Courtney Humphries’s “The great sensory mix-up’’ (Ideas, Dec. 11) was quite interesting to me. As an artist, I am well aware of the synergy that results within the senses, and believe most artists are too. Synesthesia is the intake of one aesthetic sense with the result of other senses arising. For example, one can look at a painting and have it bring back music to the ears. In the same way, one can imbue an art gallery with music and good wine and have the exhibition come off more successfully, as the entire experience creates a treat for the senses.
