The note of "Autumn Leaves" is a complex tapestry, immediately evocative of crisp, cool air and the scent of the forest floor after a frost. Its initial impression is often a dry, slightly brittle texture, like crushed foliage underfoot, leading into a rich, earthy warmth. It carries a distinctive aroma of decaying vegetation, not in a putrid sense, but rather a beautiful, almost sweet decomposition, mingled with hints of smoke from distant bonfires. There's a woody undertone, sometimes resinous, and a subtle spiciness, reminiscent of fallen oak or maple. The projection is moderate, initially quite present, then settling into a grounding, skin-close hum. It evolves from a sharper, almost metallic greenness in its top facets (representing newly fallen leaves) to a deeper, more enveloping, and slightly damp earthiness as a heart and base note, with excellent longevity that anchors a composition.
