We investigated the effect of music on emotions that were induced by two essential oils (peppermint and lavender). Participants (n=16) sniffed the stimuli of peppermint and lavender, and evaluated the emotional values while two pieces of music, one delightful and one gloomy, were presented. We found that the emotional values for the fragrances of these olfactory stimuli were influenced by the emotions induced by the music: delightful music enhanced the delightful mood induced by one of the essential oils (lavender), and gloomy music reduced the delightful mood induced by both oils.
