you could only detect 88 different odors.”
If odors are more like chords, then the math suddenly works
out.

molecule’s shape, in other words, is not synonymous with
its smell. Instead, many receptors bind to many different
molecules and vice versa. But each receptor has what some
scientists call a distinct “affinity” for each molecule.
It’s that special affinity, the theory now goes, along
with the combinatorial nature of olfactory reactions, that
accounts for unique scents. The piano doesn’t just have 88
keys that can form chords; it also has pedals and dynamics.
“You hit piano keys at different strengths, heavy and
light and so on,” Zhang says. “Heavy, you get one sound;
light, you get another sound.” Or to put it another way:
The theory of smell just gets more complicated.

it's actually like the difference between notes on a page
and the act of perceiving music.

smell is not a combination of molecules, but your reaction
to that combination of molecules.
music is not sound, it is your reaction to sound
