Having a Drink with Tchaikovsky: The Crossmodal Influence of Background Music on the Taste of Beverages

Previous research has shown that auditory cues can influence the flavor of food and drink. For instance, wine tastes better when preferred music is played. We have investigated whether a music background can modify judgments of the specific flavor pattern of a beverage, as opposed to mere preference. This was indeed the case. We explored the nature of this crosstalk between auditory and gustatory perception, and hypothesized that the 'flavor' of the background music carries over to the perceived flavor (i.e., descriptive and evaluative aspects) of beverages. First, we collected ratings of the subjective flavor of different music pieces. Then we used a between-subjects design to cross the music backgrounds with taste evaluations of several beverages. Participants tasted four different samples of beverages under two contrasting audio conditions and rated their taste experiences. The emotional flavor of the music had the hypothesized effects on the flavor of the beverages. We also hypothesized that such an effect would be stronger for music novices than for music experts, and weaker for aqueous solutions than for wines. However, neither music expertise nor liquid type produced additional effects. We discuss implications of this audio-gustatory interaction.
