Why scents have a sound – The fascinating connection between perfume, music and colors

Why do perfumers talk about fragrance notes, fragrance accords, or fragrance compositions? Why is a workstation in a laboratory called a fragrance organ? And why do many people automatically see yellow or green in their mind's eye when they smell a lemon?

What might sound unusual at first actually has a long tradition. The world of fragrances is much more closely connected to music and colors than most people suspect. Anyone who delves deeper into the art of perfumery quickly realizes that fragrances aren't just smelled – they can also, in a way, sound and even evoke colors.

Why scents and music speak the same language

Anyone who takes a look inside a perfumer's laboratory will discover hundreds or even thousands of different fragrance raw materials. These are neatly sorted on shelves and have been referred to as a "fragrance organ" for centuries.

The term didn't come about by chance.

Just as an organist combines different registers, a perfumer blends various scents into a harmonious composition. Therefore, a large part of the technical terminology comes directly from music.

There are fragrance notes, accords, harmonies, and compositions. No perfume is created by chance. Each individual ingredient performs a specific task – just like an instrument in an orchestra.

A perfumer often works much like a composer. Before the first pipette is even used, the actual fragrance idea is first conceived in the mind. There, various scents are mentally combined until a harmonious overall impression emerges.

Only then does the practical work in the laboratory begin.

Fragrances consist of a musical composition.

Every classic perfume follows a similar structure. It is referred to as a fragrance pyramid with top, middle, and base notes.

Comparing this structure to a piece of music quickly reveals why fragrances are so often described musically.

The top note is the first impression. It's reminiscent of a song's intro. Fresh citrus notes like bergamot, orange, or lemon sound lively, light, and attention-grabbing. Just like the high notes of a flute or violin, they appear immediately but also disappear relatively quickly.

The heart note then takes center stage. It carries the true melody of the fragrance. Floral scents like rose or jasmine, as well as spicy components, often define the character of a perfume for many hours.

The base note forms the final layer. It develops more slowly and lasts the longest. Woods, patchouli, musk, amber, or vanilla lend a fragrance depth, warmth, and stability. In an orchestra, this would correspond to the deep sounds of a cello, double bass, or timpani.

The real art lies in blending these individual fragrance phases so harmoniously that no harsh transitions occur. Just like in a good piece of music, there should be no breaks in the fragrance.

Why scents create colors

Music isn't the only important factor when it comes to fragrances.

Many people automatically associate smells with colors. For example, when we smell a freshly cut lemon, very few people think of black or brown. Instead, yellow or green tones almost automatically appear in our mind's eye.

This phenomenon is scientifically known and is called synesthesia.

Our brain connects different sensory impressions. A scent can evoke colors. Conversely, colors or music can also trigger memories and feelings.

This connection is used daily in the perfume industry.

Pastel fragrances appear soft, light, and creamy. Fruity fragrances often seem colorful and vibrant. Dark, woody, or smoky fragrances, on the other hand, are frequently associated with brown, gray, or black tones.

Whether consciously or unconsciously, our brain automatically creates images of scents.

Fragrances thrive on contrasts.

Interestingly, perfumers work not only like composers, but also like painters.

A painter often uses complementary colors to make certain areas stand out. A vibrant red appears more intense next to green than on its own.

The same principle applies to fragrances.

A bright, elegant jasmine note gains significantly in expression when it meets a dark base of patchouli, leather, or oud. Only this contrast allows the floral fragrances to unfold their full radiance.

Without antagonists, many compositions would appear flat and one-dimensional.

That's why particularly exciting fragrances often arise precisely where opposites are deliberately combined.

Researchers were already studying scents and music over 100 years ago.

The connection between music and scents is by no means a modern idea.

As early as the beginning of the 20th century, the French perfume historian Septimus Piesse intensively studied this topic. He was convinced that fragrances function similarly to musical vibrations.

From this consideration, he even developed a theoretical instrument – the so-called odophone.

The idea was fascinating: instead of producing sounds, each key would release a specific scent. High tones corresponded to light, fleeting fragrances, while low tones represented heavy and long-lasting scents.

Even though this instrument never gained practical importance, its way of thinking still influences modern perfumery today.

Perfumers still talk about fragrance accords and harmonies.

Fragrances appeal to our emotions.

Perhaps the most important reason why fragrances are so closely compared to music lies in their effect.

A song can evoke memories within seconds. Suddenly you think of a vacation, a special person, or a particular period of your life.

The same thing happens with fragrances.

A hint of sunscreen instantly evokes memories of a recent beach vacation. Freshly cut grass brings back childhood memories. The scent of vanilla conveys a sense of security, while citrus notes radiate energy and freshness.

Music and scents both stimulate the same area of our brain – the limbic system.

That's where emotions, memories, and moods are created.

That is precisely why scents often have such an intense effect, even though we often only perceive them subconsciously.

Why fragrances are far more than just pleasant smells

Many people view perfume simply as a pleasant smell.

However, there is actually much more to it.

A carefully crafted perfume is simultaneously a piece of music, a painting, and an emotional storyteller. It possesses a captivating opening, a compelling middle, and a long, lingering aftertaste. At the same time, the scent evokes images, colors, and memories.

Every fragrance tells its own unique story.

Perhaps this is precisely why some scents remain in our memory for decades, while others are forgotten after just a few minutes.

The language of perfumery impressively demonstrates that fragrances can never be considered in isolation. They combine scent, music, colors, and emotions into a single, unified work of art.

Anyone who applies perfume or consciously smells a fragrance in the future can try paying close attention. What colors appear in your mind's eye? What mood does the scent evoke? And what piece of music might be the perfect complement?

Perhaps you will discover for yourself why scents can actually sound.
