In short
Contemporary perfume techniques include dissonance, abstraction, material portraits and deliberately unbalanced structures. None is new in principle, and none is automatically good. They are ways of breaking habits on purpose. A technique earns its place when you can state your intent, and when a person who has not heard your explanation gets something from the result.
What you will learn
- Describe four contemporary compositional approaches
- Choose a technique for a stated intent
- Test an experimental idea on someone without explaining it first
Before this lesson: Evaluating an Unfamiliar Material
Four approaches
| Approach | The idea | The risk |
|---|---|---|
| Dissonance | Two things that seem not to belong: a sweet milk with a metallic note, say | It reads as a mistake or a contaminant |
| Abstraction | Evokes a place, material or state, without reconstructing it: hot stone, cold air | Only you can read the reference |
| Material portrait | One material at the center, with supports that reveal its facets | Becomes an expensive dilution of one thing |
| Unbalanced structure | A long top with little base, or an all-base opening | It simply feels unfinished |
Contrast with a job
You studied contrast in contrasting notes, where the question was how much tension a simple pair could carry. In a full composition, dissonance needs something that unifies it, such as a shared musk or a recurring note across the stages. Without one, the two ideas may separate on the skin. Test across time: a pairing that is interesting at 15 minutes may become unpleasant at 3 hours.
Abstraction and its audience
A person can only recognize an abstract idea through something they have smelled. So a "hot stone" may depend on the mineral quality of certain ambers, plus dryness and warmth from materials you have studied. Often the most helpful question is: what are the two or three cues that would make someone think of this? Then you can build those, and leave the rest out. See the concept work in concept to formula.
A material portrait
Pick a material you know very well, such as Cashmeran. List its facets as you experience them. Choose a small support for one facet at a time. Then decide which facets the final composition should show first, and which should come later. Our Cashmeran guide shows how to analyze a single material in depth, and your earlier card from evaluating a new material is exactly the raw information you need.
Breaking a rule on purpose
- Write the convention you are breaking, for example, "A fragrance needs a clear top note."
- Write the reason you are breaking it, and what it should give the wearer.
- Make the rule-breaking version, and a conventional control.
- Ask for reactions without explanation.
- Decide whether the break gave you the result, or whether you simply lost a useful thing.
Testing without explaining
Once told an idea, most people will try to find it. So ask first: "What does this make you think of? Where would you wear it? Is there anything you dislike?" Tell them your concept only afterward, and ask whether it fits. Some disagreement is fine, because experimental work divides people. But "it smells like a mistake" from several people deserves careful attention, whatever your concept.
Practical exercise: One deliberate rule-break
- Choose one approach from the table, and write your intent in two sentences.
- Make a small composition of no more than 15 materials, plus a conventional control. Check any restriction first.
- Compare over 8 hours and at 24 hours.
- Ask at least two people for their reactions, using the questions above, before explaining anything.
- Write a short critique of your own composition: what it attempted, what happened, and what you would change.
You have done this well if your intent was written before you started, and you recorded the reactions faithfully even where they disagreed with your idea.
Common mistakes
- Calling a failure "challenging". Check for intent, unity and reactions first.
- Explaining before testing. You will only learn what you told them.
- Experimenting with restricted materials to get an effect. The experiment does not suspend the rules.
