The note unfolds with an initial powerful, almost formidable presence, a deep, resonant growl that is simultaneously leathery and smoky, with an earthy bitterness that suggests ancient forests and damp, rich soil. Its 'black' character manifests as an obsidian darkness, a profound, unyielding warmth that slowly reveals nuances of dried fruits, dark chocolate, and sometimes a whisper of green, almost medicinal mentholation or camphoric coolness beneath its formidable heat. There's a distinct animalic facet, not overtly fecal but rather a clean, musky hide quality, akin to a fine, aged leather. It possesses an incredible intensity and projection, often dominating a composition for hours, evolving from its initial ruggedness into a smoother, balsamic, almost honeyed resinousness over many, many hours. It is unequivocally a base note, a foundational anchor that can linger for days on fabric, a testament to its exceptional longevity.
