The 12 fragrance accords
Notes vs accords · what is the difference?
A note is a single ingredient or material · a specific extract (rose absolute, sandalwood oil) or a specific synthetic molecule (vanillin, Iso E Super). When perfumers list "top notes" or "base notes" on a fragrance pyramid, they are listing the ingredients used.
An accord is the composed effect produced when several notes blend into a coherent scent character. The "leather" accord, for example, is not made from leather · it is constructed from notes like isobutyl quinoline, labdanum, styrax, and birch tar that, blended in particular proportions, produce the olfactory perception of leather.
Accords are the building blocks of fragrance composition. A perfumer thinks in accords (a powdery iris accord, a smoky woody accord, a fresh citrus accord) and selects notes to construct each accord. The fragrance you wear is the layered result.
