Various notes can also be blended to form an accord, which is a less specific form of classification for ingredients in a scent. “In the same way you hold down several notes in music to create a chord that has a unique sound, in perfume, an accord[, the french word for “chord”,] is a scent made up of several perfume notes, or ingredients, that blend together to form a distinct fragrance. For example, the classic accord in the chypre perfume category is bergamot, labdanum, and oakmoss.” (Herman, 2016) In a fragrance, the concentration of the different note groups and accords varies. Head notes usually consist of 20% to 25% of the fragrance, while 25% to 30% is heart notes and 50% of a fragrance is made up of the end notes.
