A perfume is built with science, memory and sensitivity. Behind every fragrance is a precise architecture made up of olfactory notes, The way we describe the aromas that make it up. Understanding them is like learning to read music: the notes do not sound by themselves, they form chords, and the chords create a symphony.

What are the notes of a perfume?

A note is the smallest perceptible unit within a fragrance. It is not equivalent to a single ingredient, but to how it is perceived olfactorily. For example, the “rose note” does not come only from rose petals: it can be constructed from molecules such as geraniol, citronellol or damascenone.

Notes are the language of perfumery: they translate complex chemical formulas into images understandable to all. So when we say that a perfume has “notes of sandalwood and vanilla”, we are not listing ingredients, but communicating sensations and expectations.

The olfactory pyramid: how a perfume evolves

The classical structure of a perfume is represented by the olfactory pyramid, which organises the notes into three stages according to their volatility.

Top notes

They are the most volatile and fresh: citrus, green herbs, aldehydes. They last only a few minutes, but they define the first impression.
👉 Example: Rosendo Mateu 1 opens with bergamot and green mandarin, a Mediterranean burst that evokes light and energy.

Heart notes

They are the soul of the perfume and often linger for several hours. Flowers, spices and some fruits are found here.
👉 Example: Fleur de Peau by Diptyque is sustained by a powdery heart of iris and magnolia, enveloped by a musk that gives softness and intimacy.

Base notes

They are the most persistent and deepest: woods, resins, musks, leather. They define the trail and the real duration of a perfume.
👉 Example: Eidesis by Aesop rests on a background of sandalwood and incense, creating a contemplative and lasting character.

Main categories of olfactory notes

Beyond time, notes are classified by olfactory families. Some of the most recognised are:

• Citrusbergamot, lemon, orange.
• Floral: rose, jasmine, tuberose.
• Fruit treesmango, red fruits, apple.
• WoodyCedarwood, sandalwood, vetiver.
• Greensleaves, cut grass, galbanum.
• Gourmandchocolate, caramel, coffee.
• AmberVanilla, benzoin, ambergris.
• Muskclean, soft, with hints of leather.

These families help to quickly situate the personality of a fragrance.

When the pyramid breaks

The olfactory pyramid is a didactic tool, but it does not always reflect reality. Many current niche perfumes aim for linear structures, where a complete chord is perceived from beginning to end.

👉 Example: Bergamask by Orto Parisi, constructed solely of bergamot and musk, does not evolve in stages: it projects a raw, direct and persistent chord that defies the classical pyramid.

Why do perfume notes matter?

The olfactory notes are essential for three reasons:

• Olfactory education: they train the memory and help to distinguish families and styles.
• CommunicationThe following are the main features of the perfume: they make it possible to describe complex perfumes in an accessible language.
• Conscious choiceThe perfume's fragrances: they help the consumer to imagine how a perfume will evolve before they try it.

In a nutshell

The notes of a perfume are much more than a list on the box: they are the way we perceive its construction, its evolution on the skin and its character. Whether through the classic structure of top, heart and base notes, or through more modern linear proposals, the notes are still the key to understanding - and enjoying - a perfume. signature perfumery.
