Well, is perfumery an art? I posted to my blog on this question as it relates to the notion of aesthetics. You can find it at this link.
Music is a wonderful thing, one which I love greatly, though being a singer, it is vocal music I know and love best. In one of my blog posts, I compare perfumery to the visual, plastic, and musical arts. Here's one paragraph dealing a bit with music:
The aesthetic issue about scent for me is how the appreciation of it draws me out of and even beyond myself. Scent is in some mysterious way the most sublime of the fine arts. Perhaps this is even because it marries the deepest-buried human-animal perception [the sense of smell] and our impulse to the most rarefied and ungraspable notion of beauty. The utilitarian and social, even intellectual aspects of interest in scent pale by comparison to the pure aesthetic enjoyment of it. The development of a refined taste in scent is an exercise in the exploration of aesthetic sensibility on a plane beyond the visual and plastic arts. The Golden Mean and the Fibonacci series seem to underlie a natural aesthetic of the eye; but what accounts for the structure of an aesthetical basis for the perception of scent? Is there any mathematical formula that can unlock our understanding of it? Even music can be understood in terms of consonances and cadences based on mathematical relations of tonal proportions -- ratios of vibrations in cycles per second; durations in time that form the basis of rhythm and tempo. These are far better known than the principles that underlie the appreciation of scent. How do we wrap our minds around some of these issues? [Emphasis added.]
