That's not a little contribution but lightyears ahead from where i stand 🙂 as i am probably in over my head with 9 ingredients already. But it will be a fun exercise to try group ingredients and learn how you built up the various notes. Such discoveries will be inspiring.
My idea with the 9 ingredients is to make the pepper the star of the open and only use a small amount of bergamot to launch the pepper from.
Bayberry with a heavier spice note and its bitter green as a bridge to the heart.
There frankincense i like to be the elegant star. A small amount of cipres to extent the freshness and green and the dry wood of the cedar to ground the frankincense and bridge.
In the base the oakmoss for a light impression of a forest with only a small amount of oud as a distant darkness. The benzoin adding warmth and keeping the leather and tobacco notes from becoming to heavy. The oakmoss outlives the oud with easy so that darkness kind of fades away.
The scent i borrowed the notes from is said to be Tibet inspired and about motion. If there is anything Tibet about my interpretation, then for me it's in the base: seeing the darkness, let it be, let it fade. But that only occured to me after trying the oud oakmoss combination.
When creating with few impactful ingredients there are two challenging issues -
first is the aromatic sharpness, the domineering harshness and the overwhelming power of some materials that can obliterate the less powerful materials - when present in high percentage; Spices are like that (Bay and Pepper), so while conceptually a spice may be central, quantitatively it need to be really minor - 1-2% from the Top's share is quite plenty.
Another issue is Safety by using high doses of 'difficult' ingredients - like uncut Oakmoss - which I like personally too, but which also requires light hand; also, Oakmoss is relatively dominant material.
Thus, such simple compositions are in fact very difficult to balance and unite without any additional ingredients - those that bridge and moderate and help the Unison and Cohesion.
Bergamot (Bergaptene-free) in a relatively high dose can help unify all the challenging top notes - as among its many other beneficial traits, Bergamot is a 'hugging chameleon' - becoming a radiant encapsulation, a supporting background for sharper materials.
In the Base, If I would be limited to a single ingredient to unify, smooth and fixate it all - in the 'Tibetan Mood' composition - and create a fused 'Mandala' of the scent, I'd go with Sandalwood.
Benzoin is fine but its sweetness and cinnamic edge can be sometimes overbearing and cloying (for my personal dislike of it), although it is more a matter of taste than of functionality, and it can be present in high doses (up to 20-25% of the composition).
As for the bigger, general issue of the 'Orchestration' of complex and very complex compositions, it is really like with Symphonic music -
- know the strength, the intensitiy and longevity of each of your 'tones' - the materials,
- define your main melodic theme, your aromatic ambience - 'the vision, as well as important supporting and developing nuances to it;
and then create the Major Line ('the Leitmotif') of 2 to 6 ingredients as the 'Temporal Backbone', from the top of Top to the bottom of the Base; add the conceptual nuances that accentuate the theme in the right places - from different facets of it - in the quantities at least a magnitude less than the main elements; also, balance anything 'screeching', and seal the aromatic gaps - with master 'gap-sealers' (Bergamot, Orange, Rose, Rosewood, mellow Sandalwoods, Cistus and Labdanum function as such - at various layers of the fragrance);
- then think of 'Fioritura' - some decorative and whimsical little elements (mostly in traces up to max 1-2%), although it is a matter of style - as with rich and grand ingredients used at the center (a high-class Oud is a good example), there is less need in multiple secondary decorative distractions:
-last, think of the functional necessities, like continuity, radiance, fragrant volume ('the Body'), tenacity - and add what may improve those according to the detected need(s) - while staying within the central defined theme - by choosing the goal-matching mateirals.
In general, every element must serve the core character and the conceptual purpose, in accordance with its traits and properties you identify and appreciate - in your personal view
