Identify dominant and supporting notes | SESH Academy
SESH · Intermediate Fragrance Academy
Separate leading, supporting and background impressions at different timepoints.
Vanilla pods are a real botanical source. A vanilla note can be created with different materials and does not prove the presence of pods or extract.

Dominance isn't the largest percentage
A small amount of a potent odorant may dominate perception even when another material is present at a much higher proportion. 'Dominant' describes what you notice most clearly, not necessarily the ingredient at the highest concentration. Mixture interactions and differences in sensory sensitivity both affect prominence.
Three roles in one sniff
Write the strongest impression first: for example, sweet fruit. Then search for a modifying quality such as tart freshness or a powdery veil. Finally identify a quiet background facet such as a soft woody warmth. A supporting aspect can transform the overall effect without becoming the main identifiable note. If unsure, describe the effect rather than inventing a material.
Prominence shifts as the fragrance develops
Imagine a bright citrus opening with a subtle rose impression. One hour later citrus may recede and rose can feel more prominent. The rose was not suddenly added to the formula; the mixture's perceived balance changed. Rate each discernible facet at 5, 30 and 120 minutes, keeping the test conditions as similar as possible.
Citrus peel and flesh are different parts of the fruit. Use this as a sensory reference, not a way to infer a formula from a note name.
Avoid leading yourself
Reading that a perfume has jasmine can prime you to search for jasmine even if you only detect a generic floral accord. Smell blind where practical, and tag observations as confident, tentative or uncertain. Recording uncertainty produces stronger notes than matching every advertised descriptor.
Case: a sparkling opening and soft dry-down
In a hypothetical test at five minutes, you rate citrus 4/5, floral 2/5 and soft woods 1/5. At one hour citrus is 1/5 while floral and woods each reach 3/5 in perceived prominence. The lead impression has shifted, but that does not mean the bottle acquired more wood molecules. Evaporation, masking and sensory sensitivity change the balance reaching your nose. Keep observation times consistent and do not compare scores from different doses as though they were directly equivalent.
Don't force every advertised note into your notes
A note pyramid can prime you to detect every named facet. Make an independent blind description, then use the published list as possible interpretations rather than a required answer key. If a facet is subtle, say so; if it is absent from your perception, report that uncertainty. Sensory skill is not a competition to name the most notes.
Practical exercise
On one blotter, assess the same fragrance at three checkpoints. Record leading, supporting and background characteristics, marking uncertain observations with a question mark.
Comparison guide
Three levels of prominence
- Lead: first unmistakable facet
- Support: modifies the character
- Background: subtle supporting presence
A shifting perceptual balance
- 5 min: clear citrus
- 30 min: balanced floral
- 2 hours: soft woody
