Every fragrance is a little story that unfolds over hours, and "notes" are how perfumers describe the chapters. Understanding them is the single most useful thing you can learn as a buyer — it's the difference between guessing and knowing whether a scent (or a dupe of it) will actually work for you.
The three layers: top, heart, base
A fragrance is built in three tiers that reveal themselves in sequence. Top notes are the opening — bright, volatile things like citrus and herbs that you smell for the first few minutes, then fade. Heart notes (or middle notes) are the character of the scent — florals, fruits and spices that carry the main theme for a few hours. Base notes are the foundation — rich, heavy materials like woods, amber, musk and vanilla that linger longest and become your "skin scent."
This is why a perfume smells different an hour in: you're moving from the top, through the heart, into the base. It's also why sampling on skin matters — the bottle only ever shows you the opening.
What's an accord?
An accord is a blend of notes that reads as a single impression — the way flour, butter and sugar stop being separate ingredients and become "cake." When people say a fragrance is a "warm amber" or a "fresh aquatic," they're describing its dominant accord. Accords are how we match scents on Dupejoy: two fragrances that share the same core accords smell alike, even at very different prices.
Why notes decide whether a dupe works
The payoff: a dupe works when it shares the heart and base notes of the original — the parts that become your signature — not just a similar opening. That's the entire basis of a good match. When we say a dupe shares "key notes," we mean the recognisable heart and base accords, which is why it reads so close on skin even though it isn't identical.
