You will often see top, middle, and base notes being used to describe a fragrance.
The top notes of a fragrance, also known as the head or opening notes, are what you smell immediately after spraying your perfume or aftershave; they evaporate quickly but will form the first impression of the fragrance.
The middle or heart, notes appear once the top notes have disappeared. These notes are the main body of the fragrance, lasting longer than the top notes and are usually well-rounded.
