Up to the present day there is still a lack of research on the interaction between music/sound and flavour/taste. The main question is whether the psychological reality has a physiological origin, is formed by culture, or whether it is simply a figment of the imagination without physiological basis. The aim of the present study is to validate methods for research on the relation between music and flavour. Two experiments were conducted, in which flavours had to be imagined (virtual, online) or really tasted (real, laboratory). Short sound samples, varied in basic acoustic parameters, were used as auditory stimuli. Five modes of measurement were tested:
1. Verbal free association,
2. Ratings with selected adjectives, which were considered to describe intermodal properties,
3. Matching sounds of different acoustic properties with flavours,
4. Matching visual stimuli with flavour-related sounds,
5. Matching of flavour-related sound with tactile stimuli (virtual and real situation).

The experiments led to the conclusion that flavours can be discriminated by either method. Remarkable were differences between the virtual and real presentation of the flavours. The results from the matching experiments enabled the design of audio logos (3 seconds duration) and sound moods (15 seconds duration), significantly related to the intended flavour.
