An accord is a combination of two or more individual ingredients blended together to create a single, unified new smell, one that reads as its own distinct thing rather than as separate notes you can pick apart, much like a musical chord is more than its individual notes played alone.

How Accords Are Built

The “amber” accord discussed elsewhere on our site is a good example, combining labdanum, benzoin and vanilla to create a warm, golden smell that reads as a single recognisable thing, even though none of those three ingredients alone smells exactly like finished amber. Perfumers build up entire fragrances from multiple accords layered and balanced together, rather than working with single raw ingredients in isolation.

Why This Matters for Understanding Fragrance

Recognising that terms like “amber”, “musk” and “oud accord” often describe a blend rather than one single ingredient helps explain why the same named note can smell quite different from one perfume to another. Our guide to perfume basics covers accords in more detail, and our complete guide to perfume ties this into the wider picture of how perfume works.
