The Two Axes: Family and Note
Almost every confusing fragrance description resolves once you realize it is describing two different things at once. A family is a category of overall character — woody, citrus, chypre. A note is an individual smell within a composition — vetiver, oud, bergamot. Families are made of notes, and the same note appears across many families.
So a fragrance can be a woody chypre containing vetiver and oakmoss, and none of those three words is redundant. The family tells you the shape; the notes tell you the ingredients; the way the notes are arranged tells you how it will behave on skin over four hours.
This site treats both axes as first-class. The families index explains where each category came from and what unites it. The notes index describes what each raw material actually smells like, in plain sensory language rather than in the abstract adjectives the industry prefers.
How to Read a Note Pyramid Without Being Misled
Fragrance is usually described as a pyramid of top, heart and base notes, corresponding roughly to what you smell in the first fifteen minutes, the following few hours, and what remains at the end. It is a genuinely useful model with two well-known problems.
- Pyramids are marketing documents. They list what sounds appealing, not what is in the bottle in quantity. A pyramid naming twelve notes is describing an impression, not a formula.
- Modern perfumery is often not built in three tiers at all. Many contemporary compositions are close to linear by design and smell similar from the first spray to the last hour. That is a stylistic choice rather than a defect.
The practical approach is to read the pyramid for the two or three notes that dominate, ignore the decorative ones, and then read about those materials specifically. What fragrance notes actually mean covers the model and its limits in full.
Concentration, Longevity and What Actually Varies
The letters on the bottle — EDT, EDP, parfum — describe the concentration of fragrance oil in alcohol, and they are the most misunderstood thing in the category. A higher concentration usually lasts longer, but it is not simply a stronger version of the same thing: the formula is frequently rebalanced between concentrations, so an EDP and an EDT of the same name can smell noticeably different.
Longevity is also driven far more by the raw materials than by the percentage. A citrus-dominant fragrance will fade quickly at any concentration because citrus molecules are volatile; a base-heavy woody amber will persist for a working day even in a light concentration. Fragrance longevity covers why, and what you can actually do about it.
If you are choosing between two bottles of the same scent, EDP vs. EDT settles it. If you are trying to work out why the same fragrance behaves differently on you than on someone else, sillage vs. projection is the page that explains the vocabulary.
