Words that help us understand scent
The more I work with fragrance, the clearer it becomes how important language is in telling its story.
The world of scent is not complicated because it is elite or inaccessible — it becomes complicated when we lack the words to describe what we feel.
This text is a small perfumery dictionary: a collection of core concepts you can return to when questions arise:
Why does this fragrance change?
Why do I perceive it differently from others?
Why do some scents fade quickly while others stay for hours?
Top, Heart, and Base Notes
This is one of the most frequently used — and often misunderstood — concepts in perfumery.
Top notes are what we smell first. They are light, volatile, often fresh: citrus, green notes, ozonic impressions. They create the first impression but disappear relatively quickly.
Heart notes (or middle notes) form the core of the fragrance. They emerge once the top notes soften and define the character of the scent. This is where you often find florals, fruits, and spices.
Base notes are the foundation. They remain the longest on the skin and give the fragrance depth, warmth, and presence. Woods, resins, musks, amber, vanilla.
It's important to understand that these are not three separate fragrances — they are different stages of one scent unfolding over time.
The Fragrance Pyramid
To better visualise this development, perfumery often uses the concept of the fragrance pyramid. It's a visual tool that helps explain how a scent behaves after application.
At the top of the pyramid are the top notes — light, volatile, and immediately noticeable. They attract attention but fade the fastest.
In the middle are the heart notes — the identity of the fragrance. This is when the scent feels most stable and recognisable.
At the base are the base notes — the structural support of the fragrance. These materials are heavier on a molecular level, more persistent, and remain on the skin the longest. The base often determines how a fragrance is remembered over time.
The pyramid is not a strict rule but an orientation. In reality, notes don't switch on and off — they overlap, blend, and interact. Sometimes base notes are noticeable from the very beginning; sometimes top notes echo much later.
The pyramid helps us understand one essential thing: fragrance is not static. It is a process.
Accords
An accord in perfumery is similar to a musical chord — a combination of materials that together create a single, recognisable impression.
For example:
- a leather accord
- a marine accord
- a white floral accord
An accord is not a single ingredient. It is a sensation. It's a way for the perfumer to structure an idea rather than list materials.
Raw Materials vs. Notes
This distinction is essential.
Raw materials are real substances: essential oils, absolutes, resins, aroma molecules.
Notes are what we perceive.
One note can be created using dozens of different materials. And one material can express multiple notes depending on context.
That's why rose in perfumery is never just "rose." It can feel fresh, green, dark, honeyed, metallic, or even smoky.
Fragrance Families
To make scents easier to navigate, they are grouped into fragrance families. Some of the most common are:
- Citrus – fresh, bright, sparkling
- Floral – from transparent to opulent
- Woody – dry, warm, structured
- Oriental / Amber – warm, sweet, resinous
- Green – leaves, stems, fresh bitterness
- Fougère – lavender, moss, aromatic greenery
These families are not rigid categories. Many fragrances live somewhere in between.
The Fragrance Wheel
The fragrance wheel is a visual tool that shows how scent families relate to each other — which are close, which contrast.
It's useful both when choosing fragrances and when creating new combinations. If you enjoy one area of the wheel, you're likely to enjoy neighbouring zones as well.
Longevity
Longevity refers to how long a fragrance remains noticeable on the skin.
It is influenced by:
- concentration (EDT, EDP, etc.)
- base notes
- skin chemistry
- environment and climate
It's worth remembering that longevity does not automatically mean quality. Sometimes the most beautiful experience is a fleeting one.
Sillage (Projection)
Sillage describes how far a fragrance travels in the air.
Some scents are intimate — noticeable only up close.
Others leave a trail behind them.
Neither approach is better. It's a matter of context, culture, and personal boundaries.
Why These Words Matter
Because they give freedom.
When you can name what you feel, fragrance becomes a conversation rather than a guess.
Perfumery is not about right or wrong. It's about attention, experience, and relationships — with yourself, with your surroundings, with memory.
