The top or initial notes, woven from light and volatile components, give the composition its initial sound and create a mood. These notes last for a few minutes and prepare for the main fragrance.

The bright sound of the top notes smoothly transitions into the main accord – the heart notes. This is where the main melody plays, defining the fragrance's family, character, and recognizability. They can last up to 2 hours.

The heart notes transition into the warmth of the final, trailing, or base notes. These notes give the composition a sensual sound, ensure the longevity of the composition, and determine its richness. They can last up to 8 hours.

The duration of the notes depends on the fragrance composition, skin characteristics, application method, and is provided as an estimate.
