In short
You can learn a great deal from a fragrance you admire by smelling it closely over time, describing its structure and effects, forming hypotheses about how it's built, and then composing your own response to one idea in it. That's different from copying. A study records what you perceive and takes the idea somewhere else, while a copy tries to reproduce the fragrance itself, and may be passed off as such. The fragrance matching guide covers matching as a skill, and this lesson concerns what you do instead when the aim is to grow.
What you will learn
- Analyze a fragrance's structure and effects by nose
- Tell a study from an imitation
- Write an original response to a studied fragrance
Before this lesson: Composing Under Constraint
An analysis method
- Wear or strip it. Commercial fragrances that you normally wear are fine on skin. Use a strip as well, and compare the two.
- Time course. Record at 5 minutes, 30 minutes, 2 hours, 6 hours and the next day.
- Divide it. Name what you perceive at each stage, in plain language first, and then in terms of families and materials.
- Hypothesize. "The opening seems to be citrus lifted by an aldehyde." Mark each one as a guess.
- Test a hypothesis. Smell a candidate material beside the fragrance. Does it fit?
- Find the idea. In a sentence, what is the fragrance trying to do? What is unusual?
- Find the mechanism. What might be creating that effect?
Four kinds of question
| Kind | Example |
|---|---|
| Structure | Is it linear or does it evolve? Where does the main character arrive? |
| Proportion | What dominates? What is surprisingly small? |
| Contrast | Where's the tension? What keeps it from being simple? |
| Restraint | What did they leave out, compared with others in the family? |
What your nose can and can't tell you
You can't read a formula from a smell. People identify only a few parts of a mixture, as mixture research shows, and materials can stand in for each other. Instrumental analysis gives more clues but no formula either, as you found in reading GC-MS reports. So stay modest. "It smells like a large Hedione with a clean musk" may be useful without being true. Keep a difference between impression and fact in your notes.
Where learning stops and copying starts
| Activity | General view |
|---|---|
| Smelling and analyzing, privately | Ordinary learning |
| Practice matching, kept private and labeled as such | A traditional training exercise |
| Using an idea or a technique in your own distinct composition | How the field has long developed |
| Selling something as "inspired by" with a brand's name | A trademark and advertising risk; take advice |
| Passing off a match as the original, or copying packaging | Don't do it |
Respect people, too. Saying "my homage to X" in your marketing can be a claim someone might challenge. Keep your study notes factual, and don't publish anything claiming to reveal a commercial formula.
Responding
A good response takes one idea and changes its context. For instance, if a fragrance you admire uses a cold metallic note against a warm floral, you might try a cold metallic note against a warm spice, using materials from your own palette. Don't begin with its formula, or use its name in yours. Compare at the end: does yours say something of its own? Have someone smell both blind, and ask whether they seem related, and which they'd choose. If they say "the same", you've copied the fragrance, even without meaning to, so change direction.
Practical exercise: An analysis and an original response
- Choose one commercial fragrance you admire, and buy or sample it legitimately.
- Analyze it using the seven steps, in at least two sittings. Label every guess.
- Test at least three hypotheses against materials on strips.
- Write what you take to be its central idea.
- Compose an original response using one idea, keeping full logs. Check your materials for restrictions.
- Have someone compare them blind, and describe how they relate.
You have done this well if your analysis separates impression from fact, your composition isn't mistaken for the original, and you could explain what's yours.
Common mistakes
- Believing you've found the formula. You have a hypothesis.
- Starting with a published "dupe" list. It teaches you very little.
- Using a brand's name to sell your work. Take advice first.
