In short
A concept becomes a formula in three moves: translate the idea into specific smell targets you can compare with a strip, assign each target a job in the composition, then choose materials for each job, leaving out everything that does not serve the idea. Most first drafts fail because they start from favorite materials instead of from a concept.
What you will learn
- Translate abstract words into testable smell targets
- Draft a formula from jobs rather than favorite materials
- Decide what to leave out
Before this lesson: Working a Formula in the RUŌOD Lab App
Step one: turn words into smell targets
Adjectives such as elegant give you nothing to test. Convert them into things you can actually smell or vividly recall. "Rain on hot pavement." "A cedar box with old letters." "Orange peel on a wool coat." If you can obtain the real thing, keep it nearby, or write down what it smells like before you start composing. This is the point of the brief you wrote in Level 1. Return to it now.
Step two: assign jobs
List what the composition has to do, at each stage of its life:
| Stage | Job | Target | Candidate family |
|---|---|---|---|
| Opening | Cold, damp air | Wet stone | Metallic-aldehydic trace, green |
| Heart | Green-earth body | Moss, wet bark | Mossy synthetics, vetiver at low dose |
| Drydown | Quiet resin | Old incense | Frankincense, soft woods, a dry musk |
Published work can suggest how others handled something similar. The stone nave and moss cathedral are worth reading, but read them after you have written your own plan, not before.
Step three: choose materials you know
For each job, choose from materials you have actually studied. A draft full of materials you have only read about is guesswork. Keep to six to ten lines at first. You can always add, but you will not learn from a thirty-line first draft.
Step four: draft proportions by size of job
Start by budgeting rather than computing: the main idea may take a large share, supporting parts less, traces tiny. Use accords from Level 4 as single lines where they fit. Your first numbers will be wrong, and that is expected. They exist so that there is something to correct.
Reject and protect
Write down what the fragrance must not be: "no sweetness", or "not a cologne". Check every addition against that list. A concept is mainly a tool for saying no, particularly to a beautiful material that does not belong in this fragrance. If you love it, save it for another idea.
Be honest about what it will become
Concepts drift as you work. If a formula becomes something else that is better, you can follow it, but then you should rewrite the concept, so that later decisions are still tested against something real.
For the mechanics of building and revising, read how to create a perfume formula. The Journal's architecture of a fragrance gives the same structure from a reader's side.
Practical exercise: From one sentence to a first draft
- Write your concept in one sentence, using nouns you can smell.
- List at least three smell targets. Write what you can compare each with.
- Fill in a jobs table for opening, heart and drydown.
- Choose six to ten lines from materials you know, and rough out their shares so that they total 100.
- Write the "must not be" list. Check your draft against it, and remove anything that fails.
You have done this well if every line serves a stated job, and another person reading your concept could say whether a given strip fits it. You do not need to weigh it yet.
Common mistakes
- Starting from your favorite material. You get that material and some decoration.
- Concepts made of adjectives. You cannot test whether something is "sophisticated".
- Too many lines. Every extra line makes the next correction harder to interpret.
Key terms
- Smell target
- A specific smell, real or remembered, that a composition is trying to evoke, as opposed to an abstract adjective.
