Spray a perfume and smell it again after ten minutes, then after three hours. It will not smell the same – and that is by design. Perfumers build fragrances in layers that evaporate at different speeds. This structure is called the fragrance pyramid.
Top notes: the first impression
Top notes are the lightest, most volatile materials. They greet you on the first spray and typically fade within 15–30 minutes. Common top notes include bergamot, lemon, grapefruit, pink pepper, mint and light fruits. Their job is to make an introduction and lead you into the heart.
Heart notes: the character
Also called middle notes, these emerge as the top notes lift and form the main body of the fragrance for several hours. Rose, jasmine, orange blossom, lavender, cardamom, cinnamon and green notes often live here. If you describe a perfume as “floral” or “spicy”, you are usually describing its heart.
Base notes: depth and memory
Base notes are the heaviest materials and anchor the whole composition. They can last many hours on skin and linger on clothes. Think sandalwood, cedar, vetiver, patchouli, musk, amber, vanilla, tonka and – especially in Arabian perfumery – oud.
Why the pyramid matters when you buy oils
- Longevity depends heavily on the base. A citrus-heavy oil will feel fresher but shorter; a woody-amber oil will last longer.
- Season and occasion follow the pyramid: bright tops for summer days, rich bases for evenings and winter.
- Layering works best when you pair oils whose heart and base complement each other.
Accords: notes working together
Perfumers rarely think in single notes. They build accords – groups of materials that blend into a new impression, such as a “leather” accord or a “sea breeze” accord. Every Haveli AI oil is listed with its main accords and notes so you can compare quickly.
